Scope of application
The main features of the NH3 indicator fuse system are: 1. Due to a noticeable change in color from red to white, the combination indicator light signal fuse has been turned off. 2. Due to the use of insulated handle terminals, the safety during replacement is higher. NH3 With indicator fuse links provide reliable protection for low-voltage electrical systems, preventing short circuit events with low expected fault currents. Suitable for various applications, including motors, transformers, low-voltage networks, distribution boards, and control circuits.

Here are some precautions:
Equipment protection: In addition to protecting personal safety, fuses are crucial for protecting electrical equipment from damage caused by overcurrent. By disconnecting the circuit before the current reaches a level that could potentially damage the components, fuses can help extend the lifespan of electrical equipment and prevent expensive repairs or replacements
Working conditions
Normal working conditions and correction parameters
The fuse operates under the following normal usage conditions and does not require additional modifications.
When exceeding normal usage conditions, if within the allowable usage range, some parameters may need to be adjusted or consulted. If it exceeds the allowed usage conditions,
You should consult our company and conduct a job adaptability assessment and testing of the conditions. The recommended long-term current value should not exceed 80% of the rated current.
Ambient air
normal condition
-5 ℃ to 40 ℃.
Permitted conditions for use
-40 ℃ to 120 ℃.
Installation, use, and maintenance of fuses
Fuses should be installed indoors or in cabinets that are not affected by rain or snow, and should not be exposed and installed in easily accessible areas. When installing the fuse, it should be ensured that the electrical clearance is greater than 10mm and the creepage distance is greater than 20mm.
