What the ratings mean for fit
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.
Panel integration and footprint
At 105 mm wide, 181 mm tall, and 86 mm deep, this MCCB fits standard SENTRON mounting patterns and leaves room for auxiliary switches in the DIN-rail enclosure. 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. Power loss is 6.5 W maximum — negligible for thermal budgeting but worth noting if the panel is densely packed.
