80 A MCCB with 187 kA interrupting capacity — selectivity headroom for distribution panels
The Siemens SENTRON 3VA1180-5GD46-0AA0 is a 4-pole molded case circuit breaker rated 80 A continuous current (Iu) at 40 °C, with a TM210 thermal-magnetic release. Its interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 440 V — enough headroom to coordinate selectively with downstream branch breakers in high-fault industrial distribution. Rated insulation voltage Ui is 800 V, and the breaker carries a full thermal derating curve from 80 A at 40 °C down to 74 A at 70 °C. Power loss maxes at 19.2 W.
Sourcing and lifecycle — active line, quoted to order
No official successor or replacement has been issued; the 3VA1 platform remains the current SENTRON molded-case offering.
Dimensions are 101.6 mm wide, 130 mm tall, 70 mm deep — a 4-pole MCCB that fits standard distribution panel mounting. The TM210 release is fixed thermal-magnetic (no electronic trip unit), so no auxiliary power or programming is needed. N-conductor protection is rated at 100 % (full-rated neutral).
