Specific parameters of explosion-proof distribution boxes

Thread Content

Specific parameters of explosion-proof distribution boxes I. Scope of application 1. Hazardous areas in Zone 1 and Zone 2； 2. Explosive gas environments of categories IIA, IIB, IIC with temperature group T4 ； 3. Suitable for areas with flammable dust ； 4. Suitable for both indoor and outdoor use. II. Meaning of model codes: BX M D 51-□/□ □□ □ □ □ □ □ □ □ WF1 – Outdoor use, resistant to corrosion; specifications for outlets, number of outlets, direction of outlets; specifications for input ports, number of input ports, direction of input ports; current rating of the main switch: K – Main circuit equipped with a main switch; number of branch circuits; design sequence number; power supply, lighting; explosion-proof distribution box.

III. Main parameters: Corrosion resistance rating, rated current (A), rated voltage (V); explosion protection mark in the explosion-proof distribution box; number of branch circuits; protection rating: WF110-400220/380ExdIIBT4; 4, 6, 8, 10, 12; IP65.

IV. Product features: 1. This product features an explosion-proof structure, with a welded steel shell and a surface treated by electrostatic spraying ； 2. It is equipped with internal components such as high-breaking-capacity miniature circuit breakers or molded-case circuit breakers, AC vacuum contactors, motor protectors, and voltage meters, and offers protection against overload, short circuit, under-voltage, phase loss, and electric leakage. 3. Both the incoming and outgoing wires use spark-free explosion-proof plug-in devices, and there are clear device tag plates. These plates are made by bending 304 stainless steel sheets and are polished, giving them an attractive and practical appearance. 4. A special processing method is used for the flameproof surface, with an oil-resistant and aging-resistant silicone \"O\"-ring embedded therein, thereby achieving an IP65 protection rating for the enclosure. This solves the problem of rainwater intrusion in traditional flameproof enclosures when used outdoors, eliminating the complicated and ineffective measures that rely on rain covers to prevent rain. 5. All fasteners are made of 304 stainless steel, which is resistant to severe corrosion. 6. The specific functions and appearance can be customized according to user requirements. V. Ordering Instructions: When placing an order, the user must specify the number of circuits in the distribution box, the current per circuit, and the number of poles of the circuit breakers. If a main switch is included, its operating current and number of poles must also be specified. In addition, the direction, quantity, and size of the incoming and outgoing wiring connections must be indicated. If lighting, power, and leakage are combined, a schematic diagram must be provided.
