DEHNrail M 2P ...: Two-pole surge arrester consisting of a base part and a plug-in protection module
DEHNrail M 2P ... FM: With remote signalling contact for monitoring device (floating changeover contact)


Details

 
The modular devices of the DEHNrail M product family stand out due to their high performance parameters and straightforward Red/Line design. The devices combine safety and ease of use in a single module. The low voltage protection level and the comprehensive protection against common-mode and differential-mode interference make them ideal for protecting terminal equipment in industrial electronics environments. The input and output terminals for series connection and the protective circuit designed for high load currents underline this concept. 

The very compact design of the DEHNrail M surge arresters includes the fault-proof Y protective circuit and a combined SPD monitoring and disconnection device. 

The base part and protection module are coded to ensure against installing an incorrect module.

The unique module locking system of the DEHNrail M product family fixes the protection module to the base part. Neither vibration during transport nor the electrodynamic forces of discharge can loosen the connection. 

In the event of the protective circuit being overloaded, the protection modules can be easily replaced without tools by simply pressing the module release button.

In addition to the standard visual indication with green and red indicator flags, DEHNrail M ... FM devices feature a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as a break or make contact according to the particular circuit concept.

Details

 

 

The modular four-pole DEHNrail M 4P ... (FM) surge arresters are specifically developed for protecting three-phase industrial electronics terminal equipment. Adapted to this kind of environment, the arresters with the Red/Line design are suitable for 35 mm DIN rails. The low voltage protection level and the comprehensive protection against common-mode and differential-mode interference are characteristic of DEHNrail M 4P ... (FM). To provide optimal low voltage protection levels for the terminal equipment to be protected, the device features input and output terminals for series connection. DEHNrail M 4P ... (FM) devices ideally adapt to the cable run upstream of the terminal equipment. Therefore, no additional terminal blocks for outgoing cables are required. The compact design incorporates the tried and tested disconnector. It disconnects an overloaded arrester circuit without interrupting the supply circuit. 

The base part and protection module are coded to ensure against installing the incorrect module.

The unique module locking system of the DEHNrail M family fixes the protection modules to the base part. Neither vibrations during transport nor the electrodynamic forces of discharge can loosen the connection.

In the event of the protective circuit, which is rated for high load currents up to 25 A, being overloaded, the protection modules can be easily replaced without tools by simply pressing the module release button. 

Apart from the standard visual indication with green and red indicator flags, DEHNrail M 4P ... FM devices feature a three-pole remote signalling terminal. With its floating changeover contact, the remote signal can be used as a break or make contact according to the particular circuit concept.

SPS Protector: Two-pole surge arrester with interference suppressor filter


Details


The SPS Protector combines surge protection and interference suppressor filter in a compact device. This makes it ideal for protecting sensitive terminal equipment of industrial automation systems (e.g. programmable logic controls (PLCs)). The coordinated surge protection and filter functions complement one another and prevent core saturation of the filter in the event of high-level transients. The separate input and output terminals provide optimal protection for the device to be protected. The metal enclosure of the SPS Protector ensures that high-frequency interferences are discharged without interfering with other devices in the immediate vicinity. The compact design of the SPS Protector already houses the proven disconnector. In case of overload, it disconnects the arrester without interrupting the power supply circuit. Apart from the green indicator light, SPS Protectors also feature a remote signalling contact.

DEHNsafe 230 LA: Surge protective device for use in cable ducts

Details


 

 

DEHNsafe surge arresters particularly stand out due to their flexible application options. Thanks to their small mounting depth of only 31 mm, the two-pole surge protective devices for 230 V terminal equipment can be installed both in cable ducts and in flat flush-type boxes. DEHNsafe incorporates a monitoring device and a thermal disconnector. In addition to a visual operating state indicator, the device features a programmable acoustic fault indicator which can be programmed for three different operating states:
– Acoustic fault indication, 
– Test function, 
– Muting of the acoustic signal.

DEHNsafe surge arresters are covered by a triple TAE cover from any switch range manufacturer, thus ideally adapting to any socket outlet design.
The double terminals for L, N and PE allow for series connection to ensure that the surge protective device is situated in parallel to the circuit to be protected. For this reason, DEHNsafe does not necessarily interrupt the circuit to be protected in case of overload. They feature a green and red LED for visual inspection.

As the name suggests, the DEHNflex family offers almost unlimited application options. Being two-pole surge arresters, the compact modules are ideally suited for protecting electronic loads in final circuits. The design was adapted to the most common places of installation, that is cable ducts and flush-type boxes. DEHNflex devices show that small and compact dimensions do not necessarily mean that surge arresters are inefficient. The fault-proof Y protective circuit always ensures safety even if the phase and neutral conductors cannot be identified. Apart from the powerful Y circuit, the compact enclosure also houses a disconnector and an acoustic fault indicator. Be it in cable ducts, flush-mounted systems, branching boxes or device casings – DEHNflex is always installed in the right place close to terminal equipment.

DEHNpro 230 F: Protection of terminal equipment with mains filter
 
Details

 
The adapters with integrated surge protection of the DEHNpro family protect electronic loads connected to final circuits from overvoltage. An interference suppressor filter with a balancing and unbalancing effect was integrated in the powerful surge protective circuit of DEHNpro 230 F Protectors. This combination of surge protection and filter prevents a core saturation of the filter in case of high-level transients. The nominal current carrying capability of 16 A (DEHNpro 230) and 10 A (230 F Protector) allows flexible use of these devices in final circuits. The fault-proof Y circuit ensures protection even if the phase and neutral conductors in standard earthed socket outlets cannot be identified. The integrated disconnector ensures reliability of devices and installations. The standard green and red LEDs indicate the operating state of the surge protective devices.
The modern design of the DEHNpro devices and the use of high-quality materials ensure safety in a sophisticated appearance. The DEHNpro devices thus ideally adapt to the installation environment. They create the right technical environment already at the socket outlet for connecting the latest communication and multimedia systems. The curved enclosure surfaces and the smooth surface structure ensure that the DEHNpro devices will not lose their original properties even after several years of application.
