The Siemens SENTRON 3VA1080-4ED42-0HA0 is a 4-pole molded case circuit breaker (MCCB) rated for 80 A continuous current, with a TM210 thermal-magnetic overcurrent release. It is configured for line protection — no ground-fault monitoring, no auxiliary contacts, no communication function. The interrupting ratings are 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V, which means it can clear high-fault currents at common distribution voltages without upstream coordination issues. The front face carries IP40 protection, suitable for enclosed panel mounting.
The 3VA1080-4ED42-0HA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. The 4-pole footprint matches standard Siemens 3VA panel cutouts and busbar layouts. It accepts a shunt trip release (order code 3VA9688-0BL30) if remote tripping is needed. No undervoltage release or auxiliary contact module is fitted as shipped — those are add-on accessories. The TM210 release is fixed thermal-magnetic, not electronic, so coordination curves are set at the factory; no field programming required.
Compared to the 3VA1010-2ED32-0JA0, this 3VA1080-4ED42-0HA0 is a higher-current frame (80 A) and carries a 4-pole configuration instead of 3-pole. The 3VA1010-2ED32-0JA0 uses a different release and has a smaller interrupting capacity at equivalent voltages. Panel cutouts differ — the 3VA1080 frame is physically larger, so a direct drop-in without rewiring is not possible.
