Eaton 355A Tag Fuse 201 x 74 x 74 mm 1500V, 170 mm

This tag fuse is designed for use in photovoltaic systems to protect DC circuits up to 1500 V. It provides Rapid disconnection under fault conditions within solar arrays and is suitable for integration into PV combiner boxes and string-level protection assemblies. The product meets industry electrical safety expectations and fits installations requiring a compact, dedicated solar fuse solution.

• 355 A continuous current rating for high-load PV strings
• High-speed operation for fast fault interruption
• 100 kAIC rupture capacity for severe short-circuit events
• Conforms to IEC 60269 for standardised electrical behaviour

• Suitable for protection of solar string circuits in utility-scale farms
• Ideal for combiner boxes in rooftop PV installations
• Used with DC isolation assemblies in commercial arrays
• Can be used for modern 1500V solar inverter input protection

The fixing centres are 170mm which determines the panel cut-out and Terminal bracket spacing for secure attachment.

The overall envelope measures 201 x 74 x 74 mm, useful for calculating cut-outs and enclosure clearances.

The high-speed characteristic enables selective clearing ahead of downstream protective devices, reducing energy let-through during faults.
