## Summary description

Eti-Polam KZS-4M is a combined residual-current and overcurrent protection device (RCBO) with 4 poles, rated current 32 A, C tripping characteristic and 30 mA residual current sensitivity (type AC). Designed to provide simultaneous short-circuit/overload and earth-leakage protection for residential and light commercial electrical circuits.

## Long description

Eti-Polam KZS-4M 4P 32A C 30mA type AC is a combined residual-current circuit breaker with integrated overcurrent protection (RCBO) designed for residential and light commercial electrical installations. This four-pole device provides simultaneous protection against short circuits, overloads and earth-leakage currents, with a rated current of 32 A, C-type tripping characteristic and 30 mA residual current sensitivity suitable for general protection of circuits where AC leakage detection is required.
Advantages
The RCBO combines two protection functions in one compact unit, reducing the need for separate miniature circuit breakers and residual current devices and saving distribution board space. The C tripping characteristic ensures reliable performance for circuits with moderate inrush currents, while the 30 mA sensitivity provides personal protection against electric shock from AC leakage currents. Four-pole construction allows protection of three-phase circuits including neutral, simplifying wiring and coordination in multi-phase installations.
Suitable for
Protection of three-phase and four-wire circuits in homes and small commercial premises
Final circuits for power outlets, lighting and small motors with moderate inrush currents
Coordinated protection in distribution boards where combined overload and earth-fault protection is required
Key specifications
Number of poles: 4
Rated current: 32 A
Tripping characteristic: C (suitable for moderate inrush currents)
Residual current sensitivity: 30 mA, type AC (detects AC leakage currents)
Function: combined overcurrent (short-circuit/overload) and residual-current protection
How to use
Install the RCBO in the distribution board on a compatible DIN rail following local electrical codes and the manufacturer's mounting instructions. Connect the three phase conductors and neutral to the corresponding terminals, and the load-side conductors to the output terminals. Ensure the supply is isolated before making connections. After wiring, perform insulation and continuity tests and verify correct operation by using the device test button or a suitable RCD tester to simulate leakage and confirm trip behavior at 30 mA.
Usage recommendations
Use this RCBO in circuits where combined protection is preferable to separate devices, and select the C characteristic and 32 A rating to match expected load and inrush conditions. Regularly test residual-current operation using the integrated test button or dedicated test equipment and perform periodic inspection as part of routine electrical maintenance.
