DEHNrail M 2P ...:
Two-pole surge arrester consisting of a base element and plug-in protection module 
DEHNrail M 2P ... FM: With remote signalling contact for monitoring device (floating changeover contact)
For protecting the power supply of industrial electronic devices against
surges in switchgear installations.
The new modular devices of the DEHNrail M product family impress the
users with their high performance parameters and new clear Red/Line
design. The device combines safety and easy handling in only one module
to a convincing synergy. The low voltage protection level as well as the
comprehensive protection against common-mode and differential-mode
interferences are designed for protection of industrial terminal electronic
devices in an optimal way. The design of the devices with input and out-
put terminals for series connection and the protective circuit designed for
high load currents underline this concept.
The very compact design of the DEHNrail M devices includes the distinc-
tive Y protection circuit and the combined SPD control and disconnector.
The coding integrated into the base part and protection module prevents
wrong supplying by the installer or user.
The new module locking system of the DEHNrail M product family is
unique for surge protective devices. It connects the surge protection mod-
ule tightly with the base part of the SPD. Neither vibrations during trans-
port nor the electromagnetic forces of discharges can loosen this connec-
tion.
If the protective circuit is overloaded despite of the powerful characteris-
tics of the devices, the module releasing button allows for quick exchang-
ing of the protection module.
Apart from the standard visual indication by the green and red marking,
type DEHNrail M ... FM has a 3-pole terminal for remote signalling. As the
remote signalling contact is a floating changeover contact, the remote
signal can be used as break or make contact, according to circuit concept.
