Fusebox 100A 4 Pole Type A RCD 300mA RTA1003004

FuseBox RTA1003004 — 100A 300mA Type A 4-Pole RCD

The FuseBox RTA1003004 is a heavy-duty 100A 300mA Type A 4-pole RCD designed for commercial and industrial installations where higher residual-current thresholds and robust, system-level fault protection are required. Offering 4-pole isolation (L1, L2, L3, N), this RCD is ideal for TPN distribution boards and three-phase applications where equipment protection or fire-prevention RCD characteristics are needed.

With Type A detection, the RTA1003004 provides protection against AC and pulsating DC earth leakage — a key requirement for modern three-phase systems with electronic loads. The 300mA sensitivity makes it suitable for circuits not requiring personal protection but still needing reliable residual-current monitoring to reduce fire risk.

Built for Demanding Three-Phase Installations: The RTA1003004 forms part of the FuseBox TPN protection range and is designed for compatibility with FuseBox 3-phase distribution boards. It supports stable operation on high-load systems and helps prevent upstream tripping thanks to its higher residual rating.

Installer-Friendly Performance: Engineered for quick DIN-rail installation and consistent long-term performance, this RCD offers a dependable solution for contractors working on commercial builds, industrial plants, and mixed-load environments where durable protection is essential.

Key Features of the FuseBox RTA1003004 Include:

• 300mA Residual Current Sensitivity Suitable For Equipment And Fire Protection
• Type A Detection For AC And Pulsating DC Leakage Currents
• 4-Pole Isolation Covering L1, L2, L3 And Neutral For Full Three-Phase Protection
• Rated At 100A For High-Load Commercial And Industrial Installations
• Ideal For TPN Boards And Three-Phase Distribution Systems
• Reliable Performance For Mixed Electronic Loads And Modern Installations
• DIN-Rail Mounting For Fast, Contractor-Friendly Installation
• Designed And Tested To EN/IEC Standards For Safety And Compliance
