NEOZED D0 Fuse-Links gG: 400V Protection for Panel Builders

In low-voltage power distribution networks where electrical cabinets are accessible to non-trained personnel, preserving operational safety while maintaining robust short-circuit defense is critical. Equipment failure or improper fuse replacement directly threatens facility uptime and operator safety.

Product Overview

The Mersen NEOZED D0 series is the most modern screw-type fuse system designed specifically for 400VAC / 250VDC network protection. Engineered with a gG operating class, these fuse-links efficiently sever unacceptable overcurrents and limit high short-circuit currents up to an interrupting rating of 50 kA. Available in standardized D01, D02, and D03 sizes, the NEOZED system provides inherent user safety through its screw-cap design, making replacements seamless and secure. The lineup also features specialized Marine-rated fuse-links rated up to 440VAC, built for offshore and harsh-environment panelboards.

Typical Applications

• House incoming units and residential service panels
• Commercial meter distribution units and sub-panels
• General cabling and power line protection
• Marine distribution cabinets (440VAC versions)
• Standard industrial installation cabinets and fuse boxes

Key Features & Benefits

• Enhanced Thermal Body: Insulated structure engineered to absorb high mechanical and thermal impacts.
• Premium Contacts: Top and bottom contacts crafted from nickel-plated or silver-plated copper alloy for minimal power dissipation.
• Visual Indication: Color-coded operation indicators on the top contact allow instant identification of blown fuses.
