KOOP Elektro FSS Residual Current Circuit Breaker 4P 63A 30mA Type A

The KOOP Elektro FSS residual current circuit breaker is a high-performance 4-pole electrical protection device engineered to safeguard residential and industrial electrical systems. With a rated current of 63A and a sensitivity of 30mA, this Type A device is designed to detect and interrupt circuits in the presence of residual currents, including both alternating current and pulsating direct current. By integrating this component into your electrical distribution board, you significantly reduce the risk of electric shocks and prevent potential fire hazards caused by insulation faults.

Advantages

This residual current circuit breaker offers robust protection by reacting to a wider range of fault currents compared to standard AC-type devices. Its Type A classification ensures compatibility with modern electronic equipment that may generate pulsating DC components, such as power supplies, LED drivers, and variable speed drives. The modular design allows for seamless installation on standard DIN rails, making it a versatile choice for both new electrical projects and system upgrades. Its durable construction ensures long-term reliability and consistent performance in demanding electrical environments.

Suitable for

• Residential electrical distribution boards
• Industrial power supply systems
• Protection of circuits with electronic components
• Installations requiring Type A residual current protection

This device may not be suitable for systems requiring a higher sensitivity than 30mA or for applications where the total load current consistently exceeds the 63A rating. It is also not intended for use in DC-only circuits or environments with extreme environmental conditions that fall outside the manufacturer's specified operating temperature range.

Key specifications

• Number of poles: 4
• Rated current: 63A
• Residual current sensitivity: 30mA
• Type: A
• Mounting: DIN rail

To use the KOOP Elektro FSS residual current circuit breaker, it must be installed by a qualified electrician within a distribution board. The device is mounted onto a standard DIN rail and connected to the incoming and outgoing power lines according to the wiring diagram provided on the housing. Once installed, the integrated test button should be pressed periodically to verify the mechanical functionality of the tripping mechanism.

What to consider before purchase

• Verify that the 63A rating is sufficient for your total circuit load
• Ensure the 30mA sensitivity meets local safety regulations
• Confirm that your electrical system requires Type A protection
• Check available space in your distribution board for a 4-pole modular device

Usage recommendations: It is recommended to perform a functional test using the integrated test button at least every six months to ensure the device remains in optimal working condition. Always ensure that the electrical installation complies with local building codes and safety standards.
