Eaton xEffect Series Fuse Holder, 630A Current, 800V Voltage - 183080 XNH3-FCL-S630-BT


This fuse holder is a three‑pole NH3 device designed for busbar systems to provide safe fuse switching and Visual fuse status indication in industrial switchgear. It is suited to front access installations and accommodates box‑terminal connections with light signalling for tripped fuse‑links, enabling Rapid identification and operation in electrical distribution panels.

Features & Benefits


• Rated for 630A continuous current supporting high‑current systems
• Insulation rating 800V providing high voltage withstand capability
• Conditioned short‑circuit rating 120 kA for robust fault performance
• Sliding inspection windows allow safe voltage testing during maintenance
• IP2XC IP20 IP10 protection levels offering contact and operational safety
• Halogen‑free polyamide construction for reduced combustibility risk

Applications


• Suitable for busbar‑mounted distribution modules in factories
• Ideal for low‑voltage switchgear in automation panels
• Used with NH3 fuse‑links in power distribution boards
• Can be used for front‑accessible service panels in utilities
• Suitable for retrofitting into existing switchgear with 60mm busbars

What cable sizes can be terminated at the box terminal?


The box Terminal accepts single conductors from 95mm² up to 300mm² and copper band connections such as 21mm x 1mm strips in multiple runs.

How is the device mounted to busbars?


It is designed for mounting on 60mm copper busbars and interfaces via frame clamps and flange connections using M10 bolts.

What operating temperature range is supported?


The device operates between −25 °C and 55 °C with a maximum component temperature rating of 70 °C during duty.

How does the unit indicate a blown fuse?


Optical signalling provides a Visual indication of triggered fuse‑links to speed fault identification.

What mechanical durability can be expected for routine operations?


Mechanical endurance is specified at 800 operations with electrical operations rated to 200 cycles.
