Circuit breaker 3VM1132-5EE42-0AA0 — key ratings and fit
The Siemens 3VM1132-5EE42-0AA0 is a 4-pole IEC frame 160 circuit breaker rated at 32 A with a breaking capacity of 55 kA at 415 V (class M). The TM220 ATFM thermal-magnetic trip unit provides overload protection adjustable from 22 A to 32 A and fixed short-circuit protection at 10 × In. This is a line-protection device, not a motor-protection breaker — the thermal curve is sized for cable and busbar protection, not for motor overload class. The 55 kA Icu at 415 V means this breaker safely interrupts fault currents up to that level without welding or rupturing, per IEC 60947-2. For a 415 V distribution panel with a high available fault current, that rating avoids cascading failure upstream. The 4-pole configuration with unprotected N conductor suits 3-phase + neutral systems where the neutral is not switched — verify your system's neutral switching requirement before specifying.
Lifecycle and sourcing posture
This part carries an active lifecycle status per the manufacturer. It is classified as Product class C: manufactured or produced to order, which means it is not a stocked shelf item — each unit is built against a confirmed order and cannot be returned for credit. Plan your lead time accordingly; this is not a same-day ship line item.
Panel integration note
The 3VM1 frame 160 mounts on a DIN rail or panel-mount plate. Packaging dimensions are 150 × 119 × 116 mm — confirm gland-plate clearance and side-to-side spacing for heat dissipation at full rated current. The nut keeper kit is included for secure panel-mount installation.
