Why Choose the Mersen P204943 Open-Type Miniature Fuse Holder?
The Mersen P204943, catalogue reference MISIPTF15, is a compact open-type printed circuit board fuse holder designed for standard 5 x 20 mm miniature fuse links. It provides a straightforward and reliable method of incorporating replaceable overcurrent protection into electronic equipment, control assemblies and OEM electrical products.
Part of the Mersen IEC miniature fuse base range, the P204943 features a simple open construction that provides easy access to the installed fuse. Its PCB-mounted format supports space-efficient integration into electronic assemblies, while the flame-resistant insulating body helps provide dependable performance in professionally enclosed equipment.
With a rated current of 6.3 A and a rated operational voltage of 250 V AC, this single-pole fuse holder is suitable for low-voltage circuits operating at 50 or 60 Hz. The P204943 should be installed inside suitable equipment or an enclosure because its open design carries an IP00 protection rating.
