MCCB for line protection, 16 A, 75.6 kA breaking capacity
The Siemens SENTRON 3VA1096-3ED32-0HA0 is a 3-pole molded case circuit breaker (MCCB) designed for line protection. It carries a continuous current rating of 16 A at 40 °C, derating to 15 A at 60 °C and above — so if your panel ambient runs hot, plan for the 15 A ceiling. The interrupting capacity is 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V; at 500 V and 690 V it holds 7.5 kA. That means this breaker handles high fault currents on the secondary side of a 240 V distribution transformer, but on a 690 V drive bus you need a higher-rated frame. The overcurrent release is a TM210 thermal-magnetic unit, and the auxiliary release is a shunt trip (STL) for remote tripping. Rated insulation voltage is 800 V. The breaker ships with the basic switch part 3VA10963ED320AA0 included.
Panel fit and dimensions
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width is a standard 3-module footprint — it clips onto a DIN rail or mounts directly in a panel. Maximum power loss is 10.6 W.
Comparison to 5SQ2370-2YA05
The closest functional peer in the evidence is the 5SQ2370-2YA05. Both are 3-pole MCCBs in the same SENTRON family, but the 5SQ2370-2YA05 is a different frame variant. The 3VA1096-3ED32-0HA0 includes a shunt trip (STL) as standard; the 5SQ2370-2YA05 may not. The 76.2 mm width and DIN-rail clip are identical, so it should drop in without rewiring, but verify the shunt trip wiring and any auxiliary contact positions.
