4 Pole 100A 100mA Time Delay Type A RCD
WCED ATDR4100-100
The WCED ATDR4100-100 is a 4-pole Time Delay RCD with a 100A rated current and 100mA earth-leakage sensitivity. Designed for use in systems with two RCDs installed in series, its time-delayed functionality enables effective discrimination, ensuring only the upstream RCD trips during a fault. This feature makes it an essential safety component for residential, commercial, and industrial setups.
Detailed Features and Functionality
This WCED Time Delay RCD provides advanced protection by detecting residual currents and ensuring selective tripping in multi-device installations. Moreover, its Type A classification enables it to handle AC and pulsating DC currents effectively, making it suitable for modern electrical systems.
The device operates at a rated voltage of 230/400V and supports a rated conditional short-circuit current of 10kA, offering robust protection in high-demand environments. Additionally, its mechanical durability of 4,000 cycles and electrical durability of 2,000 cycles ensure long-lasting performance.
The RCD complies with BS EN 61008-1, meeting rigorous safety and performance standards. Furthermore, its IP20 rating provides basic protection against dust and contact, making it suitable for indoor installations. It operates reliably within an ambient temperature range of -25°C to +40°C, ensuring consistent performance in various conditions.
