Product Description

Product Description
XRNM series high-voltage current limiting fuses for motor protection are suitable for indoor AC 50 Hz, rated voltage 3.6-12KV systems, and can also be used in conjunction with other protective appliances (such as switches, vacuum contactors, etc.) as protective components for overload or short circuit of high-voltage motors and other power equipment.

Model Description



Product technical parameters and installation size







Product structure features 
1. A fuse is composed of a fuse contact, fuse tube, impactor, filler, etc.
2. The installation method is to directly fasten the busbar with screws from the exposed position, which has the characteristics of small installation volume and reliable contact. Insertion installation can also be provided according to user requirements.
3. When the fault current exceeds the specified value for enough time, the melt will melt and produce an arc. The quartz sand speed level arc, which plays the role of arc extinguishing, will cut off the circuit to protect the motor circuit and power equipment.
4. The product performance meets the national standard GB15166.2 and the international standard IEC60282-1.
5. The melt is made of pure silver strip, which is resistant to aging and has low power consumption.
6. The impactor can indicate a fuse and drive the mechanical switch to trip.
