Niger explosion-proof distribution box models and specifications

Explosion-proof distribution boxes in Niger include HRMD91, HRMD92, HRMD96 series, and PXT/PZ/GCK/GGD models, with stainless steel or aluminum enclosures, flameproof ratings, and customizable configurations.

HRMD Series Overview

HRMD91, HRMD92, and HRMD96 are flameproof distribution boxes designed for hazardous environments:

• Enclosure Materials: HRMD91 uses copper-free aluminum with powder coating; HRMD92 and HRMD96 use 316L or 304 stainless steel for corrosion resistance and durability .
• Flameproof Ratings: HRMD91/92/96 are rated Ex d IIB+H2 or Ex db IIC T6…T41, suitable for gas and dust hazardous zones .
• Design Features: Specialized hinge structures prevent damage to flameproof joints during opening/closing, extending service life. Boxes can be combined or installed freely to save space .
• Internal Components: Can include MCBs, MCCBs, AC contactors, thermal relays, PLCs, soft starters, meters, pushbuttons, indicators, and surge protectors. Custom configurations are available based on user requirements .
• Cable Entry: Optional cable glands; DQM-II (Ex d) or DQM-III (Ex d) recommended. Users must specify direction and size of cable entries .

Other Standard Models

Explosion-proof distribution boxes also include:

• GCK, GCS, MNS: Low-voltage withdrawable switchgear cabinets.
• GGD, GDH, PGL: Low-voltage fixed switchgear cabinets.
• XZW: Comprehensive distribution box.
• ZBW: Box-type substation.
• XL, GXL, XF: Low-voltage distribution cabinets and construction site boxes.
• PZ20, PZ30, PZ40, XDD(R), PXT(R)K-X/X-X/X-X/X-IPX: Terminal lighting, metering, and surface-mounted or concealed distribution boxes . Specifications for these models include:
• Voltage Levels: 220V, 380V, or customized.
• Rated Current / Short-Time Withstand Current: e.g., 250A/10kA, adjustable per customer requirements.
• Installation Types: Vertical, hanging, concealed, or exposed.
• Protection Levels: IP30 or higher depending on model and main switch type.
• Outlet Circuits: Single-phase or three-phase, configurable (e.g., 3 single-phase circuits, 3 three-phase circuits).

Customization and Compliance

• Boxes can be customized for terminal arrangements, internal components, and cable entry sizes.
• All models conform to explosion-proof standards and are suitable for industrial, mining, and hazardous environments.
• HRMD series and other models allow remote or local control of motors, circuits, and monitoring devices . These options provide flexibility for Niger-based installations requiring high safety standards, durability, and adaptability in explosive or hazardous zones.
