Popis
Overvoltage and undervoltage monitoring railway relay with two change-over contacts. Suitable for AC 50 Hz voltages. Auxiliary power supply necessary, either DC or AC (0…60 Hz). When the relay is activated there is a delay on pull-in. The delay time is adjustable with a lockable knob. The overvoltage and undervoltage are also adjustable with a lockable knob.
The NSE-relay has a fail-safe circuit: also an auxiliary supply failure is detected.
The construction of the relay and choice of materials makes the NSE-relay suitable to withstand corrosive atmospheres, low and high temperatures, shock & vibrating and dry to very humid environments.
No external socket necessary, the relay can be mounted directly on a 35 mm rail without extra fasteners, or on any surface via 2 screws.
