Four poles, line protection version, fitted with the ETU850 electronic trip unit. The interrupting ratings are substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V.
Communication function is onboard, so it can report status and trip events to a higher-level control system without an add-on module.
242 kA at 240 V, which covers virtually any industrial service entrance fault level in North America.
The ETU850 electronic trip unit, which provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves.
