• Ideal for protecting electrical installations in commercial sites
• Utilised in industrial settings to safeguard machinery and equipment
• Suitable for residential requiring enhanced safety
• Designed for seamless compatibility with MCBs in the S200 series

A 30mA sensitivity rating means it will trip when detecting leakage currents of 30mA or more, thereby minimising the risk of electric shock and ensuring user safety.

It conforms to IEC/EN 61009, which ensures it adheres to established safety and performance guidelines for residual current devices.

It requires a DIN rail mounting, which provides a secure and standardised installation method in electrical distribution boards.

The unit is designed to operate efficiently in temperatures ranging from -25°C to 55°C, making it suitable for various environments.

It offers earth leakage protection type A, protecting against the effects of earth faults and ensuring safety during electrical failures.
