Eaton xEffect Series Fuse Holder, 250A Current, 800V Voltage - 183054 XNH1-FCL-S250-BT


This fuseholder is a three-pole device designed for installation on 60mm busbar systems to accommodate NH1 fuse-links in industrial electrical assemblies. It provides front-side actuation with a cover grip and offers Visual indication when a fuse has operated, making it suitable for panel and distribution environments where busbar-mounted fuse switching is required.

Features & Benefits


• 250A rated uninterrupted current for high-current circuits
• 800V insulation rating for elevated voltage systems
• 120 kA conditioned short-circuit capability for fault tolerance
• Sliding inspection windows allow safe voltage testing
• Box terminals accept 35mm² to 150mm² conductors for large cables
• IP20 protection in installed, operating condition for contact safety

Applications


• Suitable for low-voltage distribution on busbar-mounted switchgear
• Ideal for industrial control panels requiring Visual fuse status
• used with NH1 fuse-links in motor supply circuits
• Can be used for service isolation in factory distribution boards

What connection options are available for large conductors?


The device uses box-type terminals and clamp options that accept stranded cable from 10mm² up to 150mm² and copper strip arrangements, with flange connections allowing up to 37mm lug width and M10 bolts.

How does it cope with ambient temperature extremes?


It is rated to operate between -25 °C and 55 °C with a maximum component operating temperature of 70 °C and a heat deflection temperature of 125 °C.

What mechanical mounting orientations are permitted?


It can be mounted vertically or horisontally onto a 60mm busbar and supports front-side actuation for accessibility.

What materials and safety features reduce risk during maintenance?


The enclosure is MADE from polyamide with a halogen-free formulation, silver-plated electrolytic copper current paths, and optional locking for secure isolation.

What electrical endurance can be expected for switching operations?


Mechanical endurance is specified at 1,400 operations while electrical endurance is rated at 200 operations.
