Hager ADA982D Residual Current Circuit Breaker with Overcurrent Protection 2P 32A C 30mA Type A

The Hager ADA982D is a high-performance residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive electrical safety in both residential and commercial environments. This 2-pole device integrates both short-circuit and overload protection with earth leakage detection into a single compact unit, ensuring that electrical circuits remain protected against dangerous faults. Designed for 240V AC systems, it offers a reliable solution for modern electrical distribution boards where space efficiency and high safety standards are required.

Advantages

The primary benefit of the Hager ADA982D is its dual-functionality, which combines the features of a miniature circuit breaker and a residual current device into one streamlined component. By utilizing Type A sensitivity, this device is capable of detecting both AC and pulsating DC residual currents, providing a higher level of protection compared to standard AC-type breakers. Its robust construction ensures long-term operational reliability, while the C-curve tripping characteristic makes it ideal for handling moderate inrush currents commonly found in household appliances and lighting circuits.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of final circuits with sensitive electronic equipment
• General purpose electrical installations requiring earth leakage protection

When it may not be suitable

This device is not intended for use in DC-only electrical systems or industrial environments requiring specialized protection against high-frequency leakage currents. It should not be installed in circuits exceeding its rated current capacity of 32A, as this could lead to nuisance tripping or failure to protect the circuit adequately.

Key specifications

• Rated current: 32A
• Tripping characteristic: C-curve
• Sensitivity: 30mA
• Type: A
• Poles: 2P
• Operating voltage: 240V AC

How to use

The Hager ADA982D must be installed by a qualified electrician in accordance with local electrical regulations and safety standards. It is designed for mounting onto a standard DIN rail within a distribution board. Before installation, ensure the main power supply is disconnected. Connect the phase and neutral conductors to the designated terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the device should be tested using the integrated test button to verify the mechanical operation of the tripping mechanism.

What to consider before purchase

• Verify that the 32A rating matches the requirements of your specific circuit load.
• Ensure the distribution board has sufficient space for a 2-pole RCBO.
• Confirm that the Type A sensitivity is appropriate for the equipment connected to the circuit.
• Check that the supply voltage is compatible with the 240V AC rating.

Usage recommendations

Regularly test the device using the test button at least every six months to ensure the internal mechanism remains functional and provides reliable protection against electrical faults.
