Rated insulation voltage Ui is 800 V, and the breaker maintains full 80 A current rating from 40 °C through 50 °C ambient; above that it derates gradually to 72 A at 70 °C. The TM240 release is adjustable for the long-time pick-up, with a maximum delay tr of 1 s — useful for coordinating with downstream branch breakers on motor or feeder circuits. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — the width is a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration.","metaTitle":"Siemens 3VA1180-5EF32-0AF0 SENTRON MCCB, 80 A, 187 kA","metaDescription":"Siemens SENTRON 3VA1180-5EF32-0AF0 molded case circuit breaker, 80 A rated, 187 kA at 240 V, TM240 release, 3-pole line protection.
