It protects a single-phase outgoing circuit against overload, short-circuit, and earth leakage, with a rated current of 40 A at 50 °C and an earth-leakage sensitivity of 30 mA. Torque the top connection to 3.5 N·m and the bottom to 2 N·m.
For a buyer sourcing this part, the paperwork is straightforward: the standards compliance covers most global markets, and the part carries the Schneider Electric brand with full traceability.
Integration notes
The module occupies 2 x 9 mm pitches (18 mm total width) on a DIN rail. Depth is 77.5 mm, height 110 mm. The toggle actuator provides ON/OFF local signalling and is padlockable with a 4 mm diameter padlock for lockout/tagout. The electrical durability is rated at 5,000 cycles, mechanical durability at 20,000 cycles — figures that reflect a typical panel-mounted distribution device rather than a high-cycling motor-switching role. The limitation class is 3, which limits let-through energy under fault conditions.
