Rated current and interrupting capacity — what they mean for your panel
The Siemens SENTRON 3VA1116-3ED36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous at 40 °C ambient, with the TM210 thermal-magnetic release providing line protection. That 160 A holds flat through 50 °C — only drops to 158 A at 55 °C and 150 A at 70 °C — so in a warm enclosure you still get nearly full rating without derating the breaker itself. The interrupting capacity tells you where it can sit in the fault-current hierarchy: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. That means at 415 V common in European industrial panels it clears a 52.5 kA fault without upstream fuses; at 690 V the 11.9 kA still covers most motor-drive branch circuits.
Physical fit and panel integration
The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most DIN-rail or panel-mount assemblies without re-drilling. The front face carries IP40 protection, so it's fine in a clean indoor panel but not for washdown areas. Maximum power loss is 38 W at rated load, which matters for enclosure thermal calculations if you're stacking several breakers in a sealed cabinet.
Approvals and compliance documentation
As a Siemens SENTRON product, this MCCB carries the usual suite of compliance documentation — RoHS, REACH, UL, IEC — though specific cert numbers are not listed in the spec record. The insulation voltage is rated at 800 V, and the storage temperature range spans -40 °C to 80 °C, exceeding the operating range of -25 °C to 70 °C.
