63 A MCCB for line protection with high interrupting capacity
The Siemens SENTRON 3VA2163-5JP32-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, designed for line protection in distribution panels and industrial switchgear. Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — meaning it can safely clear faults up to those levels without upstream cascading, which is critical for selectivity coordination in a multi-level distribution system. The breaker carries a communication function and includes a shunt trip release (STL) as the auxiliary release, plus a complement of 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch. There is no undervoltage release and no ground-fault monitoring version on this variant — specify those separately if your circuit requires them.
Integration and mounting
The 3VA2163-5JP32-0KL0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard MCCB footprint that fits Siemens SENTRON mounting bases and most DIN-rail adapter plates for panel integration. Operating temperature range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. Maximum power loss is 4 W.
Selectivity and coordination note
With a minimum trip setting of 95 A and maximum of 756 A, this breaker provides a wide adjustment band for coordinating with downstream branch circuit breakers. The trip indicator and voltage trigger give clear status feedback for troubleshooting. Designed for line protection, it is not a motor-protective device — use it for feeder or main breaker duty in a distribution panel.
