Can be tripped remotely with shunt/under voltage release.
Switches feature a fixed short‑circuit release (self‑protection) and comply to UL 489/CSA 22.2 No 5.1 regulations. Furthermore the switches are tested to IEC/EN 60947‑2 as circuit‑breakers without over current protection (CBI‑X) with main switch characteristics to IEC/EN 60204 and isolating characteristics to IEC 60947.
