## Long description

The Eti-Polam KZS-4M is a high-quality 4-pole residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive electrical safety in a single compact device. By integrating both short-circuit and overload protection with residual current monitoring, this unit effectively safeguards electrical circuits and connected equipment from potential faults. It is designed for reliable performance in both residential and commercial electrical systems, ensuring consistent protection against leakage currents and overcurrent conditions.
Advantages
The primary benefit of the Eti-Polam KZS-4M is its space-saving design, which combines two essential safety functions into one modular unit, simplifying installation and reducing the space required in distribution boards. The device offers high operational reliability and precise tripping characteristics, ensuring that power is interrupted only when necessary to prevent damage or hazards. Its robust construction ensures long-term durability, while the clear indication of fault status allows for quick identification and maintenance of electrical circuits.
Suitable for
Residential electrical installations
Commercial building power distribution
Protection of lighting and socket circuits
General electrical safety in industrial environments
This device may not be suitable for applications requiring DC-sensitive leakage protection, as it is specifically designed for AC type leakage currents. It is also not intended for use in environments with extreme environmental conditions that exceed the manufacturer's specified operating temperature or humidity ranges.
Key specifications
Number of poles: 4
Rated current: 10A
Tripping characteristic: C-type
Residual current sensitivity: 0.03A
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 board. Ensure that the supply cables are securely connected to the appropriate terminals and that the circuit load does not exceed the rated current of the breaker. Regular testing using the integrated test button is recommended to verify the functionality of the residual current mechanism.
What to consider before purchase
Verify the total load of the circuit to ensure the 10A rating is sufficient.
Confirm that the 4-pole configuration matches your electrical system requirements.
Ensure the C-type tripping characteristic is appropriate for the connected loads, such as motors or lighting.
Check the available space in your distribution board for a 4-module wide device.
Regularly test the residual current protection function by pressing the test button at least once every six months to ensure the device remains in optimal working condition.
