Breaking capacity across voltage levels
This MCCB's interrupting capacity drops as system voltage rises — 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That steep fall at 690 V tells you this is a 480 V-class breaker, not a 600 V-class one. For a 480 V delta or 277/480 V wye service, the 187 kA rating gives plenty of headroom for most industrial SCCR requirements.
Integrated shunt trip for remote tripping
The factory-fitted shunt trip (STL) release lets you trigger a trip from a remote push button, a safety relay, or a PLC output — useful for emergency-stop circuits or automated load shedding. No undervoltage release on this variant, so it won't drop out on a brownout; the shunt trip is the only auxiliary release.
Panel builders will find the 10 W maximum power loss manageable within typical enclosure thermal budgets. The line-protection design means it coordinates downstream with smaller branch breakers.
