Intrinsically safe: The energy of the circuit is limited by the relevant technology, so that the electrical energy generated in the electrical equipment generates sparks or hot surfaces that are not sufficient to detonate substances in the explosive environment.
Increased safety type: Through the design of the product, it can eliminate the detonation source of hot surface or electric arc or electric spark to achieve the purpose of explosion protection.
Molded type: A device or part of a device that may ignite an explosive environment is encapsulated in a substance to isolate the device or part thereof from substances in an explosive atmosphere for the purpose of explosion protection
