Product information

Description

The Eti-Polam KZS-4M is a high-performance 4-pole residual current circuit breaker with overcurrent protection (RCBO), engineered to provide robust electrical safety in both residential and industrial environments. This device integrates the functions of a miniature circuit breaker and a residual current device into a single compact unit, ensuring efficient protection against short circuits, overloads, and dangerous earth leakage currents. By monitoring the electrical circuit continuously, it helps prevent equipment damage and enhances personal safety by disconnecting power in the event of a fault.

Advantages

This RCBO offers a space-saving design by combining two essential protective functions into one housing, which simplifies installation and reduces the amount of space required in electrical distribution boards. The B-type tripping characteristic ensures reliable performance for standard resistive and inductive loads, while the 30mA sensitivity is specifically calibrated to provide effective protection against indirect contact, significantly reducing the risk of electric shock. Its durable construction and high-quality components ensure long-term operational reliability and consistent performance under various load conditions.

Suitable for

  • Residential electrical distribution boards
  • Industrial power supply systems
  • Protection of lighting and heating circuits
  • General purpose electrical installations requiring earth leakage and overcurrent protection

This device is not suitable for DC-sensitive applications, as it is designed specifically for AC-type leakage currents. It should not be used in environments where high-frequency components or pulsating DC currents are present, as these may interfere with the tripping mechanism and lead to improper operation.

Key specifications

  • Number of poles: 4
  • Rated current: 25A
  • Tripping characteristic: B
  • Residual current sensitivity: 0.03A (30mA)
  • Device type: AC

The device should be installed by a qualified electrician in accordance with local electrical regulations. It is mounted onto a standard DIN rail within a distribution enclosure. Before installation, ensure that the power supply is disconnected and that the device ratings match the requirements of the circuit being protected. Once mounted, connect the supply and load conductors to the appropriate terminals, ensuring all connections are tightened to the specified torque to prevent overheating.

What to consider before purchase

  • Verify that the 25A rated current matches your circuit load requirements
  • Ensure the 4-pole configuration is compatible with your three-phase electrical system
  • Confirm that the AC type is appropriate for your specific application
  • Check the available space in your distribution board for a 4-module wide device
Regular testing of the device using the integrated test button is recommended at least every six months to ensure the mechanical tripping mechanism remains functional and provides ongoing protection.
