## Summary description

The Bemko Schelinger A03-K7-4-40-030 is a 4-pole residual current circuit breaker (RCCB) designed for electrical safety. It features a 40A rated current and 30mA sensitivity, providing protection against leakage currents in AC circuits. This device is essential for preventing electric shocks and ensuring the safety of electrical installations in residential and commercial buildings.

## Long description

The Bemko Schelinger Residual Current Circuit Breaker (RCCB) is a high-quality electrical safety device engineered to protect circuits against leakage currents. Designed for 4-pole configurations, this unit operates effectively in AC systems, ensuring reliable performance in both residential and commercial electrical installations. By continuously monitoring the balance of current, it acts as a critical safeguard against electric shocks and potential fire hazards caused by insulation faults.
Advantages
This residual current circuit breaker offers robust protection by quickly disconnecting the power supply when a leakage current is detected, significantly reducing the risk of injury. Its durable construction ensures long-term reliability and consistent operation under standard electrical loads. The device is designed for easy integration into modern distribution boards, providing a seamless solution for enhancing the safety profile of any electrical network.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Protection of lighting and socket circuits
General electrical safety upgrades
This device is not suitable for DC-only circuits or systems requiring specific Type A or Type B protection against pulsating or smooth DC leakage currents. It should not be used as a substitute for a miniature circuit breaker (MCB) as it does not provide protection against overloads or short circuits.
Key specifications
Number of poles: 4
Rated current: 40A
Rated residual operating current: 30mA
Type: AC
Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is typically mounted on a standard DIN rail within a consumer unit. Ensure that the supply voltage matches the device ratings and that all connections are tightened to the specified torque to prevent overheating.
What to consider before purchase
Verify the total load of the circuit does not exceed 40A
Ensure the installation environment is compatible with AC type RCCBs
Check available space in the distribution board for a 4-pole device
Regularly test the device using the integrated test button to ensure the mechanical tripping mechanism remains functional and provides ongoing protection.
