The Siemens SENTRON 3VA2110-5HL32-0BC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity reaches 187 kA at 240 V and 121 kA at both 415 V and 440 V, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V. That SCCR headroom at typical distribution voltages means it can sit upstream of a fault without cascading to the main breaker, which is the deciding factor for selectivity studies in a switchboard. Designed for line protection with an undervoltage release and two HQ auxiliary switches.
Footprint is 105 mm wide by 181 mm tall by 86 mm deep (4.13 x 7.13 x 3.39 in). The 3-pole form factor fits standard SENTRON panel cutouts.
Peer Comparison
The closest functional peer in the same SENTRON family is the 3VA2116-5HL32-0AK0. Both are 3-pole MCCBs with the same 100 A continuous rating and identical SCCR values at every voltage level. The difference is in the auxiliary switch configuration: the -0BC0 carries 2 HQ switches, while the -0AK0 carries a different auxiliary switch variant. For a panel originally specified around the -0AK0, the -0BC0 will drop into the same cutout and bus connection without rewiring — the mounting footprint and terminal layout are shared across the 3VA2 frame. The only check is whether the auxiliary contact count and function match the control circuit design.
