Fusebox Fused Switch 100A 100Ma Time Delayed Type A SF0100RA

FuseBox SF0100RA — 100A 100 mA Time-Delayed Type A Fused Switch (1P+N)

The FuseBox SF0100RA combines a robust 100 A fused isolator with a 100 mA time-delayed Type A residual current device (RCD) and interchangeable 63A, 80A and 100A gG fuses, all packaged in a compact steel enclosure. It's purpose-designed for incoming supply isolation and enhanced residual-current protection in domestic and light-commercial applications.

With its high current rating, time-delayed Type A response (which covers both AC and pulsating DC residual currents) and fuse holder flexibility, the SF0100RA offers installers a practical all-in-one solution for modern installations that demand reliability and future-proofing.

Installer-Focused Performance: This unit offers the key features contractors value: a steel enclosure with top and bottom knock-outs (Ø25mm + Ø32mm) for flexible cable entry, a tail-clamp capable of up to 25mm² conductors, a padlock facility for isolation security, and support for up to 35mm² fuse-holder tails. The enclosure dimensions (260 × 156 × 94mm), IP20 rating and clear manufacturer instructions streamline installation and auditing.

Suitable Applications: Ideal for incoming supply isolation at meter tails, consumer units with high demand circuits (EV charging, heat pumps, smart systems), and distribution boards where both fused isolation and residual-current protection are required in one space-efficient unit.

Key Features of the FuseBox SF0100RA Include:

• 100 A fused switch for high-capacity supply circuits
