That flat thermal curve means you can size it for a 800 A bus without over-speccing for a warm panel. The 187 kA breaking capacity at 240 V, 121 kA at 415 V, and 53 kA at 690 V covers high-fault installations like transformer secondaries or large motor control centers where upstream coordination demands a stiff interrupt rating. The ETU860 electronic trip unit gives you adjustable long-time (Ir up to 800 A, tr 0.5–25 s) and short-time (tsd 0.05–0.5 s) protection, plus ground-fault summation monitoring on the L conductors — useful for detecting leakage on ungrounded or resistance-grounded systems. It's a line-protection variant, so no N-conductor protection built in; you'd add a separate neutral sensor if needed. The 210 mm width and 320 mm height fit a standard MCCB footprint; depth is 120 mm. ## Deployment context This MCCB mounts in a panel on a standard mounting plate or DIN-rail adapter (not included). The communication function enables remote trip indication, current monitoring, and parameter adjustment via a communication module for PROFIBUS, PROFINET, or Modbus. The 10 000 latching endurance cycles is the mechanical life.","metaTitle":"Siemens 3VA2580-5KQ32-0LL0 SENTRON MCCB, 800 A, 3-Pole, ETU8","metaDescription":"Siemens 3VA2580-5KQ32-0LL0 SENTRON molded case circuit breaker, 800 A, 3-pole, ETU860 release, 187 kA at 240 V.
