Eaton xEffect Series Fuse Holder, 630A Current, 800V Voltage - 183082 XNH3-FCE-S630-BT


This fuse holder is a three-pole device designed to integrate with busbar systems and provide enclosed NH3 fuse accommodation for industrial switchgear. It offers electronic monitoring of fuse-links, front-side actuation via a cover grip and box Terminal connections for high-current distribution in automation and electrical installations.

Features & Benefits


• 630A rated current supports high-load circuits
• 800V insulation withstands elevated system voltages
• Electronic fuse monitoring enables remote fault indication
• 120kA conditional short-circuit rating tolerates severe faults
• Frame-clamp main connection simplifies secure current paths
• IP20 front protection allows safe operation access

Applications


• Suitable for busbar-mounted distribution in switchboards
• Ideal for controlling large motor feeders in factories
• Used with NH3 fuse-links for mains protection schemes
• Can be used for power distribution in automation panels
• Suitable for retrofitting into industrial control gear assemblies

What Terminal types and conductor sizes can it accept?


It provides box Terminal and clamp-type connections accommodating stranded cables from 95mm² up to 300mm² and copper busbar lugs up to 56mm width with M10 flange bolts.

How does the device indicate fuse status and faults?


The unit includes self‑supplied electronic monitoring with a relay, one green LED, three red LEDs for individual pole indication and a test button for relay verification.

What environmental and mounting constraints apply?


It is halogen‑free, suitable for vertical or horisontal mounting on 60mm busbars, and operates within an ambient range of -25°C to 55°C with maximum operating temperature rated at 70°C.

Which electrical endurance and mechanical life figures apply?


Electrical endurance is specified as 200 operations while mechanical lifespan is 800 operations for switching actions.

What safety and insulation parameters are relevant for panel designers?


Rated insulation voltage is 800V AC with an impulse withstand of 8kV and overvoltage category II/III depending on system voltage

creepage resistance is CTI600.
