• Ensures protection against indirect contacts

• Compatible with MCBs from the S200 series

• Rated for both 230V and 400V AC applications

• Robust design to withstand ambient temperatures from -25 to 55°C

• Compact size optimises space in electrical installations

Applications


• Used for residential electrical installations and protection

• Ideal for commercial requiring reliable current protection

• Suitable for industrial setups needing robust electrical safety measures

• Fits into electrical panels alongside compatible MCBs

What is the specific role of the device in preventing electric shock?


The device detects faulty currents and disconnects the circuit immediately to prevent electric shock, safeguarding users from accidental electrocution during direct or indirect contact with live parts.

How does the installation process work for this type of circuit breaker?


The device utilises a DIN rail mounting style, allowing it to be easily clipped into place within a standard electrical panel, simplifying electrical installations without the need for special tools.

Can this RCD be used in conjunction with other circuit protection devices?


Yes, it is compatible with MCBs from the S200 series, enabling a comprehensive approach to circuit protection by combining multiple safety devices in the same panel.

What maintenance does this device require to ensure optimal performance?


Routine checks should be performed to ensure proper operation, including testing the trip mechanism using the built-in test button and ensuring that there is no physical damage to the unit or connections.

What are the implications of using a 30 mA sensitivity RCD compared to higher sensitivities?


A 30 mA sensitivity offers a balance of safety for human contact protection while minimising nuisance tripping in everyday use, making it suitable for most residential and commercial scenarios.
