KJT brand high temperature resistant travel switch is a fully enclosed contact switch made of high temperature resistant materials. One group is normally open and the other is normally closed. The maximum allowable current is 5A/AC 220V (other voltages are subject to reservation). The contacts are specially processed After treatment, it can be used in high temperature environments for a long time without being damaged by oxidation or contamination.
KJT-XW series high temperature resistant travel switches have a maximum temperature of 350°C and can be divided into more than ten specifications such as roller arm type, adjustable rod type, pressure plunger type and roller pressure column type, which can meet the requirements of different occasions. Widely used in electric power, chemical industry, petroleum, textile, steel and other industries.

Note:
1. The power factor of the inductive load is above 0.4 (AC), and the time constant is below 7msec (DC).
2. The inrush current of the light bulb load is 10 times the steady state current, and the inrush current of the motor load is 6 times the steady state current.
