Product details

Line protection MCCB with high interrupting capacity

The Siemens SENTRON 3VA1040-4ED32-0KH0 is a 3-pole molded case circuit breaker rated for line protection, carrying a continuous current of 40 A up to 50 °C and derating to 36 A at 70 °C. Its interrupting capacity reaches 121 kA at 240 V and 75.6 kA at 415 V — figures that place it in the high-fault tier for industrial distribution panels where available fault current is substantial. That alarm contact closes only on a fault trip, giving the PLC or annunciator a dedicated signal that distinguishes overload from manual switching.

Panel fit and mounting constraints

At 70 mm deep, 76.2 mm wide, and 130 mm tall, the 3VA1040-4ED32-0KH0 fits the standard SENTRON 3VA footprint.
