What this MCCB is and where it fits
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. It carries a shunt trip release (STL) and two auxiliary switches (HQ), making it suitable for remote tripping and status monitoring in automated systems — including AS/RS crane power feeds where a fault must be signaled back to the PLC without a separate control relay.
Breaking capacity — what the numbers mean for your fault duty
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. Those are the maximum interrupting ratings at each voltage level — the breaker can safely clear a fault up to that current without welding contacts or rupturing the case. 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. Storage range is -40 °C to 80 °C.
Physical footprint and panel fit
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. Depth of 86 mm leaves clearance for rear-connected lugs in a standard 200 mm deep enclosure.
