British General Fortress CUR100100TDA-01 Type A Double Pole 100mA Time-Delayed RCD – 100A Rated
Product Overview
The British General Fortress CUR100100TDA-01 Type A Double Pole 100mA Time-Delayed RCD is designed to deliver dependable earth leakage protection with a built-in time delay to prevent nuisance tripping in selectivity (discrimination) applications. Ideal for use in BG Fortress consumer units, this RCD is suitable for residential, commercial, and light industrial installations.
Key Features
- Time-Delayed (S-Type) – Allows discrimination with downstream RCDs to prevent unnecessary power loss.
- Type A – Detects both AC and pulsating DC residual currents.
- Double Pole – Simultaneously isolates live and neutral conductors.
- Positive Contact Status Indication – Clearly shows ON or OFF position.
- Manual Test Button – Enables routine safety checks.
- Lockable Device Option – Can be locked in the ON or OFF position using a device lock.
- High Safety Standards – 100mA earth leakage sensitivity and 6kA breaking capacity.
