Why it Matters

Switches active and neutral, tuned for inrush.
The ADD916T is a 1P+N RCBO – a residual current breaker with overcurrent protection that switches both the active and neutral conductors. It combines the functions of an MCB and an RCD in one module: protecting against overload and short circuit, and disconnecting on a 30mA earth-leakage fault to guard against electric shock. Breaking the neutral as well as the active fully isolates the final circuit for safe working.

D curve and Type A leakage detection.
The D tripping characteristic trips on short circuit at 10 to 20 times rated current, suited to circuits with high inrush – transformers, motors and switch-mode supplies – that would nuisance-trip a standard C-curve device. Its Type A residual sensing detects both AC and pulsating DC earth-leakage currents, covering modern electronic loads, and its 6kA breaking capacity suits the fault levels found in residential and light commercial switchboards.

Built for Australian switchboards.
At one module (17.7mm) wide, 85mm high and 70mm deep, the ADD916T clips onto standard 35mm DIN rail. Terminals take conductors up to 16mm², it is rated IP20 with a 4kV impulse withstand, and it operates from -25°C to 70°C with 20,000 mechanical and 10,000 electrical operations of endurance. It complies with AS/NZS 61009 for RCBOs and suits high-inrush final circuits requiring combined overcurrent and earth-leakage protection.

Q: What does 1P+N mean on the Hager ADD916T?
1P+N means the device protects and switches one active pole plus the neutral, breaking both conductors together to fully isolate the circuit – while still occupying just one DIN module.

Q: What does the D curve mean on the ADD916T?
The D curve trips on short circuit at 10 to 20 times the rated current, suited to high-inrush loads such as transformers and motors that would nuisance-trip a lower B or C curve.

Q: What is the difference between the ADD916T and the C-curve ADC916T?
Both are 16A 1P+N 6kA RCBOs; the ADD916T has a D curve for high-inrush loads, while the ADC916T has a C curve for general-purpose circuits.
