Circuit breaker EATON Kombiafbryder 1-pole + neutral 16A C-characteristic 6 kA 300 mA Class A

EATON Kombiafbryder 1-pole + neutral 16A C-characteristic 6 kA 300 mA Class A is a combined residual-current device (RCD) and miniature circuit breaker (MCB) designed for protection of distribution circuits in residential and light-commercial installations. The unit integrates overcurrent and earth-leakage detection in a single compact module with one pole plus neutral configuration, a C tripping curve for general-purpose circuits, a rated current of 16 A and a residual current sensitivity of 300 mA (Class A). The device has a rated short-circuit breaking capacity of 6 kA, suitable for typical consumer mains and sub-distribution boards.

Advantages

The combined design reduces panel space by integrating overcurrent and residual-current protection into one device, simplifying wiring and installation. With a C-characteristic tripping curve, the device balances protection of cables and equipment against nuisance trips from moderate inrush currents. The 300 mA residual-current sensitivity provides additional protection against persistent earth faults and reduces the risk of fire caused by insulation faults in circuits. The 6 kA breaking capacity ensures reliable interruption of fault currents within the typical range for domestic and light-commercial supply networks.

Suitable for

• Protection of lighting and socket circuits in homes and apartments
• Feeders and sub-circuits in small commercial installations
• Circuits where both overcurrent and earth-leakage protection are required but panel space is limited

Key specifications

• Number of poles: 1 pole + neutral
• Rated current: 16 A
• Tripping characteristic: C curve
• Residual current sensitivity: 300 mA (Class A)
• Short-circuit breaking capacity: 6 kA
• Device type: Combined RCD + MCB

How to use

Install the device on a standard DIN rail inside a distribution board, ensuring correct orientation and secure connection of phase and neutral conductors to the marked terminals. Verify that the supply is isolated before making connections. After wiring, test the residual-current function and breaker trip operation according to local wiring regulations and manufacturer instructions. Use the device in circuits not exceeding the rated current and ensure coordination with upstream and downstream protective devices where applicable.

Usage recommendations

Use this combined breaker for circuits where both overload/short-circuit protection and earth-leakage detection are required but a selective low-level RCD is not necessary. Regularly test the residual-current function and inspect connections for signs of overheating; replace the device if tripping behaviour becomes unreliable or if physical damage is observed.
