The rated voltage range spans 20 to 690 V, covering common low-voltage motor circuits from 24 V control transformers to 480/600 V line feeds. Breaking capacity is 100 kA at 240 V, 400 V, and 500 V, dropping to 2 kA at 690 V. On a 400 V line this holds the full fault current available from a typical 1 MVA transformer — no upstream fuse needed for short-circuit coordination in most panel designs.
Any mounting position allowed. Dimensions: 45 mm wide, 90 mm tall, 75 mm deep. Clearance requirements: 20 mm above and below, 9 mm to the side, zero forward or backward clearance needed. Main circuit terminals are screw-type, accepting 2×(0.5 to 1.5 mm²) or 2×(0.75 to 2.5 mm²) solid or stranded copper. Torque to M3 screw size. No ground-fault detection — this is a motor-protection-only device, not a GFCI.
