The 3VA2163-6HN36-0DL0 is a SENTRON molded case circuit breaker rated for 63 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to 70 °C, which simplifies panel design for hot environments like enclosed MCCs or outdoor cabinets. Its 242 kA breaking capacity at 240 V and 187 kA at 415 V cover high-fault scenarios near large transformers or busways; at 690 V the rating drops to 3.7 kA, so verify the available fault current on 690 V systems before specifying. The 3-pole design with undervoltage release (UVR) means it trips on loss of control voltage, a standard safety feature for motor branch circuits and emergency-stop chains.
The built-in trip indicator and the auxiliary switch configuration (2 aux + 1 trip alarm + 1 electrical alarm) reduce external wiring for status feedback to the PLC or SCADA.
