That thermal curve means this breaker handles high-ambient panels without oversizing the frame, a common pain point in packed switchgear. Interrupting capacity is 187 kA at 240 V, stepping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 52.5 kA at 690 V. For a 3-pole line-protection breaker, those numbers give selectivity headroom downstream — you can coordinate with smaller branch breakers without worrying about cascading faults through the main. That config saves panel-build time — no separate add-on modules to order and snap in. Dimensions are 320 mm height, 210 mm width, 120 mm depth — a standard MCCB footprint for the 800 A frame class. The 3-pole design with line-protection trip curve fits into a distribution panel or motor control center as a main or large feeder breaker. Rated insulation voltage is 800 V, with operating temperature range from -25 °C to 70 °C and storage from -40 °C to 80 °C. The trip indicator and undervoltage release are factory-integrated, so no field wiring of separate accessories.","metaTitle":"Siemens 3VA1580-5EF32-0DL0 SENTRON MCCB, 800 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1580-5EF32-0DL0 molded case circuit breaker, 800 A at 40 °C, 3-pole, 187 kA interrupting at 240 V.
