That continuous rating holds flat through 50 °C, then derates in 5 °C steps to 150 A at 70 °C — so in a warm enclosure you lose 10 A off the top, provided the ambient stays under 70 °C. The interrupting capacity steps down with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That matters when the breaker lands in a 600 V class motor control center — the insulation rating is not the limiting factor. ## DIN-rail footprint and auxiliary switch complement The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a 3-pole MCCB that fits a standard DIN-rail mounting footprint without overhanging the enclosure depth. The 76.2 mm width is three modular units at 25.4 mm per pole, so it occupies three adjacent 25 mm slots on the rail. Panel builders should account for the 70 mm depth when routing busbars or cables behind the breaker; the 130 mm height leaves room for a single row of auxiliary contacts above the main body. That trip alarm is useful for remote fault annunciation in a PLC input.","metaTitle":"SENTRON 3VA1116-5EF36-0AH0 MCCB, 160 A, 3-Pole, 187 kA at 24","metaDescription":"SENTRON 3VA1116-5EF36-0AH0 molded case circuit breaker, 160 A continuous, 3-pole, TM240 release.
