SENTRON 3VA1116-5EE42-0AA0 — 160 A MCCB for Line Protection
The Siemens 3VA1116-5EE42-0AA0 is a 4-pole molded case circuit breaker from the SENTRON 3VA family, configured for line protection with a TM220 thermal-magnetic trip unit. It carries a continuous current of 160 A at 40 °C ambient, derating to 150 A at 70 °C. Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 440 V, with a floor of 17 kA at 500 V and 690 V. That gives you selectivity headroom for high-fault utility feeds or transformer secondaries where downstream gear needs a hard limit.
Mounting and Integration
The breaker measures 130 mm high, 101.6 mm wide, and 70 mm deep — a standard 4-pole MCCB footprint for panel-mount installation. Front-face protection is IP40, suitable for enclosed distribution boards where splash and tool ingress are controlled. Rated insulation voltage is 800 V, and the operating voltage ceiling is 690 V AC. Maximum power dissipation is 38 W at full load — factor that into enclosure thermal calculations if you are packing multiple breakers in a sealed cabinet.
