PTF35 5x20mm Panel Mount Fuse Holder 10A 250VAC

PTF35 5x20mm Panel Mount Fuse Holder 10A 250VAC

The PTF35 is a 5x20mm panel mount fuse holder designed for front-panel installation with a wide panel thickness range. It accepts standard 5x20mm cylindrical fuses and is rated 10A at 250VAC.

This fuse holder uses PBT housing material rated UL 94 V0 for reliable flame retardant performance. It features a PC2 shocksafe protection category and IP40 degree of protection. Besides, its contact resistance stays below 5mΩ to ensure stable, low-loss electrical connection.

The PTF35 operates reliably across a wide ambient temperature range from -30°C to +85°C. It fits panel thickness from 0.8mm minimum to 6.5mm maximum, making it suitable for both thin metal panels and thick plastic enclosures. Its standard colour is black, and other colours are available on request.
