Why Choose the Wöhner 31300 Class CC Fuse Holder with LED?
The Wöhner 31300 is a premium 3-pole Class CC fuse holder with integrated LED indication, designed to deliver dependable overcurrent protection while providing instant visual indication of a blown fuse. As part of the trusted Wöhner AMBUS® Panel range, it is ideal for industrial control panels, OEM machinery and low-voltage power distribution systems requiring reliable UL and CSA approved circuit protection.
Designed for installation on a standard DIN mounting rail, the Wöhner 31300 accepts Class CC fuse links manufactured to UL 248-4. The built-in LED illuminates when a fuse link has operated (while the closed fuse holder remains energised), allowing maintenance engineers to identify faults quickly and minimise production downtime. The indicator operates on 110–600 V AC/DC and supports either polarity on DC systems.
With a 30 A rated current, 600 V AC/DC operating voltage and a compact 3-pole configuration, the Wöhner 31300 is well suited to protecting three-phase machinery, industrial automation equipment, motor control centres and feeder circuits where reliable protection and rapid fault diagnosis are essential.
