Siemens 3VA1132-5EF36-0HH0 — 32 A SENTRON MCCB with 187 kA Interrupting Capacity
The Siemens 3VA1132-5EF36-0HH0 is a 3-pole SENTRON molded case circuit breaker rated for 32 A continuous current at 40 °C ambient, with a breaking capacity of 187 kA at 240 VAC — that's the short-circuit current it can safely interrupt without welding contacts or rupturing the case, which matters when you're coordinating downstream feeders in a high-fault panel. Breaking capacity drops as voltage rises: 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. Thermal rating holds at 32 A from 40 °C through 50 °C, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C. The design is line protection (not motor protection), meaning it's intended for feeder and distribution duty, not overload protection of a motor circuit.
Built-in Accessories and Panel Fit
That's enough status feedback for a PLC input card without adding external relays. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. The storage limit governs shipping and warehouse conditions, not running duty.
