Residual-current circuit breaker with overcurrent module VCX GACIA SL6N 2P B 16A 30mA 1P+N Type AC

VCX GACIA SL6N 2P B 16A 30mA 1P+N Type AC is a residual-current circuit breaker with an integrated overcurrent module designed for combined earth-fault detection and overload/short-circuit protection in single-phase installations. Configured as a 2-pole device (1P+N) with B characteristic, rated current 16 A and residual operating current 30 mA, it is suitable for protecting circuits against leakage currents while ensuring reliable disconnection under overload conditions. The Type AC detection ensures responsiveness to standard alternating residual currents commonly found in residential and light commercial environments.

Advantages

The unit combines residual-current detection and overcurrent protection in a compact two-pole format, reducing the need for separate devices and simplifying distribution board layout. Its B characteristic provides a balance between sensitivity to short-circuit currents and selectivity for downstream devices often used in household circuits. A rated residual operating current of 30 mA offers personal protection against indirect contact, while the 16 A rated current matches common lighting and socket branch circuits. The Type AC sensing ensures dependable operation for sinusoidal AC leakage currents.

Suitable for

• Protection of single-phase lighting and socket circuits in residential buildings
• Use in light commercial installations and small offices
• Retrofit projects where space in the distribution board is limited
• Circuits requiring combined earth-fault and overcurrent protection

Key specifications

• Configuration: 2-pole (1P+N)
• Rated current: 16 A
• Residual operating current (sensitivity): 30 mA
• Tripping characteristic: B (overcurrent module)
• Residual-current type: AC (sensitive to alternating leakage currents)

How to use

Install the device in the consumer unit on a standard DIN rail according to local wiring regulations and manufacturer instructions. Connect the phase conductor to the live terminal and the neutral conductor to the neutral terminal; ensure correct orientation so that the device monitors both conductors as intended. Use appropriate cable cross-sections and tighten terminals to the recommended torque values. Verify upstream and downstream coordination with other protective devices in the installation. After wiring, perform functional and trip testing to confirm correct operation of both residual-current and overcurrent functions before putting the circuit into regular service.

Usage recommendations

Select this residual-current circuit breaker with overcurrent module for circuits where combined protection is required and where Type AC sensitivity is sufficient. For circuits with electronic equipment that may generate pulsating DC leakage currents, consider checking compatibility with Type A or other appropriate residual-current types. Schedule periodic testing of the trip function and visual inspection during maintenance to ensure ongoing protection performance.
