160 A MCCB with TM210 release — breaking capacity across the voltage range
The SENTRON 3VA1116-6ED42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying 160 A continuously at 40 °C through 50 °C without derating. At 55 °C it holds 158 A, at 60 °C it holds 155 A, at 65 °C it holds 153 A, and at 70 °C it holds 150 A — so the full 160 A rating is usable in most panel environments below 50 °C, and the derate curve is linear enough to plan around. The TM210 overcurrent release combines a thermal element for overloads and a magnetic element for short-circuits, set at the factory for the 160 A frame. Breaking capacity is 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — that 220 kA figure at 240 V covers most North American distribution fault levels, while the 154 kA at 415 V handles high-fault European grids. Rated insulation voltage is 800 V, so the breaker is suitable for 480/277 V and 400/230 V systems with margin. Power loss at rated load is 38 W maximum, which matters for thermal budgeting in a densely packed panel.
Panel fit and environment
The breaker measures 70 mm deep, 101.6 mm wide, and 130 mm high. The 4-pole width (101.6 mm) is standard for a 160 A frame in the 3VA family — it occupies the same DIN-rail footprint as other 4-pole 3VA breakers in the same frame size, so a panel laid out for a 3VA1112 will accept this unit without moving the rail or drilling new gland-plate holes. Front-face protection is IP40, meaning tools and fingers are kept out but the unit is not sealed against water ingress — mount it in an enclosure rated for the environment. Storage range is -40 °C to 80 °C; operating range is -25 °C to 70 °C. No undervoltage release, no trip indicator, no ground-fault monitoring on this variant — it is a straight thermal-magnetic line-protection breaker.
