It handles peak voltages up to 2 Uc, meaning it suppresses spikes up to 144 V peak for the rated 72 V coil. Rated for screw mounting directly onto TeSys D contactors or reversing starters.
This part is marked obsolete by the manufacturer. The suppressor technology (bidirectional peak limiting diode) is specific to TeSys D; a modern replacement may require a different mounting adapter or wiring scheme.
Operating temperature range is -13 to 131 °F (-25 to 55 °C); storage range extends to -40 to 176 °F (-40 to 80 °C). The module is a service part under category 18401, intended for field replacement on existing TeSys D installations.
