Thermostats are generally composed of two parts: temperature detection and temperature control. Most thermostats also have alarm and protection functions.

HGC series connecting constant power heating cables use core conductor as heating element.

Cover material: (316L) stainless steel, (CU) copper, (AL) 825 alloy, (CN) copper-nickel alloy

Sheath material: (316L) stainless steel, (CU) copper, (AL)825 alloy and (CN) copper-nickel alloy.

The FDH-40-E kit is designed to connect power to three domestic and imported industrial parallel heating cables for use in hazardous areas. It also has the function of connecting the kit and the insulation layer. The rugged bracket protects the heating cable and can be used with 100mm insulation. No heat gun or blowtorch is required to install the core sealing sleeve (no hot work permit required). The non-curing sealant in the sealing sleeve (no silicone) makes installation and maintenance very simple. Product Specifications: Applicable electric heating cables: domestic brand heating cables, imported series heating cables. Protection grade: IP66, Installation temperature: -50ºC, Working voltage: 277Vac, Working current: 40A, Optional LED indicator: red/green (working voltage: 100~277Vac, power <1W), Product model: Without indicator light: FDH-40-A, FDH-40-E, FDH-40-EP, With LED indicator light: FDH-40-L-A, FDH-40-L-E, FDH-40-L-EP, Qingqichen Electric Heating----As a leader in the field of electric heating, please contact Qingqichen Company for specific design, selection and engineering services of electric heating systems.

FDH-40-C is a power junction box for hazardous areas. This single-inlet junction box is used to connect power cables, heating cables and cold end cables. Depending on the system configuration, the junction box can accommodate one heating cable/cold end cable and one power cable. Cable connections are made via DIN rail-mounted cage clamp terminals. The junction box can be fixed to the wall or to a pipe using four mounting holes on the bottom of the box. Use one of the standard brackets (stainless steel brackets) to fix the pipe.
Parameter Meaning
Rated voltage refers to the maximum voltage value at which the junction box can work stably for a long time. AC 220V/380V means that the junction box is suitable for single-phase or three-phase AC 220V or 380V circuits.
Rated current refers to the maximum current value at which the junction box can work stably for a long time. 40A means that the maximum current suitable for the junction box is 40A.
Cable nozzle thread refers to the thread specification at the cable entrance of the junction box. G1/2 means that the junction box is suitable for cables with an outer diameter of 1/2 inches.
Explosion-proof mark Indicates the explosion-proof performance of the junction box. EⅡCT4 means that the junction box is suitable for factory explosive gas mixture environment. T4 represents the temperature group.
Protection level Indicates the protection capability of the junction box. IP66 means that the junction box has good dust and water resistance.

The HYB-JS warning sign is designed to be attached or hung on the outer surface of completed construction of the heat trace pipeline.

Product introduction:

The explosion-proof temperature controller is an important accessory of the electric heating system, used to control the temperature of the heating medium, and is used in conjunction with the CH type general explosion-proof junction box. It is designed and manufactured according to the requirements of explosion-proof electrical appliances, and the explosion-proof mark is: “Exd e mb llCT4 Gb”;  its shell is DMC plastic with the characteristics of light weight, high mechanical strength and strong corrosion resistance.

The explosion-proof temperature controller is used for the connection of the power line and the electric heating belt in the explosion-proof area. Usually fixed on the pipe. After being matched with electric heating belt and power junction box, it is suitable for use in the explosive gas mixture T4 group field in the first and second areas of the factory. The explosion-proof temperature controller can output in one direction, and its shell is made of DMC plastic.

The HYB-JS warning sign is pasted or hung and fixed on the outer surface of the heat tracing pipeline after construction, as a signal and a power-on warning. Generally, warnings are pasted or hung at easy-to-see locations every 20m or so.
