## Long description

The Eti-Polam KZS-4M is a high-performance residual current circuit breaker with overcurrent protection (RCBO), engineered to provide integrated safety for electrical circuits. This 3P+N device combines the functions of a miniature circuit breaker and a residual current device into a single compact unit, offering protection against overloads, short circuits, and dangerous leakage currents. Designed for reliability, it serves as a critical component in modern electrical distribution systems, ensuring both equipment longevity and user safety.
Advantages
The primary benefit of the Eti-Polam KZS-4M is its space-saving design, which integrates two essential protective functions into one housing, simplifying installation and reducing the required space in distribution boards. The Type A sensitivity ensures reliable detection of both alternating and pulsating direct residual currents, providing a higher level of safety compared to standard AC types. Its robust construction and precise tripping characteristics make it a dependable choice for maintaining continuous operation while preventing electrical hazards.
Suitable for
Residential electrical distribution boards
Commercial and office building power systems
Industrial machinery and equipment protection
Protection of circuits with electronic components sensitive to pulsating DC
This device may not be suitable for applications requiring specific tripping curves other than C, or for systems where the rated current exceeds 16A. It is also not intended for use in environments with extreme temperatures or high levels of corrosive substances that fall outside the manufacturer's specified operating conditions.
Key specifications
