Explosion-proof type and grade group level groups: dⅡBT4 or dⅡCT4 dⅡBT6 or dⅡCT6 intrinsically safe level group: When a step change assembly thermal iaⅡBT4 or iaⅡCT4 (more on style) iaⅡBT6 or iaⅡCT6 (more on type) enclosure protection IP65 appeared in temperature Price resistance, heat resistance of the output changes to the equivalent of 50% of the step change, the time required for assembly thermal resistance parameters, known as the thermal response time. Temperature insulation resistance test voltage DC 10-100V any value desirability Assembly thermal resistance how to sell, the ambient temperature in the range of 15-35 ℃, relative humidity should be less than 80%, by armored thermoelectric barrier measuring current maximum of 5mA . Armored thermal resistance Armored thermal response timetable timetable thermal response of thermal resistance Assembly thermal resistance how to sell, Anhui Electric Group (certification), Assembly thermal resistance provided by the Anhui Electric Group Company Limited. Anhui Electric Group Co., Ltd. (www.ahecable.com) is Chuzhou, bare wires and bare conductor products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
