IEC NH FUSE-LINKS

FEATURES & BENEFITS

• Dimensions according to DIN 43
620 parts 1 to 4
• Non-isolated gripping lugs
• Double indicator
• Lead free contact blades
• 0% cadmium

APPLICATIONS
• gG: general purpose cable and line
protection

The NH system is classified among plug-in fuse systems and is STANDARDS

composed of: • VDE 0636 Part 201
• fuse-base (possibly including terminal covers and phase barriers) • IEC 60269-1 and -2

• fuse-link with blade contact

MERSEN reserves the right to change, update or correct, without notice, any information contained in this datasheet.
• fuse-link replacement device (LV HRC fuse puller)
Since the design of this system cannot guarantee
non-interchangeability of rated current it must be handled by a
qualified professional.

Type “gG” NH fuse-links are full range breaking capacity fuse-links

and are used to protect cables and equipment. They can interrupt
any current surge, from the lowest fusing current up to their breaking
capacity, and so can be used alone as protection. They also protect
electrical devices and industrial set-ups from the electrodynamic
effects of very high short-circuit currents.
