Residual current circuit breaker with overcurrent release 4P 6kA B 10A/30mA A QC/QB ADM410QC

RCBO Residual Current Breaker with Overcurrent Protection ADM410QC

The RCBO residual current breaker with overcurrent protection ADM410QC is a protective device that combines the functions of an overcurrent circuit breaker and a residual current device in a single unit. This provides multi-level protection against electric shock, overload, and short circuits.

Design and technical parameters of the device

The device is designed with a compact, modular construction with a width of 4 modules (71mm), allowing for easy mounting on a standard TH35 DIN rail. The IP20 protection class ensures safe installation inside electrical distribution boards.

Basic electrical parameters include a rated current of 10A at a rated voltage of 400V, allowing for effective protection of medium-power circuits. The rated residual current of 30mA with Type A sensitivity ensures high sensitivity in detecting earth leakage current, protecting against electric shock. A short-circuit breaking capacity of 6kA guarantees the safe interruption of even high short-circuit currents. The Type B tripping characteristic has been specifically selected for optimal protection of resistive-inductive circuits, where both resistive loads and motors are present.

The device operates in a temperature range from -25°C to +40°C. An insulation voltage of 500V and surge immunity up to 4kV ensure a high level of electrical safety.

Connection system and device mounting

The RCBO ADM410QC is equipped with an innovative connection system consisting of two technologies:

• Top QuickConnect connection - enables rapid installation of supply wires without the need for tools, significantly speeding up the installation process
• Bottom Biconnect connection - provides a secure connection for loads with the possibility of using single-core wires (1-25mm²) or multi-core wires (1-16mm²)

The terminal tightening torque is 2Nm, which guarantees optimal electrical contact while maintaining ease of installation. The possibility of 360° rotary mounting provides flexibility in distribution board planning.

Safety and technical standards

The device complies with the requirements of the EN/IEC 61009-1 standard, ensuring full compliance with European safety standards. An I²t energy limiting class of 3 limits the short-circuit energy to a safe level, protecting the installation from damage.

Protection against "false" unwanted tripping and the inability to simultaneously disconnect the N pole ensure stable operation of TN-S and TN-C-S systems. An operating frequency of 50Hz and AC supply voltage guarantee compatibility with power grids.

The CE Declaration of Conformity and available technical documentation confirm the highest quality standards of this device.
