Fusebox 100A 2 Pole Type A RCD S Type RTA1001002S

Fusebox RTA1001002S — 100A 100mA Type A-S Time-Delayed 2-Pole RCD

The Fusebox RTA1001002S is a 100A 100mA Type A-S (time-delayed) 2-pole RCD designed for selective protection where discrimination between upstream and downstream devices is required. Ideal for sub-distribution boards and circuits where nuisance tripping must be minimised, this device provides robust residual current protection while maintaining coordination with other RCDs in the system.

Built to EN/IEC61008-1 and offering a strong 10kA breaking capacity, the RTA1001002S is engineered for reliability in demanding installations. The time-delayed Type S response ensures the device trips within defined selectivity windows, enabling safer layered protection in multi-RCD configurations.

Selective, Installer-Friendly Protection: The Fusebox RTA1001002S features polarity-free terminals, allowing line and neutral to be wired to either side, and supports load connection from the top or bottom—ensuring maximum flexibility inside consumer units. Its generous 35mm² terminal capacity and 2.5Nm tightening torque specification provide a secure, trade-friendly installation.

Reliable Performance for Layered Systems: With a mechanical endurance of 10,000 cycles, consistent trip characteristics, and purpose-designed Type S time delay, this RCD supports safe, selective protection in both domestic and commercial environments where multiple RCDs operate in series.

Key Features of the Fusebox RTA1001002S Include:

• Selective Time-Delayed Protection For Layered RCD Systems
• Type A-S Response Suitable For AC And Pulsating DC Leakage
• High 10kA Breaking Capacity For Added Installation Safety
• Flexible Polarity-Free Wiring To Simplify Board Layout
• Load Connection Permitted At Top Or Bottom For Faster Setup
• Reliable 10000 Mechanical Endurance Cycles For Long-Term Durability
• Large Terminal Capacity Up To 35mm² For 100A Circuits
• Standard 35mm DIN Rail Mounting For Quick Installation
• Rated Residual Operating Current Of 100mA For Enhanced Fault Protection
• Weight: 0.23kg
