The Siemens SENTRON 3VA1196-3EF42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying a TM240 thermal-magnetic release and a continuous current of 16 A up to 55 °C ambient — no derating needed until 60 °C, where it steps to 15 A. The interrupting capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and still holds 11.9 kA at 690 V, so it handles high-fault service-entrance and distribution panels without cascading upstream breakers.
Sizing and selectivity
That keeps the part simple and repeatable for BOM consistency: every unit in the panel trips at the same curve.
Dimensions are 101.6 mm wide, 130 mm high, 70 mm deep — a standard 4-pole MCCB footprint that drops into most DIN-rail or screw-mounted SENTRON bases without re-drilling the backplate.
