Eaton xEffect Series Fuse Holder, 250A Current, 800V Voltage - 183056 XNH1-FCE-S250-BT


This fuse holder is a three-pole NH1 device designed for integration into busbar-mounted electrical panels, providing electronic fuse monitoring and a front-mounted actuator for manual operation. It is intended for industrial control and distribution systems where secure box-terminal connections and fault indication are required.

Features & Benefits


• 250A rated current for high-current distribution capability
• 800V rated insulation for robust voltage endurance
• Electronic fuse monitoring with LEDs and test button for quick diagnostics
• Frame-clamp main circuit connection for reliable conductor retention
• IP10/IP20/IP2XC/IP3X protection offering varied contact safety levels
• Operates across -25°C to 70°C for broad environmental tolerance

Applications


• Suitable for busbar-mounted power distribution in factories
• Used for protecting motor control centres in automation systems
• Ideal for retrofit or replacement in low-voltage switchgear panels
• Can be used for feeder protection in electrical distribution boards

What cable sizes can be terminated at the box terminal?


Copper conductors from 35mm² up to 150mm² are supported at the box terminal, with specific clamp options accommodating dual or multiple conductor arrangements.

How is short-circuit performance characterised for panel design?


The device has a conditioned rated short-circuit current of 120kA and a short-time withstand rating of 6kA to inform switchgear fault-level calculations.

Which mounting and orientation options are available?


It is designed for 60mm busbar mounting and may be installed vertically or horisontally to suit panel layouts.

What indicators and outputs does the monitoring provide?


The electronic monitoring includes three red fault LEDs, one green status LED, one NC and one NO relay contact, and a manual test button for relay verification.

How does the device address electromagnetic compatibility testing?


The electronic monitoring complies with surge and fast-transient immunity as per relevant EMC test standards, supporting stable operation in industrial environments.
