The 4-pole construction handles three-phase plus neutral (or switched neutral) in a single enclosure, saving a pole space versus separate breakers. ## Derating and thermal limits — the real-world current rating The 125 A rating holds flat from 40 °C to 50 °C ambient, then steps down: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. For a panel OEM packing breakers into a confined enclosure, this derating curve governs the actual load you can protect — if the internal panel ambient hits 60 °C, you lose 5 A of headroom. The TM240 release is a fixed thermal-magnetic type; no electronic adjustment or communication module is fitted. Latching endurance is rated at 15,000 operations, which covers frequent switching in machine-tool or conveyor applications.","metaTitle":"Siemens 3VA1132-5EE36-0AB0 SENTRON MCCB, 125 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1132-5EE36-0AB0 molded case circuit breaker, 125 A continuous, 4-pole, TM240 release, 187 kA SCCR at 240 VAC.
