It carries a full-load current rating of 100 A at 40 °C, and that rating holds flat through 50 °C before a gentle derating curve begins: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. The 3-pole frame occupies a 76.2 mm wide footprint on the DIN rail, with a depth of 70 mm and height of 130 mm. Breaking capacity is voltage-dependent, as you'd expect on a high-interrupting MCCB: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 187 kA figure at 240 V puts it in the high-fault category for North American panelboards fed from a large transformer. The rated insulation voltage is 800 V, giving headroom for 690 V systems. This variant ships with a shunt trip (STL) auxiliary release and two HQ auxiliary switches built in — no undervoltage release, no ground-fault monitoring, no communication module. The shunt trip lets you remotely trip the breaker via a control signal, which is typical for emergency-stop circuits or supervisory PLC override. Maximum power loss is 25 W, so factor that into enclosure thermal calculations. ## Panel fit and integration notes The 76.2 mm width (3 inches) matches the standard 3-pole MCCB footprint on a DIN rail. Depth of 70 mm (2.76 in) and height of 130 mm (5.12 in) are typical for this frame class.","metaTitle":"Siemens 3VA1110-5MH32-0JC0 SENTRON MCCB, 100 A, 3-Pole, 70 m","metaDescription":"Siemens 3VA1110-5MH32-0JC0 SENTRON molded case circuit breaker, 100 A rated at 40 °C, 3-pole, 187 kA at 240 V.
