Wylex PSBS40-B/1 NH Series 1 Module SP+N B Curve Type A RCBO 40A 10kA 30mA
PSBS40-B/1
Wylex NH Series Single Pole + Neutral Type A RCBO – 40A Protection with 30mA Earth Fault Detection
The Wylex NH Series Type A RCBO combines MCB overcurrent protection with RCD earth fault detection in a single compact unit. With a 40A rating, 10kA breaking capacity, and 30mA sensitivity, this RCBO is ideal for safeguarding final circuits in NH Type A & B distribution boards, ensuring compliance with modern electrical safety standards.
- Type A RCBO Protection – Detects AC and pulsating DC residual currents for enhanced electrical safety.
- Type B Tripping Curve – Trips between 3 to 5 times the full load current, making it suitable for residential and light commercial circuits.
- 40A Rated Current – Provides precise protection for lighting and low-power electrical circuits.
- 10kA Short-Circuit Capacity – Ensures high-level fault protection for demanding installations.
- 30mA RCD Sensitivity – Quickly detects and isolates earth faults to prevent electric shock.
- Single Pole + Neutral Configuration – Ensures reliable disconnection and protection of circuits.
- Compatible with NH Distribution Boards – Designed for seamless installation in Wylex NH Type A & B distribution boards.
