Hager ADC240T 40 Amps 1 Pole RCBO Safety Switch 6kA 30mA Type A C Curve 1 Module DIN Rail 230-240V

Description

40 A single pole RCBO in one module.

The Hager ADC240T combines overload, short circuit and earth leakage protection for a 40 A final circuit in a single 17.8 mm module. It is the high-current single-pole option in the range, suiting sub-mains and heavy final circuits while taking just one module of DIN rail.

Combined Protection, Single Module

One ADC240T does the work of a separate MCB and RCD, guarding a 40 A circuit against overload, short circuit and earth leakage in just 17.8 mm of DIN rail. Height is 115 mm and depth 70 mm, so it fits standard flush and surface switchboards. The screw top terminal and BIconnect bottom terminal line it up with the rest of a Hager modular assembly for a tidy fit-off.

40 A for Heavy Final Circuits

The 40 A C curve rating is the largest in the single-pole ADC range, suiting sub-mains, dedicated high-current appliance feeds and heavy power circuits. Terminals accept up to 25 mm² solid conductors, matching the cable sizes these circuits typically run. The C curve tolerates the ordinary inrush of everyday equipment while tripping promptly on a genuine overload or short circuit.

Type A Sensing for Electronic Loads

Type A residual current devices detect sinusoidal AC earth leakage and pulsating DC earth leakage; Type AC devices detect only the former. As switch mode power supplies, inverters and speed controllers spread through Australian homes and workplaces, Type A has become the practical baseline for final subcircuit protection. The ADC240T trips at 30 mA residual current.

Rated for Australian Conditions

Rated operational voltage is 230 - 240 V at 50 - 60 Hz, matching the Australian supply. Hager publishes a full derating curve: 40 A at 30 °C ambient, 38.30 A at 40 °C and 34.90 A at 60 °C, which matters in roof spaces, plant rooms and unventilated meter boxes where board temperatures climb past nameplate assumptions. Storage and transport range is -40 to 70 °C, and the device is rated to 2000 m altitude.

Q: Is the Hager ADC240T single pole or 1P+N?
A: It is a 1 pole device with one protected pole in a single 17.8 mm module, protecting the active conductor. If you need neutral switching at 40 A, look at the 1P+N Hager ADA940T (2 module).

Q: What is the breaking capacity of the ADC240T?
A: It has a rated short circuit breaking capacity of 6 kA (Icn, IEC 60898-1), suited to residential and light commercial final circuits where the prospective fault current is within 6 kA.

Q: What cable sizes do the ADC240T terminals take?
A: The combined input and output screw terminals accept 1 - 25 mm² solid or 1 - 16 mm² flexible conductors. The input only screw terminal accepts 1 - 16 mm² solid or 1 - 10 mm² flexible.
