The Siemens 3VA2163-5HL32-0JC0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current, with a 3-pole configuration designed for line protection in distribution panels and industrial switchgear.
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. For a 480 V panel with a 100 kA available fault current, this unit provides headroom; at 690 V the 3.7 kA limit means it's only suitable for low-fault-capacity circuits at that voltage.
Thermal performance across ambient temperature
The 63 A rating holds flat from 40 °C through 70 °C ambient — no derating needed up to the maximum operating temperature. That simplifies panel design in warm environments like motor control centers or enclosed switchgear.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep. The 105 mm width is standard for a 3-pole MCCB in this frame size, so it drops into existing SENTRON 3VA2 panel layouts without busbar rework.
