Product details

MCCB with 100 A continuous rating and 440 kA breaking capacity

The Siemens SENTRON 3VA2110-0KP42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 100 A continuous current and designed for line protection. It carries a 440 kA breaking capacity at 415 V AC and 187 kA at 690 V AC, which means it can safely interrupt fault currents up to those levels without upstream cascading — critical for high-fault installations like transformer secondaries or large motor control centers. The ETU850 electronic trip unit provides adjustable N-conductor protection (OFF, 20% to 160%) and includes communication and other measurement functions, making it suitable for integration into a power monitoring or energy management system.

Dimensions are 86 mm deep, 140 mm wide, and 181 mm high. The 4-pole design fits three-phase-plus-neutral panels.
