## Summary description

Eti-Polam KZS-2M is a 2-pole residual-current overcurrent circuit breaker combining overcurrent protection (B characteristic, 20 A) with residual current detection (30 mA, type AC). Designed for electrical safety in residential and small commercial installations, it trips on overload/short-circuit and earth-leakage AC currents to prevent fire and electric shock.

## Long description

The Eti-Polam KZS-2M 2P 20A B 0.03A Type AC is a combined residual-current and overcurrent circuit breaker designed for residential and small commercial electrical installations. This two-pole device provides overcurrent protection with a B characteristic rated at 20 A and residual-current detection at 30 mA (type AC), tripping on AC earth-leakage currents. It is intended to reduce the risk of electric shock and fire by interrupting supply during overloads, short circuits and alternating-current leakage to earth.
Advantages
The unit combines both short-circuit/overload protection and residual-current detection in a single module, saving space in distribution boards and simplifying installation. The B characteristic ensures sensitive response to common overloads and short-circuits in lighting and socket circuits. The 30 mA residual-current sensitivity provides protection against hazardous AC earth-leakage currents while allowing normal appliance operation where DC components are not expected. The compact two-pole design is suitable for single-phase circuits and offers a straightforward mechanical switching operation for clear ON/OFF states.
Suitable for
 Protection of single-phase domestic lighting and socket circuits
 Small commercial or office electrical circuits with AC loads
 Distribution boards where combined RCBO functionality saves space
 Circuit protection in renovation projects where earth-leakage detection is required
Key specifications
 Poles: 2-pole device suitable for single-phase circuits
 Overcurrent characteristic: B-type tripping curve for general-purpose circuits
 Rated current: 20 A
 Residual-current sensitivity: 30 mA (0.03 A), Type AC (detects alternating-current leakage)
 Functions: Combined overcurrent (MCB) and residual-current (RCD) protection
 Operation: Manual toggle for ON/OFF with automatic trip on fault
How to use
Install the Eti-Polam KZS-2M in a distribution board on standard DIN rail according to local electrical codes. Connect the phase and neutral conductors to the respective incoming and outgoing terminals; ensure correct polarity and tighten terminal screws to the manufacturer’s recommended torque. Use the manual toggle to switch the circuit ON and OFF during commissioning and testing. Periodically test the residual-current function according to local regulations by using a test button on the device or following prescribed test procedures to confirm correct tripping behavior.
Usage recommendations
Fit this device as part of a complete protective system that includes proper earthing, appropriate upstream and downstream breakers, and wiring sized for 20 A. Do not use a Type AC residual-current device where pulsed DC or smooth DC leakage may occur; in such cases choose a device with suitable sensitivity class. Have installation and testing performed by a qualified electrician in accordance with applicable standards and local regulations.
