Motor protection circuit breaker for dusty environments
Rated Trip Class 10, it disconnects a stalled motor fast enough to keep windings intact, which matters when a conveyor jams and the line can't wait for a thermal overload to cool down.
Mounting and wiring in a tight panel
The 45 mm width keeps the fill factor tight — you can pack a dozen of these across a 600 mm rail for a multi-motor group. Screw terminals on the main circuit accept 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²) — no ferrule crimping required for the smaller wire. Mounting position is any, so vertical or horizontal rail orientation works. Clearance: 20 mm above and below, 9 mm to the side, zero forward or backward.
Thermal environment and operating limits
The rated operating voltage spans 20 to 690 V, which means it works on 240 V single-phase control transformers as well as 400 V three-phase motor feeds. For fuse backup: at 400 V use gL/gG 20 A; at 690 V step down to gL/gG 16 A. No fuse required at 240 V.
