## Summary description

The Eti-Polam KZS-4M is a 4-pole residual current circuit breaker with overcurrent protection (RCBO). It features a 16A rated current, C-type tripping characteristic, and 30mA sensitivity for AC type leakage currents. Designed for electrical distribution systems, this device provides combined short-circuit, overload, and residual current protection in a single compact unit, ensuring enhanced safety for residential and commercial electrical installations.

## Long description

The Eti-Polam KZS-4M is a high-performance 4-pole residual current circuit breaker with overcurrent protection, commonly known as an RCBO. This device is engineered to provide comprehensive electrical safety by combining the functions of a miniature circuit breaker and a residual current device into one compact housing. It is designed to protect electrical circuits against both overcurrent conditions, such as short circuits and overloads, and leakage currents, ensuring reliable operation in various electrical distribution systems.
Advantages
The primary advantage of the Eti-Polam KZS-4M is its space-saving design, which integrates multiple protection functions into a single unit, simplifying installation and reducing the amount of space required in distribution boards. By offering both overcurrent and residual current protection, it significantly enhances safety by preventing damage to wiring and equipment while protecting users from the risks associated with electrical faults. Its robust construction and precise tripping characteristics ensure consistent performance and long-term reliability in residential and commercial environments.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Protection of lighting and power circuits
General electrical installations requiring combined safety features
This device is not suitable for applications involving DC-pulsating leakage currents, as it is specifically designed for AC type leakage. It should not be used in industrial environments where high-frequency interference or specific harmonic distortions might cause nuisance tripping, nor is it intended for circuits exceeding its 16A rated current capacity.
Key specifications
Number of poles: 4
Rated current: 16A
Tripping characteristic: C-curve
Residual current sensitivity: 30mA
Leakage current type: AC
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted on a standard DIN rail within a distribution enclosure. Ensure that the supply cables are correctly connected to the input terminals and that the load is connected to the output terminals, verifying that all connections are tightened to the specified torque to prevent overheating.
What to consider before purchase
Verify that the 16A rated current matches the requirements of your circuit
Ensure the 30mA sensitivity is appropriate for the intended level of protection
Confirm that the 4-pole configuration is compatible with your electrical system layout
Check that the C-curve tripping characteristic is suitable for the connected loads
For optimal safety and performance, it is recommended to perform a functional test of the residual current protection mechanism using the integrated test button at regular intervals, typically every six months, to ensure the device remains in good working order.
