Carbon steel plate explosion-proof distribution box model

Carbon steel explosion-proof distribution boxes are available in wall-mounted or floor-standing models, certified for hazardous zones 1, 2, 20, 21, and 22, with ATEX and IECEx compliance.

Key Features

Material and Construction: These distribution boxes are typically made from welded carbon steel plates, providing robust mechanical strength and resistance to impact. Surface treatments such as painting or plastic spraying enhance corrosion resistance and durability in harsh environments. Some models can also be manufactured in stainless steel or aluminum depending on specific requirements . Explosion Protection and Certification: Carbon steel distribution boxes are designed for explosive gas mixtures (Class IIA, IIB, IIC) and explosive dust mixtures (Zones 20, 21, 22). They comply with ATEX and IECEx standards, ensuring safe operation in hazardous areas . These enclosures are suitable for both indoor and outdoor installations. Installation Options: Models are available in wall-mounted or floor-standing configurations. They support steel pipe or cable wiring and can accommodate overload, short-circuit, and optional leakage protection functions . Customization and Accessories: Many manufacturers offer customizable internal layouts, allowing for the installation of control devices, motor starters, switches, and terminal blocks. Cable entry points are flexible, and enclosures can be fitted with earthing terminals for secure grounding . Some models also allow for pre-assembled components for immediate commissioning. Temperature and Environmental Resistance: Carbon steel explosion-proof boxes are designed to operate reliably across a wide temperature range and withstand harsh environmental conditions, including dust, moisture, and mechanical stress .
