Reliable Two Pole Protection – Type A 100A Time Delayed RCD
Fusebox RTA1001002S
The FuseBox RTA1001002S is a Type A 100A Time Delayed S Type RCD designed for enhanced protection and circuit selectivity. This two pole RCD (also known as a double pole residual current breaker) offers delayed disconnection to prevent unnecessary tripping in systems with multiple RCDs, ensuring only the faulted circuit is isolated.
🔍 Key Features – Time Delayed S Type RCD
- Rated current: 100A
- Sensitivity: 100mA (High Sensitivity Residual Current Device)
- Type A + Type S: Detects AC & pulsating DC leakage currents
- Time-delayed tripping to coordinate with downstream devices
- 2 Pole (L + N switching)
- DIN rail mounting
- IP20 rated, 230V, 50/60Hz
- Fully compliant with EN/IEC 61008-1
🛡️ What is a Type S RCD?
The “S” in RTA1001002S indicates selectivity—meaning this Type S RCD includes a built-in time delay. It won’t trip instantly on a fault, allowing faster RCDs downstream to act first. This is essential in installations where multiple RCDs exist in series, such as between a main incomer and final circuits. It’s ideal for submains or incoming circuits on larger boards.
✅ Why Choose This Delayed Trip RCD?
Choose the FuseBox 100A Time Delayed RCD when you need a dependable, selective, and standards-compliant solution for circuit protection. It’s a great option when you’re wiring between consumer units, protecting distribution boards, or dealing with complex multi-RCD setups.
🆚 Instantly Tripping Option – Non-Selective RCD for FuseBox Boards
If you’re not looking for time delay, try the FuseBox RTA1001002 – 2 Pole 100A 100mA Type A RCD. This fast-acting residual current device provides immediate disconnection and is ideal for general fault protection without selective tripping delays.
