40A Single Pole B Curve 10kA Type A RCBO For Residential And Light Commercial Distribution Boards

The 40A Single Pole B Curve 10kA Type A RCBO is a compact safety device that protects both people and circuits by combining residual-current protection with overcurrent protection. Designed for residential and light commercial distribution boards, it delivers reliable leakage and overload protection in a single, easy-to-install unit.

• Rated current: 40A
• Pole configuration: Single Pole (SP)
• Tripping curve: B Curve
• Breaking capacity: 10 kA
• RCD Type: Type A (detects AC and pulsating DC residual currents)
• Protection: Combined residual-current and overcurrent protection (RCBO)

This RCBO helps prevent electric shock by automatically disconnecting the circuit when leakage current is detected, and it also interrupts faults caused by overloads. The 40A rating makes it suitable for common circuits such as lighting and general power outlets in homes and small offices. The B curve provides a quick yet controlled response to short-circuit events under typical load conditions, while Type A sensing covers pulsating DC leakage from modern electronic devices. By combining RCD and MCB functionality in one unit, it simplifies installation, reduces wiring complexity, and enhances reliability within your distribution board.
