The Siemens SENTRON 3VA2063-5HN36-0CH0 is a 3-pole molded case circuit breaker rated for 63 A continuous current with no derating across the full operating temperature band of -25 °C to 70 °C — the breaker delivers its full 63 A at every point in that range, not just at 40 °C. Interrupting capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V, per the datasheet figures.
Panel footprint and mounting
Auxiliary release and switch complement
The trip alarm switch changes state only when the breaker trips on fault, providing a separate signal for remote fault indication. The basic switch assembly is order code 3VA20635HN360AA0.
Thermal and power dissipation
Maximum power loss is 7.9 W at rated current. The trip indicator is present, giving local mechanical indication of trip state without needing to open the door.
