The 800 V rated insulation voltage confirms it's built for 480 V or 600 V class panels as well, with the interrupting curve dropping to 121 kA at 415 V and 75.6 kA at 440 V. ## Ratings and so-what That's a thermal curve you can size a feeder against without guessing. No undervoltage release is fitted, so a control-voltage loss will not automatically open the breaker — that is by design for this variant. It is a straightforward line-protection MCCB with the interrupting muscle for high-fault installations. ## Integration and approvals Maximum power loss is 10.6 W — factor that into your panel thermal budget. The insulation voltage rating of 800 V means it meets IEC 60947-2 requirements for use in 480/277 V and 600/347 V systems. No communication function, so no fieldbus wiring needed — this is a pure power distribution device.","metaTitle":"Siemens 3VA1132-5EF32-0JC0 SENTRON MCCB, 32 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1132-5EF32-0JC0 molded case circuit breaker, 32 A, 3-pole, 187 kA interrupting at 240 V.
