DIN Rail Fuse Holder NH00 160A Knife Switch Fuse Base

The ZHENGRONG NH00 fuse switch disconnector is a professional-grade fuse holder designed for low-voltage electrical circuits requiring both overcurrent protection and visible isolation. Built to the standard NH00 fuse-link size, it accepts widely available NH00 gG/aM fuse links up to 160A, making it a versatile and economical choice for panel builders, contractors and maintenance engineers.

The holder integrates a knife-switch mechanism: when the fuse link is removed or the switch is opened, a clear visible break is formed, guaranteeing safe isolation during maintenance. The housing is molded from high-strength, flame-retardant engineering plastic with a translucent blue cover window, so the fuse condition can be inspected at a glance without opening the unit — reducing downtime when a fuse operates.

Installation is tool-free: the base snaps directly onto standard 35mm DIN rails, and the compact NH00 footprint saves space inside control cabinets and distribution boards. All conductive parts use high-conductivity copper or brass with anti-oxidation plating to keep contact resistance and temperature rise low.

Feature

Visible isolation & safe maintenance — knife-switch design provides a clear visible break when the fuse is removed, ensuring operator safety during inspection and replacement.

Tool-free DIN rail mounting — snaps directly onto standard 35mm rails, speeding up installation and reducing labor cost.

Instant fuse status check — translucent blue window allows blown-fuse detection at a glance without opening the cover, minimizing downtime.

Flame-retardant housing — high-strength engineering plastic with excellent impact resistance, corrosion resistance and aging resistance for long service life.

Low temperature rise — high-conductivity copper/brass terminals with anti-oxidation plating keep contact resistance low and performance stable.

Standard NH00 fuse size — compatible with widely available NH00 gG/aM fuse links up to 160A for easy sourcing and replacement.

Space-saving design — compact NH00 footprint fits dense cabinet layouts and supports multi-pole combinations.

Quality certified — manufactured under ISO9000 quality management, with CCC (China) and CE (EU) compliance.
