It's a 3-pole unit designed specifically for motor protection, with built-in phase failure detection so it catches a lost phase before the motor cooks. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and still carries 75.6 kA at 500 V. The 5 kA limited-to-1-second rating tells you the short-time withstand for coordination studies. It has a voltage trigger indicator and no communication module — it's a standalone protective device, not a smart breaker. The trip indicator is absent, so you'll need to verify trip status visually at the handle. The 3VA2440-5MN32-0KA0 measures 138 mm wide by 248 mm tall by 110 mm deep. That's a standard footprint for a 400 A SENTRON frame — it'll drop into existing 3VA panel cutouts without re-drilling. The 110 mm depth (4.33 in) means it fits shallow enclosures where a full-size air breaker won't.","metaTitle":"Siemens 3VA2440-5MN32-0KA0 SENTRON MCCB, 400 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2440-5MN32-0KA0 SENTRON molded case circuit breaker, 400 A continuous at 40-70 °C, 187 kA at 240 V, 3-pole motor protection with shunt trip.
