Description
WCED ATDR4100-300 4 Pole 100A A Type Time Delay RCD
WCED 4 Pole 100A A Type Time Delay RCD 300mA Trip
The WCED ATDR4100-300 is a robust 4-pole, 100A Type A Time Delay RCD with 300mA trip sensitivity. Unlike 30mA devices designed for personal protection, this 300mA RCD is intended for fire protection and system-level discrimination in distribution networks.
Its time delay function ensures that in multi-RCD installations, only the correct upstream device trips, preventing nuisance disconnections. With 6kA short-circuit rating, IP20 ingress protection, and proven endurance, this unit is engineered for safe, reliable operation.
