OP520 5x20mm Panel Mount Fuse Holder 10A 250VAC/125VDC
The OP520 is a 5x20mm panel mount fuse holder designed for front-panel installation. It accepts standard 5x20mm cylindrical fuses and is rated 10A at 250VAC or 125VDC.
This fuse holder uses PBT (polybutylene terephthalate) base material rated UL 94 V0 for reliable flame retardant performance. It features phosphor copper terminals of 0.5mm thickness for stable electrical contact. Besides, it withstands 3000VAC dielectric voltage and maintains insulation resistance above 100MΩ.
The OP520 has an interrupt capacity of 50A and contact resistance below 5mΩ. It is designed for panel mounting with a Ø11mm mounting hole and Ø14.7mm front bezel.
