Eaton 450A Tag Fuse 201 x 74 x 74 mm 1.5kV, 170 mm

This tag fuse provides overcurrent protection for photovoltaic installations and associated inverter systems operating up to 1500 V. It is designed for integration into PV array combiners and disconnect assemblies where Rapid interruption of fault currents is required. The component is intended for use in industrial and commercial solar power setups and complies with recognised international standards.

• 450A rating delivers high continuous current capacity
• High-speed operation minimises energy let-through during faults
• 100 kAIC high rupture capacity for substantial fault clearance
• Conforms to IEC 60269 for standardised performance assessment
• 170mm fixing centres enable straightforward panel mounting

• Suitable for inverter protection in utility-scale PV installations
• Ideal for photovoltaic array combiner boxes on commercial sites
• Used with solar disconnects for Rapid circuit isolation
• Can be used for protection of strings and subarray feeders

It interrupts large prospective currents up to 100 kAIC, limiting thermal and mechanical stress on downstream components.

The product is designed to be fixed using 170mm centre spacing to match common combiner and disconnect layouts.

Situations with Rapid fault energy accumulation—such as long DC runs in PV fields—benefit from its high-speed clearing characteristics.
