The 811 Series Class CC and Midget-Style (10×38 mm) fuse holders replace traditional screw-based terminations with CAGE CLAMP® Spring Pressure. Beyond maintenance-free, vibration-proof connections, these lift-and-lock terminations reduce wiring times up to 50% — no torque specs or specialty tools.
Accommodating conductors 14–6 AWG, the fuse holders are available in 1–3 poles; an optional coupling kit creates multi-pole configurations in the field. The Class CC Fuse Holder supports branch-circuit applications with up to 200 kA SCCR (30 A, 600 V). The Midget-style variant achieves 100 kA SCCR (30 A, 750 Vac/1,000 Vdc) for supplemental protection — the 1,000 Vdc, 1-pole model suits PV combiner boxes. The holders have a DIN-rail mount clip for easy install or removal.
