Fusebox 100A 4 Pole Type A RCD 100mA RTA1001004

FuseBox RTA1001004 — 100A 100mA Type A 4-Pole RCD

The FuseBox RTA1001004 is a 100A 100mA Type A 4-pole RCD engineered for dependable residual-current protection in commercial, industrial and three-phase installations. Designed to isolate L1, L2, L3 and Neutral simultaneously, it delivers robust system protection where 100mA sensitivity is required for fire protection, equipment safeguarding, or upstream selectivity.

Type A technology ensures reliable detection of AC and pulsating DC leakage currents, making the RTA1001004 suitable for modern installations containing electronic equipment, variable-speed drives and mixed-load environments. Its higher residual rating provides essential protection without the nuisance tripping associated with more sensitive devices.

Reliable Three-Phase Protection: Built for FuseBox TPN distribution boards, the RTA1001004 offers stable and consistent performance across demanding three-phase circuits. The 100A rating supports high-load applications, while 4-pole switching improves system safety during fault conditions and scheduled maintenance.

Installer-Friendly Design: Compatible with standard 35mm DIN-rail systems, the RCD allows fast, precise installation. Its specification meets EN/IEC standards, giving contractors confidence in compliance across commercial and industrial projects.

Key Features of the FuseBox RTA1001004 Include:

• 100mA Residual Current Sensitivity For Fire And Equipment Protection
• Type A Detection For AC And Pulsating DC Leakage Currents
• 4-Pole Isolation Covering L1, L2, L3 And Neutral For Full Three-Phase Safety
