| Design Of The Product | For motor protection |
Ground fault detection is not included, so plan for a separate GFCI or RCD if the installation requires it.
Mounts in any position, screw or snap-on to 35 mm DIN rail. Clearance: 50 mm above and below, 30 mm to the side, zero forwards or backwards — so it tucks tight against the backplane. That's a solid grip for motor feeders up to the rated current — no screw torquing needed, just strip and push.
Depth is 97 mm, width is 45 mm — standard single-module width for SIRIUS breakers, fits a 45 mm DIN-rail slot.
