The breaking capacity is the headline number here: 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V. The electronic trip unit is an ETU860 — a fully programmable, communicating release that supports adjustable long-time (Ir from 0.5× to 1× Iu, tr from 0.5 to 25 s), short-time (Isd and tsd down to 0.05 s), and instantaneous protection. It also includes ground-fault monitoring via summation current formation on the line conductors. The communication function and other measurement functions are built in, meaning this breaker can feed power-quality data back to a BMS or PLC without an external meter. It is designed for panel mounting, not DIN-rail snap-on. ## What it does not include The product version is line protection only — no N-conductor protection is built in (the design is without N protection). That is typical for a 3-pole breaker on a 3-wire delta system; if you need 4-pole or neutral protection, this is not the variant.","metaTitle":"Siemens 3VA2580-5KQ32-0JH0 SENTRON MCCB, 800 A, 3-Pole, ETU8","metaDescription":"Siemens SENTRON 3VA2580-5KQ32-0JH0 molded case circuit breaker, 800 A continuous, 3-pole line protection with ETU860 electronic trip unit.
