Hager ADM416T RCBO Safety Switch 16A 4 Pole (3P+N) 6kA C Curve 30mA Type A 230-415V 4 Module DIN Rail

Description

Three-phase circuit protection in one compact device.

The Hager ADM416T is a 16A, 4 pole (3P+N) RCBO that combines overload, short-circuit and 30mA earth leakage protection in a single 4 module DIN rail unit. It removes the need for a separate RCD and MCB on each three-phase final subcircuit, saving switchboard space and wiring time.

Why a 4 Pole RCBO Matters in Three-Phase Boards

One device, three protection functions
An RCBO (residual current breaker with overcurrent protection) is an MCB and an RCD built into one device. The ADM416T trips on sustained overload through its thermal element, on short-circuit through its magnetic element, and on earth leakage at 30mA. Because each three-phase circuit gets its own residual current protection, a fault on one circuit does not take down others sharing a common RCD.

Type A detection and C curve performance
Type A residual current detection responds to AC and pulsating DC earth fault currents. The C curve suits mixed and moderately inductive loads where short inrush currents occur at switch-on. With a 6kA rated breaking capacity and I²t energy limitation class 3, the ADM416T is built for Hager's stated application: residential and light commercial distribution boards.

Planning your installation

• Derating applies above 30°C: 16A at 30°C, 15.2A at 40°C and 13.6A at 60°C.
• Apply a 0.80 correction factor when two devices are mounted side by side.
• Terminals accept flexible conductors 1-16mm² and solid conductors 1-25mm², tightened to 2Nm.
• Installation must be carried out by a licensed electrician in accordance with AS/NZS 3000 Wiring Rules.

Q: What is the difference between the Hager ADM416T and a standard 4 pole MCB?
A: A standard MCB only protects against overload and short-circuit. The ADM416T adds 30mA Type A earth leakage protection, so it acts as both a circuit breaker and a safety switch in one 4 module device.

Q: How wide is the Hager ADM416T RCBO?
A: It occupies 4 DIN rail modules, measuring 71mm wide, 84mm high and 70mm deep, with the neutral pole on the right-hand side.

Q: Can accessories be added to the Hager ADM416T?
A: Yes. Hager lists optional accessories for this RCBO, including auxiliary and alarm contacts (MZ201, MZ202), shunt trips (MZ203, MZ204), an undervoltage release (MZ206), a padlockable locking kit (MZN175) and modular busbars.
