The Chuangzheng CZ0251 series represents a state-of-the-art all-plastic explosion-proof plug and socket device, meticulously designed for safe and reliable power connection in hazardous environments. Engineered with a robust engineering plastic enclosure, this device offers superior corrosion resistance, high impact strength, and a lightweight alternative to traditional metal enclosures. Certified with an impressive Ex de IIC T6 Gb explosion protection rating, it ensures utmost safety in areas where highly flammable gases of explosion group IIC are present, as well as in zones with combustible dust. Available in a wide range of current ratings from 10A to 150A and various pole configurations, the CZ0251 series provides a versatile solution for diverse industrial applications demanding uncompromised safety and operational continuity.

Key Features:

• Superior Explosion Protection: Features an "Ex de IIC T6 Gb" rating, certifying its safe operation in Zone 1 and Zone 2 gas hazardous areas (including IIC gases like acetylene and hydrogen), and Zone 21 and Zone 22 dust hazardous areas. The "de" indicates flameproof enclosure and increased safety terminals.
• All-Plastic Construction: Crafted from high-strength engineering plastic, providing excellent chemical and corrosion resistance, mechanical durability, and a light overall weight, ideal for challenging industrial environments.
• High IP65 Environmental Protection: The robust enclosure provides an Ingress Protection rating of IP65, ensuring complete protection against dust ingress and resistance to multi-directional low-pressure water jets, making it suitable for wet and dusty conditions.
• Wide Current & Pole Configurations: Available in multiple current ratings including 10A, 15A, 25A, 32A, 63A, 100A, and 150A, alongside various pole arrangements such as 2-pole with Earth (2P+E), 3-pole with Earth (3P+E), and 3-pole with Neutral and Earth (3P+N+E).
• Safety Interlocking Function: Incorporates a mechanical interlocking mechanism that prevents live plugging or unplugging, significantly enhancing operational safety and preventing electrical arcing in hazardous atmospheres.
• Temperature Class T6: Guarantees that the maximum surface temperature during operation will not exceed 85℃, making it safe for environments with very low ignition temperature gases.
• Robust Cable Entry Design: Designed with standard G-thread cable entries to ensure secure and explosion-proof cable connections.
