Product details

The Type B trip curve means it clears overcurrents fast enough for general-purpose socket and lighting circuits, but with enough inrush headroom to avoid nuisance tripping on small motor or capacitive loads.

Tightening torque for the power circuit connections is 2 N.m. IP20 rated — intended for enclosure installation, not washdown areas.

Rated current is 45 A at 50 °C, so no derating is needed for a typical 40 °C panel ambient. The device is padlockable (Ø 4 mm padlock) for lockout/tagout. Local ON/OFF indication and a contact position indicator are provided.

Frequently asked questions

What is the A9D37845 used for?

It is a combined RCBO (residual current breaker with overcurrent protection) for protecting a 1P+N final subcircuit against overload, short-circuit, and earth leakage in TN systems.

What are the key ratings of the A9D37845?

Rated current 45 A at 50 °C, breaking capacity 10 kA at 230 V AC, earth leakage sensitivity 30 mA, Type B curve, 1P+N poles.

Where can I buy the A9D37845?

The A9D37845 is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
