A 415 V panel with a prospective fault current of 100 kA sits well inside the 154 kA ceiling, so the breaker clears without upstream devices needing to operate. At 690 V the 17 kA rating is lower; if your installation has a high-fault 690 V bus, verify coordination upstream. ## Thermal derating — the current curve matters for enclosed panels The breaker holds 32 A continuously up to 50 °C ambient. Above that it derates: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If the MCCB is mounted in a sealed enclosure with heat buildup, use the 55 °C or 60 °C figure for your load calculation — not the 32 A nameplate. ## Auxiliary contacts and integrated trip — what ships on the breaker A shunt trip (STL) is integrated as the auxiliary release — no separate undervoltage release is present. The front face carries a trip indicator and a voltage trigger; communication function and phase failure detection are not included. Protection class on the front is IP40 — suitable for panel interiors, not washdown environments.","metaTitle":"Siemens 3VA1132-6EF32-0JH0 SENTRON MCCB, 32 A, 3-Pole, 220 k","metaDescription":"Siemens 3VA1132-6EF32-0JH0 SENTRON molded case circuit breaker, 32 A, 3-pole, TM240 release, 220 kA breaking capacity at 240 V.
