It combines a circuit breaker and overload relay in one device, providing short-circuit and overload protection for motor circuits. The Class 20 trip curve means it allows a 20-second overload at 600% of the full-load current before tripping — sized for motors with longer starting times like fans or centrifugal pumps. No ground-fault detection on this variant — that's a separate module if needed.
The 70 mm width and 165 mm height fit standard panel layouts; depth is 176 mm, so leave clearance for the screw terminals and wiring. Main circuit terminals accept solid or stranded wire: 2x (2.5 to 16 mm²) for the smaller conductors, and 1x (10 to 70 mm²) for larger feeds. Screw-type terminals are standard — torque to the manufacturer spec during commissioning.
