It features a 25A rated current, C-type tripping characteristic, and 0.03A 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 unit, ensuring reliable circuit protection in residential and commercial installations.

## 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 compact unit. This device integrates both short-circuit and overload protection with residual current monitoring, making it an essential component for modern electrical distribution systems. By combining these functions, it effectively protects circuits against dangerous leakage currents and electrical faults, ensuring reliable operation in both residential and commercial environments.
Advantages
This RCBO offers significant space-saving benefits by consolidating multiple protective functions into one device, which simplifies installation within distribution boards. The C-type tripping characteristic ensures robust performance for standard electrical loads, while the 0.03A sensitivity provides high-level protection against accidental contact with live parts. Its durable construction and reliable mechanical design contribute to long-term operational stability, reducing the need for frequent maintenance and enhancing overall system safety.
Suitable for
Residential electrical installations
Commercial building distribution boards
Protection of lighting and power circuits
General purpose electrical safety applications
This device may not be suitable for specialized industrial applications requiring high-frequency filtering or DC component detection, as it is specifically designed for AC type leakage currents. It should not be used in environments where the load characteristics exceed the rated 25A current or where specific tripping curves other than the C-type are required for motor starting or high-inrush current equipment.
Key specifications
Number of poles: 4
Rated current: 25A
Tripping characteristic: C
Residual current sensitivity: 0.03A
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 securely fastened to the terminals and that the wiring matches the circuit diagram provided on the device housing. After installation, it is recommended to perform a functional test using the integrated test button to verify the tripping mechanism.
What to consider before purchase
Verify that the 25A rated current matches your circuit requirements
Ensure the 4-pole configuration is compatible with your electrical system
Confirm that the AC type protection meets your local safety standards
Check the available space in your distribution board for a 4-module wide device
Usage recommendations: Regularly test the device using the integrated test button every six months to ensure the mechanical tripping mechanism remains functional and responsive.
