The interrupting capacity at 240 V AC is 75.6 kA, dropping to 52.5 kA at 415 V and 32 kA at 440 V, so this variant is sized for high-fault locations like main switchboards or transformer secondaries where short-circuit current runs high. ## Shunt trip and overcurrent release — what the TM240 + STL combination means The TM240 designation on the overcurrent release means the thermal element is calibrated for a 240 A frame, while the magnetic pickup is fixed and non-adjustable — typical for a thermal-magnetic MCCB where the thermal curve handles overloads and the magnetic element clears short-circuits. The shunt trip (STL) allows a remote signal (e.g., from an emergency stop button, a safety relay, or a PLC digital output) to open the breaker independently of the overcurrent condition. No undervoltage release is fitted, and no ground-fault monitoring module is included, so if either is required downstream, it must be added externally. ## Panel fit and ambient limits The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON panelboards and most DIN-rail or screw-mount enclosures.","metaTitle":"3VA1110-3EF32-0JA0 SENTRON MCCB, 100A, 75.6kA at 240V","metaDescription":"Siemens SENTRON 3VA1110-3EF32-0JA0 molded case circuit breaker, 3-pole, 100A rated at 40°C, 75.6kA interrupting at 240V AC.
