Residual-current circuit breaker 2P C 16A 0.03A Type AC Kanlux KRO6-2/C16/30 (23217)

Kanlux KRO6-2/C16/30 is a 2-pole residual-current circuit breaker combining a miniature circuit breaker (MCB) with a residual current device (RCD). It has a C tripping characteristic and a rated current of 16 A with residual current sensitivity of 0.03 A (30 mA), type AC. The device is intended for installation in domestic and light-commercial distribution boards where combined protection against overload, short-circuit and earth leakage is required. Its compact DIN-rail form factor and integrated design save panel space while providing selective protection for two-pole circuits.

Advantages

The integrated RCD+MCB design provides both overcurrent protection and earth-leakage detection in a single module, simplifying wiring and reducing component count in the distribution board. C characteristic ensures reliable tripping for general-purpose circuits with moderate inrush currents such as lighting and small motor loads. Sensitivity of 30 mA helps protect against dangerous residual currents and reduces the risk of electric shock and fire. The two-pole configuration isolates both line and neutral conductors for improved safety on single-phase circuits.

Suitable for

• Protection of lighting circuits in apartments and houses
• Protection of socket circuits in residential and small commercial premises
• Service circuits with moderate inrush currents such as small motors or pumps
• Upgrading or refurbishing distribution boards to add residual-current protection

Key specifications

• Poles: 2-pole device
• Rated current: 16 A
• Tripping characteristic: C curve
• Residual current sensitivity: 0.03 A (30 mA), Type AC (sinusoidal AC earth-leakage)
• Function: Combined overcurrent (MCB) and residual current (RCD) protection
• Mounting: DIN-rail compatible enclosure

How to use

Install the device on a standard DIN rail inside the distribution board, ensuring power is isolated before any work. Connect the supply and load conductors according to local wiring regulations, with line and neutral conductors connected to the respective terminals for the two poles. Verify correct tightening torque for terminals and ensure neutral continuity where required. After installation, restore power and test the residual-current function using the built-in test button or a suitable RCD tester to confirm operation at the specified sensitivity.

Usage recommendations

Use this residual-current circuit breaker in systems where 30 mA sensitivity is appropriate for human protection and fire risk reduction. Do not use in circuits requiring DC-sensitive protection or selective discrimination with upstream devices without verifying coordination. Periodically test the device (at least every 6–12 months) using the test button and perform professional inspection after any electrical system modification.
