What the 160 A rating and breaking capacity mean for your panel
The 3VA1116-6ED32-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated 160 A continuous at 40 °C, with a TM210 thermal-magnetic release — so the thermal element handles overloads and the magnetic element clears short-circuits. That 160 A holds steady across 40–50 °C ambient, then derates to 150 A at 70 °C; if your panel runs hot near the top of a sealed enclosure, you lose 10 A off the top end. The breaking capacity is what sets this MCCB apart for high-fault installations: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500/690 V. That 220 kA figure at 240 V means it can interrupt a fault current that would vaporize a standard 65 kA breaker — sized for transformer secondaries or large motor control centers where available fault current is extreme.
Panel fit and mounting — 3-pole, 70 mm deep, IP40 front
Three-pole construction, 76.2 mm wide, 130 mm tall, and 70 mm deep — that depth is the dimension from the mounting surface to the front, so it clears a standard 80 mm deep enclosure without door interference. The front face carries IP40 protection, meaning tools or fingers won't reach live parts, but it is not sealed against dust ingress; keep it inside a panel, not on a washdown wall. Rated insulation voltage is 800 V, so it can sit on a 690 V bus without de-rating the insulation coordination.
Power loss and thermal management — 38 W at rated load
Maximum power loss is 38 W at rated current — that heat has to go somewhere inside the enclosure. In a multi-breaker panel, sum the losses and check the enclosure's dissipation curve; 38 W per MCCB adds up fast in a 12-way distribution board.
No communication, no trip indicator, no undervoltage release — pure line protection
This variant is stripped for basic line protection: no communication function, no undervoltage release, no trip indicator, no ground-fault monitoring. The TM210 release is a thermal-magnetic type — no electronic adjustment, no zone-selective interlocking. If you need remote signaling or adjustable trip curves, look at the 3VA electronic-trip variants; this one is for fixed-threshold, hardwired distribution where simplicity and high interrupting capacity are the priority.
