Class CC fuses are used for “branch circuit protection".

The enclosed fuse holders are designed and tested to comply with the US National Electrical Code NEC 210.20(A). This means that when subject to continuous operation, only 80 % of the rated current is permissible as operational current.

An operational current of 100 % of the rated current (30 A) is only permissible short-time.

The devices are prepared for the inscription labels of the ALPHA FIX terminal blocks 8WH8В 120-7AA15 and 8WH8В 120-7XA05.

There are three different series:

• Characteristic: slow, 3NW1В ...-0HG
  For the protection of control transformers, reactors, inductances. Significantly slower than the minimum requirements specified by UL for Class CC Fuses of 12В s at 2В Г—В I_n.
• Characteristic: quick 3NW2В ...-0HG
  For a wide range of applications, for the protection of lighting installations, heating, control systems
• Characteristic: slow, current-limiting 3NW3В ...-0HG
  Slow for overloads and quick for short circuits. High current limitation for the protection of motor circuits.
