The 4-pole construction lets it switch three phases plus neutral — common for 3-phase 4-wire distribution where you want the neutral switched for isolation. Above 50 °C it starts to pull back: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. If the breaker lives next to a hot transformer or drive in a sealed enclosure, that 70 °C derated figure is the one to wire the load for. ## Auxiliary switching and mechanical endurance This variant ships with 4 HQ auxiliary switches — high-capacity contacts rated for switching control circuits directly without an interposing relay.","metaTitle":"3VA1080-3ED42-0AE0 SENTRON MCCB, 80 A, 4-Pole, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1080-3ED42-0AE0 molded case circuit breaker, 80 A, 4-pole, 75.6 kA at 240 V interrupting capacity.
