That 500 A holds flat through 50 °C — only starts to derate at 55 °C (495 A) and drops to 480 A by 70 °C, so it handles warm enclosures without a big margin hit. The interrupting ratings tell you where it clears faults: 330 kA at 240 V, 242 kA at 415 V and 440 V, and 52.5 kA at 690 V. It ships with an ETU350M electronic trip unit — that's the overcurrent release that gives you adjustable long-time, short-time, instantaneous, and ground-fault protection curves. The motor protection version means the trip unit is pre-configured for motor starting inrush and thermal memory, so it won't nuisance trip on a cold start. The UVR drops the breaker on loss of control voltage — standard for safety circuits where you need a guaranteed disconnect if the control supply fails. No ground-fault monitoring module is fitted, and there's no communication function onboard.
Panel integration and environment
Maximum power dissipation is 101.5 W — that's the heat you need to vent from the enclosure at full rated current. In a sealed panel with multiple breakers side by side, that heat adds up; plan for forced ventilation or a larger cabinet if you're running near 500 A continuously.
