        Hager | RCBO 25A 1P+N 6kA ADC9 | C Curve 30mA Type A

        The Hager ADC925T is a single-module RCBO rated 25A, combining overcurrent protection and 30mA residual current detection in one DIN-rail device. The ADC925T is a single pole and neutral (1P+N) unit with a 6kA breaking capacity, a C curve trip characteristic, and Type A earth leakage sensing. It complies with AS/NZS 61009 and occupies a single module on a switchboard or sub-board.

        Switchboard space runs out fast when a board needs extra circuits added during a renovation or a shed wiring job. The ADC925T fits a full RCBO into a single 18mm module, so it drops into the space of one MCB without widening the board. Because both line and load terminals are non-sensitive, the unit can replace another brand without rewiring the circuit. The reduced height also leaves extra wiring space in the enclosure for a tidier board build.

        For contractors populating a board, the ADC925T saves time on every pole. The factory-fitted neutral fly lead means one less conductor to land, and the built-in fault trip indicator shows whether a trip came from an overload or an earth fault. Insulation resistance testing runs faster because outgoing conductors stay connected. Stocking one slimline RCBO that replaces a standard MCB also simplifies the van and the board layout.

        Features

        • 25A rated current — the ADC925T carries a 25A load on a single final subcircuit, suited to higher-draw domestic and light commercial circuits.
        • Single module width — the RCBO occupies one 18mm DIN module, taking the space of a standard MCB on the busbar.
        • 1P+N switching — switches both active and neutral, fully isolating the circuit for safe maintenance and for switched-neutral applications.
        • 30mA Type A earth leakage — detects AC and pulsating DC residual current, the sensitivity required for circuits feeding electronic loads.
        • C curve trip characteristic — handles normal inrush from general power and lighting circuits without nuisance tripping.
        • 6kA breaking capacity — interrupts fault currents up to 6kA, matching typical domestic and light commercial prospective short-circuit levels.
        • Factory-fitted neutral fly lead — a 1 metre neutral tail is preconnected, leaving one less conductor to terminate during board assembly.
        • Bi-connect terminals — accept supply from either a cable in the cage or a fork busbar in the slot, giving full connection flexibility.
        • Built-in trip indicator — a front flag identifies whether the device last tripped on overload or on residual current, speeding fault diagnosis.
        • Non-sensitive terminals — line and load are not fixed, so the ADC925T can replace another brand without rewiring the circuit.
        • AS/NZS 61009 compliant — certified to the combined RCBO standard for installation under the AS/NZS 3000 wiring rules.
        • Type A RCD limit — the device does not detect smooth DC fault current and is not a substitute for a Type B RCD on those loads.

        Where to use

        • Domestic switchboard upgrades — the ADC925T adds RCD and overcurrent protection to a final subcircuit where board space is limited.
        • MCB replacement — drops into the width of an existing MCB to bring an older circuit up to current RCD requirements.
        • Shed and outbuilding boards — protects power and lighting circuits in detached structures running off a sub-board.
        • Caravans and transportable structures — the switched-neutral design suits demountables, motorhomes, and relocatable buildings.
        • Construction site temporary boards — provides individual circuit protection on sites where switched neutral is specified.
        • Solar PV circuits — Type A switched-neutral protection suits single-phase inverter connections run behind the building surface.
        • EV charging circuits — the ADC925T protects a charging point requiring at least Type A 30mA RCD protection.

        The ADC925T is a Type A RCBO and is not rated for smooth DC fault current from loads such as some three-phase EV chargers and variable speed drives. It is a DIN-rail device for enclosed switchboards and is not suitable for direct outdoor or exposed mounting without a rated enclosure. Its 30mA sensitivity is not the 10mA level specified for cardiac-protected patient areas.

        Verified Sparky Direct customer reviews: HAGER ADC925T | RCBO 25Amp 1P&N 6kA C Curve 30mA Type A (ADC925T)

        "preinstalled neutral tail makes installation quick and easy" — Peter

        "Easy to fit in the board" — Victor

        "gives an indication if the trip was over current or earth leakage" — Omar

        (ADC925T)

        The Hager ADC925T is certified to AS/NZS 61009, the combined standard for RCBOs. It provides Type A residual current detection at 30mA, the sensitivity the AS/NZS 3000 wiring rules call for on circuits feeding electronic equipment. Installation must follow the wiring rules and be carried out by a licensed electrician.

        Installation must be carried out by a licensed electrician. The RCBO clips onto a standard DIN rail and takes a single 18mm module. A factory-fitted 1 metre neutral fly lead connects to the neutral bar, leaving the active and load terminals to land in the board.

        The 1P+N rating means the device switches both the active and the neutral of a single-phase circuit. Full isolation suits switched-neutral applications such as caravans, construction boards, solar, and EV charging. The active pole carries the 25A overcurrent protection, and both poles open on a fault.

        The compact single-module body takes the space of one MCB, so it can replace a circuit breaker to add RCD protection. Because the line and load terminals are non-sensitive, no rewiring of the circuit is needed when swapping from another brand. Confirm busbar and enclosure fit before installing.

        The bi-connect terminals accept supply from either a cable in the terminal cage or a fork busbar in the slot. Single-phase and three-phase Hager fork busbars suit a board populated with these single-module RCBOs. The bi-stable DIN clip lets one unit be removed without disturbing the others on the busbar.

        The warranty runs one year for domestic use and one year for commercial use, starting from the invoice date, handled as return to Sparky Direct. Warranties are void if the product is not installed by a licensed electrician. Keep proof of purchase to support any claim.

        A Type A device detects AC and pulsating DC residual current, which covers most domestic and light commercial circuits. It does not detect smooth DC fault current, so loads that can produce it, such as some three-phase EV chargers and variable speed drives, need a Type B RCD. Check the load type against AS/NZS 3000.
