The 3VM1132-5EE36-0AA2 is a Siemens 3VM1 IEC frame 160 molded case circuit breaker, 3-pole, with a 55 kA breaking capacity at 415 V (class M). The thermal-magnetic trip unit (TM220, ATFM) gives adjustable overload protection from 22 A to 32 A, so you set the Ir dial to match your load's full-load amps, and a fixed magnetic short-circuit pickup at 10 x In (320 A) for instantaneous clearing on hard faults.
Deployment context
The terminal connection style accepts standard lug or busbar, common in distribution boards and motor control centers where you need coordinated short-circuit protection downstream of a main breaker.
