Product information

Description

The Bemko Residual Current Circuit Breaker (RCCB) is a high-quality 2-pole electrical safety device engineered for AC circuits. With a rated current of 40A and a sensitivity threshold of 300mA, this device serves as a critical component in modern electrical distribution systems. It is designed to monitor the balance of current in a circuit and automatically disconnect the power supply if a leakage current is detected, thereby preventing potential electrical hazards and protecting connected equipment.

Advantages

This residual current circuit breaker offers reliable performance and robust construction, making it an essential addition to any electrical panel. By providing rapid response times during fault conditions, it significantly enhances the safety profile of residential and commercial installations. Its compact design allows for efficient use of space within distribution boards, while the high-quality materials ensure long-term durability and consistent operation under standard environmental conditions.

Suitable for

  • Residential electrical installations
  • Commercial building power distribution
  • Protection of electrical circuits against leakage currents
  • General electrical safety upgrades

This device is not suitable for DC circuits or applications requiring high-speed protection against direct contact, as the 300mA sensitivity is primarily intended for fire protection and equipment safety rather than human life protection against direct touch. It should not be used in environments where the leakage current threshold needs to be significantly lower, such as in bathrooms or areas with high moisture levels where 30mA devices are typically required.

Key specifications

  • Type: Residual Current Circuit Breaker (RCCB)
  • Poles: 2P
  • Rated current: 40A
  • Sensitivity: 300mA
  • Current type: AC

The device should be installed by a qualified electrician in accordance with local electrical regulations. It is typically mounted on a standard DIN rail within a distribution board. Once installed, it is recommended to test the device periodically using the integrated test button to ensure the internal mechanism remains functional and capable of tripping when a fault occurs.

What to consider before purchase

  • Ensure the rated current of 40A matches your circuit requirements
  • Verify that the 300mA sensitivity is appropriate for your specific fire protection or equipment safety needs
  • Confirm compatibility with your existing electrical distribution board and DIN rail system

Usage recommendations

Regularly press the test button on the device at least every six months to verify that the tripping mechanism is operating correctly and to maintain optimal safety levels in your electrical installation.
