That thermal profile matters when you're packing breakers into a warm enclosure and need to know your headroom without guessing. Breaking capacity is where this breaker earns its keep: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 500 V and 690 V. That's high-fault rated for a 40 A frame — useful downstream of a large transformer or on a high-capacity bus where a standard MCCB would need upstream fuses for coordination. ## Built-in accessories and panel fit The two aux switches give you status feedback (open/closed) for the PLC or annunciator without adding external interface relays. Dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — a 3-pole MCCB that fits standard distribution panel mounting.","metaTitle":"Siemens 3VA1140-6EF36-0CC0 SENTRON MCCB, 40A, 3-Pole, 220 kA","metaDescription":"Siemens 3VA1140-6EF36-0CC0 SENTRON molded case circuit breaker, 40A rated at 40°C, 3-pole, 220 kA breaking capacity at 240V AC.
