What this MCCB delivers — 250 A continuous, 330 kA interrupting at 240 V
It carries a 3-pole line protection configuration with an ETU850 electronic overcurrent release, giving you adjustable trip curves and communication capability for selective coordination studies. Breaking capacity is 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, 187 kA at 500 V, and 6.3 kA at 690 V — numbers that place this breaker in the high-interrupting category for large service entrances or heavy industrial feeders.
Auxiliary contacts and trip options built in
A voltage trigger is present; undervoltage release is not. The breaker also has a mechanical trip indicator and latching endurance rated at 20,000 operations.
The 105 mm width matches the standard 3-pole MCCB slot in most switchgear lineups. The ETU850 release is field-configurable via the front face — no need to pull the breaker for trip-curve changes.
