ETI KZS-2M Residual Current Circuit Breaker with Overcurrent Protection, 16A, 30mA, Type AC

The ETI KZS-2M is a professional-grade residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive electrical safety in a single, space-saving unit. By integrating the functions of a miniature circuit breaker and a residual current device, this 2-module component effectively monitors electrical circuits to prevent hazards associated with short circuits, overloads, and dangerous leakage currents.

Advantages

This device offers a significant advantage in panel space management by combining two critical protective functions into one compact housing. Its robust construction ensures reliable performance in both residential and commercial electrical installations. The high sensitivity of the unit allows for rapid detection of faults, thereby minimizing the risk of electrical shock and fire damage. Furthermore, the design facilitates straightforward installation and maintenance, making it a dependable choice for modern electrical distribution systems.

Suitable for

• Residential electrical distribution boards
• Commercial office wiring systems
• Protection of individual lighting and socket circuits
• Preventing electrical shock in damp or high-risk areas

This device may not be suitable for industrial applications requiring high-amperage protection or specialized DC-sensitive leakage detection. It is designed specifically for standard AC electrical systems and should not be used in environments where the electrical load consistently exceeds the rated 16A capacity.

Key specifications

• Rated current: 16A
• Residual current sensitivity: 30mA
• Type: AC
• Module width: 2 modules
• Function: Combined overcurrent and leakage protection

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a distribution board. Ensure that the supply voltage matches the device specifications before connection. Once installed, the integrated test button should be used periodically to verify the functional integrity of the leakage protection mechanism.

What to consider before purchase

• Verify that the 16A rating is appropriate for your specific circuit load
• Ensure there is sufficient space on the DIN rail for a 2-module device
• Confirm that the AC type is compatible with your local electrical network requirements

For optimal safety and longevity, it is recommended to perform a functional test of the device using the integrated test button at least every six months to ensure the tripping mechanism remains responsive.
