UL认证陶瓷熔断电阻

UL认证陶瓷熔断电阻

项目介绍:

The resistor components consist of fully welded wire wound ceramic resistors, which is a well-known and approved technology.

The base material is corderite, which is a type of ceramic with a very high resistance to temperature changes and the wire is coated with aluminium phosphate to protect the wire and conduct the heat developed in the wire on to the ceramic core. Aluminium-phosphate is stable at 500°C.

The resistor cages comply with IP21 when mounted  vertically (otherwise IP20) giving electrical and thermal protection. The resistors have a nominal load from 430W and upward and are particularly suitable for pulse loads of 10 – 20 times more compared to the nominal load. This is due to the ceramic core material and an extra high weight of wire.
