It's built for line protection in distribution panels and motor control centers where you need high interrupting capacity — 242 kA at 240 V and 187 kA at 415 V — so it handles fault currents at the main or sub-main level without cascading upstream. At 690 V the breaker still clears 3 kA, which is enough for most industrial line-to-line faults in a 690 V system. The ETU850 trip unit supports adjustable overload and short-time pickup, so you can coordinate with downstream breakers and avoid nuisance trips. The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panels. The front face is IP40, so it's suited for enclosed switchboards.","metaTitle":"Siemens SENTRON 3VA2040-6KP32-0AA0 MCCB, 40 A, 3-Pole, 242 k","metaDescription":"Siemens SENTRON 3VA2040-6KP32-0AA0 molded case circuit breaker, 40 A, 3-pole, 242 kA breaking capacity at 240 V.
