Description
Hager Residual Current Device 40A 4P 30mA Type AC
Residual current device 4P 40A 30mA Type AC CDC440J by HAGER is an electrical device designed to immediately disconnect the circuit when it detects imbalances in the flow of outgoing and incoming currents.
Model CDC440J is primarily used to provide protection against electric shock in case of direct or indirect contact. Additionally, it helps to reduce the risk of equipment damage and prevents fires caused by electrical faults.
Key features
- Stable and secure mounting on DIN rail using a solid metal bracket.
- Provides touch protection (IP2x) even when using busbar systems.
- Terminal cover preventing incorrect wire connection, minimising the risk of installation errors.
- Residual current indicator enabling quick identification of whether tripping occurred due to residual current or manual disconnection.
- True contact position indicator showing whether the device contacts are actually mechanically open.
- Safe live working thanks to the possibility of using insulated screwdrivers, preventing housing damage.
- Sealing capability in special applications, ensuring control over unauthorised access.
- The device protects cables, property and human life from dangerous effects of electric current.
- All devices meet the requirements of British Standards and conditions necessary for CE marking, which testifies to their quality and safety.
- Possibility to expand existing installations thanks to 100% compatibility with the previous series, facilitating system modernisation.
