The Siemens SENTRON 3VA1116-5EF42-0JH0 is a 4-pole molded case circuit breaker (MCCB) rated 160 A at 40 °C, designed for line protection in distribution panels. Its 187 kA interrupting capacity at 240 V gives substantial fault-clearing headroom for high-fault installations, while the 121 kA at 415 V and 75.6 kA at 440 V cover common industrial voltage levels. The breaker includes a shunt trip (STL) auxiliary release and two auxiliary switches plus one trip alarm switch HQ, allowing remote tripping and status feedback without an additional module.
Thermal derating and mounting
Current rating holds at 160 A from 40 °C through 50 °C, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. The 70 mm depth and 101.6 mm width fit standard panel cutouts for 4-pole MCCBs; the 130 mm height is compact for a 160 A frame. Mounting is via screw-clamp or optional DIN-rail adapter (not included), typical for SENTRON 3VA series integration into switchboards or sub-distribution boards.
