## Summary description

The Eti-Polam KZS-4M is a 4-pole residual current circuit breaker with overcurrent protection (RCBO). It features a 32A rated current, B-type tripping characteristic, and 30mA sensitivity for AC type leakage currents. Designed for electrical safety, this device combines short-circuit and overload protection with residual current monitoring in a single compact unit, ideal for residential and commercial distribution boards.

## Long description

The Eti-Polam KZS-4M is a high-performance 4-pole residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive electrical safety in a single, space-saving unit. This device integrates both short-circuit and overload protection with residual current monitoring, ensuring reliable operation in modern electrical distribution systems. With a rated current of 32A and a B-type tripping characteristic, it is specifically designed to handle standard residential and commercial loads while maintaining high sensitivity to AC-type leakage currents.
Advantages
The primary advantage of the Eti-Polam KZS-4M is its compact design, which combines two essential safety functions into one device, significantly reducing the space required in distribution boards. By integrating overcurrent and residual current protection, it simplifies installation and maintenance while ensuring rapid response times during electrical faults. The robust construction and precise B-curve tripping characteristic offer excellent protection against both minor overloads and dangerous short circuits, providing peace of mind for both residential and commercial electrical installations.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Protection of lighting and general-purpose circuits
Electrical installations requiring combined overload and leakage protection
When it may not be suitable
This device is designed for AC-type leakage currents and may not be suitable for circuits containing electronic equipment that generates DC components, such as certain types of variable speed drives or advanced power electronics. In such cases, a Type A or Type B RCBO would be required to ensure proper detection of residual currents.
Key specifications
Number of poles: 4
Rated current: 32A
Tripping characteristic: B-curve
Residual current sensitivity: 30mA
Leakage current type: AC
How to use
The Eti-Polam KZS-4M should be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting on a standard DIN rail within a distribution board. Ensure that all supply and load cables are securely connected to the appropriate terminals, observing the correct torque settings. Once installed, the device can be manually switched on or off using the front lever, and the integrated test button should be used periodically to verify the functionality of the residual current protection mechanism.
What to consider before purchase
Verify that the 32A rated current matches the requirements of your circuit load.
Ensure the B-curve tripping characteristic is appropriate for your specific application.
Confirm that the installation environment does not require Type A or Type B protection for DC-sensitive equipment.
Check the available space in your distribution board for a 4-pole device.
Usage recommendations
Regularly test the residual current protection by pressing the test button at least every six months to ensure the device remains in optimal working condition. If the device trips frequently, investigate the circuit for potential faults or overloads before resetting.
