Suitable for Zone 1 and Zone 2 locations with explosive gas atmospheres.
Suitable for explosive gas atmospheres of Groups IA and IIB.
Suitable for Zone 21 and Zone 22 locations with combustible dust atmospheres.
Suitable for combustible dust atmospheres of Groups IIIA, IIIB and IIIC.
Suitable for temperature classes T1 to T6 (T4).
Widely used in hazardous environments such as petroleum exploitation, oil refining, chemical industry, textile, military industry, as well as offshore oil platforms and oil tankers.
The enclosure is die-cast from aluminum alloy or welded from steel plate or stainless steel, with surface treated by high-voltage electrostatic powder spraying.
This series is available in two structures:
a) Composite structure: flameproof main chamber and increased-safety wiring chamber;
b) Flameproof structure, with 6 specifications for users to choose from.
The aluminum alloy enclosure adopts a modular design, allowing free combination of various circuits.
Equipped with high-breaking miniature circuit breakers or moulded case circuit breakers, which can be switched on and off by operating the handles on the enclosure cover.
Fitted with power-on signal indicators.
Provided with overload and short-circuit protection. Products with earth-leakage protection can be manufactured according to user requirements.
It can be used for power distribution and switching of lighting circuits or power circuits separately, or for both at the same time.
Supports steel pipe wiring or cable wiring.
The optimal solution can be selected according to user requirements and manufactured after confirmation.
Please specify any other special requirements.
If you need to order a BXM(D) explosion-proof lighting (power) distribution box with 4 branch circuits, 20A branch current, equipped with a main switch of 100A, bottom entry and bottom exit, with 1 cable entry of G1 1/2" and 4 entries of G3/4", the ordering model is:
BXM(D)-4/20K100×1G11/2×4G3/4
Explosion-proof marking: Ex db eb IIB T6 Gb; Extb IIIC T80℃ Db
When ordering, please clearly indicate the current corresponding to the number of branch circuits, the quantity and corresponding direction of cable entries and exits.
If a main switch is required, please specify its current rating. If earth-leakage protection or special instruments are needed, additional explanation is required.
Generally, users must provide the electrical schematic diagram.
