SENTRON 3VA1196-5GF42-0AC0 — 16 A 4-Pole MCCB with TM240 Release
The Siemens SENTRON 3VA1196-5GF42-0AC0 is a 4-pole molded case circuit breaker rated 16 A continuous, built around a TM240 thermal-magnetic overcurrent release. It is designed for line protection — the primary feeder or distribution circuit — not motor or generator protection. The interrupting ratings climb steeply with lower voltages: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and a 17 kA floor at 500 V and 690 V. That SCCR curve makes this breaker a strong candidate for high-fault panels where a standard MCB would not hold coordination. Rated insulation voltage is 800 V, and the breaker dissipates 10.6 W maximum at full load. The thermal derating is minimal up to 55 °C (still 16 A), then drops to 15 A at 60 °C through 70 °C. Ambient operating range spans -25 °C to 70 °C, storage from -40 °C to 80 °C.
Panel Fit and Mounting
The 3VA1196-5GF42-0AC0 measures 70 mm deep, 101.6 mm wide, and 130 mm tall. It carries two auxiliary switches (HQ type) as built-in accessories. No undervoltage release, no ground-fault monitoring, no communication module — this is a straight line-protection breaker with a thermal-magnetic trip unit. The basic switch variant is 3VA11965GF420AA0.
