D-U300 relay – Plug-in, 4 pole, AC coil

Categories: , , ,

Description

Plug-in railway relay with 4 change-over contacts suitable for AC coil voltages with a frequency of 50/60 Hz.
Proven reliable operation in switching high DC voltage / inductive loads and low currents. Standard equipped with magnetic arc blow-out for high breaking capacity and long contact life. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions.
The construction of the relay and choice of materials makes the D-U300 relay suitable to withstand corrosive atmospheres, low and high temperatures, shock & vibrating and dry to very humid environments.
Compact design, choice of many options and a wide range of sockets makes the D-U300 relay an easy and flexible solution to use.
