Hager ADC225T 25 Amps 1 Pole RCBO Safety Switch 6kA 30mA Type A C Curve 1 Module DIN Rail 230-240V

Description

25 A single pole RCBO in one module.

The Hager ADC225T combines overload, short circuit and earth leakage protection for a 25 A final circuit in a single 17.8 mm module. It adds full RCBO protection to an existing board without claiming a second module of rail.

Combined Protection, Single Module

One ADC225T does the work of a separate MCB and RCD, guarding a 25 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.

25 A for General Final Circuits

The 25 A C curve rating suits general final subcircuits: mixed power and lighting, larger socket circuits and heating loads without heavy start-up surge. The C curve tolerates the ordinary inrush of everyday equipment while still 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, LED drivers, inverters and speed controllers spread through Australian homes and workplaces, Type A has become the practical baseline for final subcircuit protection. The ADC225T 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: 25 A at 30 °C ambient, 23.35 A at 40 °C and 20.05 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 ADC225T 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 the same 25 A rating, look at the 1P+N Hager ADC925T.

Q: What does the Type A rating on the ADC225T mean?
A: Type A means the RCBO responds to sinusoidal AC residual currents and to pulsating DC residual currents, unlike a Type AC device which responds only to the AC component. It has a rated residual operating current of 30 mA.

Q: What cable sizes do the ADC225T 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.
