SENTRON 3VA1116-5ED32-0AA0 — 160 A MCCB for Line Protection
The Siemens 3VA1116-5ED32-0AA0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels and industrial switchboards. It carries a 160 A continuous rating at 40 °C ambient, with a 3-pole configuration and a TM210 thermal-magnetic overcurrent release that handles both overload and short-circuit conditions without external trip units. Breaking capacity is the headline spec here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That high interrupt rating at 240 V makes this breaker a strong candidate for high-fault service entrance or sub-distribution where available short-circuit current exceeds 100 kA — common in large industrial plants or utility tie points. Current derating is published across the full ambient range: 160 A up to 50 °C, then 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. If the panel runs hot — say near a furnace line or in a non-conditioned enclosure — the 150 A floor at 70 °C still gives headroom for a 150 A feeder without nuisance tripping.
Physical Fit and Panel Integration
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that drops into SENTRON 3VA mounting bases and busbar adapters without modification. The IP40 front protection means it is suited for enclosed panel mounting where the front face is behind a door; not rated for washdown or outdoor exposure. No undervoltage release, no ground-fault monitoring module, and no communication function are integrated on this variant. If those are needed for the application, they must be added externally via the 3VA accessory system — the breaker itself is a straight thermal-magnetic line-protection device.
