At 240 V it breaks 75.6 kA; at 415 V it's 52.5 kA; at 440 V it drops to 32 kA; and at 690 V it's 10.5 kA. For a 400 V panel with a prospective short-circuit current of, say, 40 kA, the 52.5 kA rating at 415 V gives comfortable headroom. At 690 V the 10.5 kA limit means this breaker is only suitable for systems with low fault levels — check your coordination study before specifying it on a 690 V bus. ## Thermal derating — the real-world current you can run Above that, the derating curve is gradual: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. If your panel ambient runs 55 °C inside a non-climate-controlled enclosure, you lose about 4% of the continuous rating — plan your load accordingly. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that mounts on a DIN rail or directly to a backplate via the screw terminals. A shunt trip (STL) is built in for remote tripping; the auxiliary release order code for the integrated trip unit is 3VA9688-0BL33. No auxiliary contact block is fitted as standard.","metaTitle":"Siemens 3VA1116-3EF36-0KA0 SENTRON MCCB, 160 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1116-3EF36-0KA0 molded case circuit breaker, 160 A rated continuous current, 3-pole, line protection.
