Eti-Polam KZS-2M2p EDI A Residual Current Circuit Breaker with Overcurrent Protection 1+N 16A C 30mA Type A

The Eti-Polam KZS-2M2p EDI A is a high-performance residual current circuit breaker with overcurrent protection, commonly known as an RCBO. This device integrates the functions of a miniature circuit breaker and a residual current device into a single compact unit, designed specifically for 1+N electrical systems. It provides comprehensive protection for electrical circuits by monitoring for both overcurrent conditions and leakage currents, thereby safeguarding both the electrical infrastructure and the users connected to it.

Advantages

The primary benefit of this device is its space-saving design, which combines two essential safety functions into one module, making it ideal for modern distribution boards where space is limited. The Type A sensitivity ensures reliable detection of both alternating and pulsating direct residual currents, offering a higher level of safety compared to standard AC-type devices. Its robust construction and C-type tripping characteristic make it highly effective at handling the inrush currents typical of inductive loads, ensuring that the circuit remains stable during normal operation while providing rapid disconnection in the event of a fault.

Suitable for

• Residential electrical installations
• Commercial office circuit protection
• Lighting and power outlet circuits
• Protection of sensitive electronic equipment

This device may not be suitable for industrial applications requiring high-amperage protection or for circuits with specific requirements for time-delayed tripping. It is also not intended for use in DC-only electrical systems or environments where the leakage current characteristics fall outside the scope of Type A protection.

Key specifications

• Rated current: 16A
• Tripping characteristic: C-type
• Residual current sensitivity: 30mA
• Device type: Type A
• Configuration: 1+N

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 cables are securely fastened to the terminals and that the wiring configuration matches the 1+N layout requirements. Once installed, the device should be tested using the integrated test button to verify its mechanical and electrical functionality.

What to consider before purchase

• Verify that the 16A rating matches your circuit load requirements
• Ensure the 30mA sensitivity is appropriate for the intended level of human protection
• Confirm that the DIN rail mounting space is available in your distribution panel
• Check that the Type A classification meets the specific safety standards required for your equipment

Regularly test the functionality of the RCBO using the integrated test button at least every six months to ensure the mechanism remains operational and provides continuous protection.
