At 415 V — the typical three-phase distribution level in much of the world — 32 kA gives you solid selectivity with upstream 63 kA or 100 kA MCCBs in a coordinated panel. The 690 V figure (7.5 kA) matters for wind-turbine or mining applications where the line-to-line voltage steps up. ## Built-in auxiliary and shunt trip That means remote tripping is wired in from the factory, no field kit to install. The auxiliary contacts give you status feedback for a PLC or remote I/O without adding a separate accessory module. Dimensions are 101.6 mm wide, 130 mm tall, 70 mm deep — a standard SENTRON 3VA footprint that drops into the same mounting cutout as other 4-pole 3VA frames.","metaTitle":"Siemens 3VA1080-2ED42-0KH0 SENTRON MCCB, 80 A, 4-Pole, TM210","metaDescription":"Siemens 3VA1080-2ED42-0KH0 SENTRON molded case circuit breaker, 80 A rated continuous current, 4-pole, TM210 thermal-magnetic release, line protection.
