It's built for motor protection (the design designation says so), with phase failure detection and a trip indicator that tells you which phase took it out. That matters when you're trying to decide whether it's a load fault or a supply problem. Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V, and holds 75.6 kA at 500 V before dropping to 3.7 kA at 690 V. That's a lot of headroom for most industrial panels — the 415 V figure covers common European and Asian distribution voltages with room to spare for high-fault utility feeds. The UVR means the breaker drops if control voltage disappears — useful for safety circuits or remote emergency-stop chains where you want the load isolated when the control power dies. The auxiliary switches let the PLC or SCADA know the breaker's position without running separate limit switches. The basic switch inside is order code 3VA21105MN320AA0, so if you're panel-building and need the bare switch module separately, that's the number. Max power loss is 12.5 W — modest for a 100 A frame, keeps the enclosure heat rise manageable. The 86 mm depth (3.39 in) leaves room for rear-connected busbars or cable ladders behind the breaker.","metaTitle":"Siemens 3VA2110-5MN32-0BH0 SENTRON MCCB, 100 A, 3-Pole","metaDescription":"Siemens 3VA2110-5MN32-0BH0 SENTRON molded case circuit breaker, 100 A rated, 3-pole, 121 kA at 415 V.
