£46.88
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.
The Wöhner 31300 combines dependable Class CC fuse protection with integrated LED indication, enabling engineers to identify operated fuse links quickly without unnecessary troubleshooting. This reduces maintenance time and helps maximise equipment availability in demanding industrial environments.
Its compact three-pole design is particularly suitable for protecting three-phase industrial machinery, automation equipment and electrical distribution systems. Large cage clamp terminals provide secure connections for a wide range of copper conductors while simplifying installation and servicing.
