The interrupting curve drops sharply above 440 V: 75.6 kA at 440 V, then 17 kA at 500 V and 690 V. If your fault current at 480 V exceeds 17 kA, this breaker won't clear it — you need a higher-rated frame. The 3-pole design with shunt trip (STL) and two auxiliary switches plus a trip alarm switch (HQ) means it can signal a remote PLC on fault and be remotely tripped for emergency stop circuits. Mounts on a DIN rail or direct panel — the 76.2 mm width (3 inches) and 130 mm height (5.12 inches) fit standard MCCB slots in most distribution boards. Depth is 70 mm (2.76 inches), leaving room for cable bending radius behind the breaker. The shunt trip and auxiliary switches are factory-fitted, so no field assembly of accessories.","metaTitle":"Siemens 3VA1140-5EF36-0HH0 SENTRON MCCB, 40 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1140-5EF36-0HH0 molded case circuit breaker, 40 A rated, 3-pole, 187 kA interrupting at 240 V.
