MCCB for high-fault panel feeds
At 415 V and 440 V the breaking capacity holds at 121 kA, dropping to 79 kA at 500 V and 5.1 kA at 690 V — so the voltage class of the distribution system governs which fault level this breaker can clear.
Maximum power loss is 48 W at rated current; factor that into enclosure ventilation if the panel is sealed or densely packed.
Trip unit and release configuration
The integrated shunt trip (STL) allows remote tripping via a control signal — useful for emergency-stop circuits or supervisory system override. No undervoltage release, no auxiliary contacts, no ground-fault monitoring, and no communication module are fitted on this variant. Mechanical endurance is 20,000 operations.
