## Summary description

ETI fuse insert NH2/WT-2C (MPN 004139395) is a gF-type fast-acting NH fuse element rated 100 A and 500 V. Designed for installation in NH fuse bases and switchgear, it provides overcurrent protection for circuits in industrial and commercial electrical systems. Suitable for protecting transformers, motors, and distribution lines where fast interruption of fault currents is required.

## Long description

ETI fuse insert NH2/WT-2C gF 100A 500V fast is a gF-type fast-acting NH fuse element intended for use in NH fuse bases and switchgear. It is rated for 100 A continuous current and 500 V nominal voltage, providing overcurrent protection that interrupts fault currents rapidly. The design suits industrial and commercial electrical installations where selective and fast disconnection is required to protect equipment and maintain system safety.
Advantages
The fuse element offers fast-acting interruption characteristics in a standardized NH2 form factor compatible with NH fuse holders and switchgear. Its gF characteristic ensures both short-circuit and some controllable overload protection for semiconductor-fed circuits and motors. The compact construction facilitates straightforward replacement and limits downtime during maintenance. The product is designed to meet typical electrical safety and coordination requirements for mid-range distribution protection.
Suitable for
Protection of distribution lines in commercial and industrial switchboards
Short-circuit and selective protection of motors and motor starters
Protection of transformers and secondary circuits
Use in NH fuse bases and low-voltage distribution switchgear requiring gF fast fuses
Key specifications
Rated current: 100 A
Rated voltage: 500 V
Fuse type: gF (fast-acting, semiconductor-capable)
Form factor: NH2 size compatible with NH fuse bases
Application class: overcurrent and short-circuit protection in industrial/commercial systems
How to use
Install the fuse insert into a matching NH2 fuse holder or switchgear compartment that accepts NH-form fuses, ensuring the supply is isolated before replacement. Verify correct orientation and secure seating according to the equipment manufacturer’s instructions. After installation, restore power and confirm proper coordination with upstream and downstream protective devices. For safe handling, follow standard electrical safety procedures and use appropriate personal protective equipment when working on live distribution systems.
Usage recommendations
Verify selectivity and short-circuit breaking capacity with the system’s protective device coordination study before replacing fuses. Use this gF fast fuse for circuits with semiconductor loads or where rapid disconnection of fault currents is necessary; avoid using it in circuits requiring delayed tripping for motor startup unless coordination allows.
