Insulation voltage rated 800 V. Current rating holds flat at 32 A from 40 °C through 50 °C, then drops to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. That's a 6.25% derating from 50 °C to 70 °C — predictable and linear enough to factor into a panel thermal budget. Maximum power loss is 10.6 W per pole, so total dissipation across three poles is roughly 32 W at full load. ## Auxiliary switching and configuration This variant ships with two factory-installed high-performance auxiliary switches (designated HP). The supplied basic switch order code is 3VA11324EF360AA0.","metaTitle":"Siemens 3VA1132-4EF36-0AB0 SENTRON MCCB, 32 A, 3-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1132-4EF36-0AB0 molded case circuit breaker, 32 A rated at 40 °C, 3-pole, 121 kA breaking capacity at 240 V.
