Hager ADM410T 10A 4 Pole RCBO Safety Switch 6kA 30mA Type A C Curve 3 Phase 4 Module DIN Rail

Description

The Hager ADM410T is a 10A 4 Pole (3 phase plus neutral) RCBO that combines overload protection, short-circuit protection and 30mA earth leakage detection for three-phase circuits in a single 4 module DIN rail device.

Built to AS/NZS 61009, this four-pole RCBO unites a C curve miniature circuit breaker with a Type A residual current device so one unit protects a three-phase circuit against overcurrent faults and protects people against electric shock. It is designed for 3 phase (3P+N) final subcircuits and control equipment such as three-phase motors, pumps, HVAC plant and machinery. The Type A residual current element responds to both AC and pulsating DC leakage currents, giving broader coverage than a basic Type AC device as more equipment uses electronic drives and rectified supplies.

Why choose the Hager ADM410T?

A four-pole RCBO delivers both circuit-breaker and safety-switch functions for a complete three-phase circuit in one device, breaking all three phases and the neutral together on a fault. Providing RCD protection at the individual circuit level means an earth leakage fault on one three-phase circuit does not trip other circuits sharing an upstream device. The 10A rating and C curve suit three-phase control and light-load applications, while the 6kA breaking capacity is appropriate for typical commercial and industrial distribution boards.

What is a Type A RCBO?

A Type A residual current device detects sinusoidal AC earth leakage as well as pulsating DC leakage produced by equipment with rectifiers and electronic controls. This broader coverage is increasingly specified for modern three-phase installations that run variable-speed drives and electronic loads. The ADM410T trips on residual currents at its rated 30mA sensitivity, the level associated with personal protection against electric shock.

Installation and wiring

The ADM410T mounts on standard 35mm DIN rail and occupies 4 modules (71mm) of board width. Terminals accept 1-25mm² rigid or 1-16mm² flexible conductors at a nominal tightening torque of 2Nm. The biconnect bypass bottom connection accepts pin-type busbar for combing devices in a three-phase distribution board, and the device supports 360° mounting orientation. All work must be carried out by a licensed electrician in accordance with AS/NZS 3000.

Frequently asked questions

Is the Hager ADM410T suitable for three-phase circuits?
Yes. It is a 4 Pole (3P+N) RCBO designed to protect a three-phase plus neutral circuit, switching and protecting all four poles together.

Does it provide both overload and earth leakage protection?
Yes. It is a combined RCBO, so a single device provides C curve overload and short-circuit protection plus 30mA Type A residual current (earth leakage) protection.

How much board space does the ADM410T occupy?
It is a 4 module device, 71mm wide, mounting on standard 35mm DIN rail.
