Motor protection breaker for panel integration
Breaking capacity reaches 100 kA at 240 V, 400 V, and 500 V, dropping to 2 kA at 690 V. Any mounting position is permitted, which simplifies layout in a crowded enclosure. No ground-fault detection on this variant, so if that's required, a separate module or a different order code is needed.
The depth is the critical dimension for enclosure depth clearance — 75 mm from the DIN rail face to the back of the breaker. Clearance requirements: 20 mm upward and downward, 9 mm to the side, 0 mm forward or backward — so you can butt it against the back panel or adjacent devices with zero gap. Main circuit terminals are M3 screw-type, accepting 2×(0.5…1.5 mm²) or 2×(0.75…2.5 mm²) solid or stranded wire. No special ferrules required for the stranded sizes within range. For back-up protection at 400 V, the manufacturer specifies a gL/gG 20 A fuse — this is the maximum fuse rating that preserves the breaker's interrupting rating.
