The Siemens 3VA1132-4EE36-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 32 A continuous current at 40 °C ambient, with no derating needed up to 50 °C — it holds 32 A flat through that range, then drops only 1 A per 5 °C step to 30 A at 70 °C. That thermal curve means you can load it to nameplate in a warm enclosure without recalculating. Breaking capacity is the real selector here: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Trip unit and protection design
The overcurrent release is a TM220 — thermal-magnetic, fixed thermal and magnetic settings, no electronic adjustment. This is a line-protection design, not a motor-protection or ground-fault variant.
Dimensions: 130 mm height, 76.2 mm width (3 inches — standard 3-pole MCCB footprint), 70 mm depth. Front IP40 rating means tools or fingers won't reach live parts from the front, but the sides and back rely on the panel enclosure for ingress protection.
