The Siemens SENTRON 3VA2110-5MN32-0CL0 is a 3-pole molded case circuit breaker (MCCB) rated for motor protection duty. It carries 100 A continuously across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting. The interrupting rating hits 187 kA at 240 V AC, stepping down to 121 kA at 415/440 V and 75.6 kA at 500 V, with a sharp drop to 3.7 kA at 690 V — so the 690 V figure governs if that is your line voltage.
Built-in protection and release package
This MCCB ships with an undervoltage release (UVR) and phase failure detection as standard — both are integrated, not add-on modules. The auxiliary switch complement is two auxiliary switches plus one trip alarm switch plus one electrical alarm switch, HQ design. That means the breaker reports its status (open/closed, tripped, alarm) without external interposing relays, which saves DIN rail space in the control panel.
Panel fit and dimensions
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or backplate layouts. The 86 mm depth is the dimension to check against enclosure depth if a door-mounted operator or a deep auxiliary module sits behind the breaker.
