CZ CZ0253 Explosion-proof Cable-Mounted Socket, All-Plastic, 10-150A, Ex de IIC T6 Gb, IP65

CZ0253 Explosion-proof Cable-Mounted Socket, All-Plastic, 10-150A

The Chuangzheng CZ0253 series explosion-proof cable-mounted socket is an innovative and highly secure solution for flexible power connections in hazardous industrial environments. Constructed entirely from high-strength engineering plastic through a single injection molding process, this device offers exceptional corrosion resistance, superior impact strength, and a significantly lighter weight compared to traditional metallic counterparts. It holds an advanced Ex de IIC T6 Gb explosion protection rating, certifying its safe and reliable operation in areas with highly flammable gases of explosion group IIC, as well as combustible dust zones (Zone 21 and Zone 22). Available in a broad spectrum of current ratings from 10A to 150A and various pole configurations, the CZ0253 is designed to provide versatile and uncompromised safety for portable equipment and extension applications where robust, explosion-proof, and flexible power access is required.

Key Features:

• Advanced Explosion Protection: Boasts an "Ex de IIC T6 Gb" rating, ensuring safe deployment in Zone 1 and Zone 2 gas hazardous areas (including highly flammable IIC gases like acetylene and hydrogen), and Zone 21 and Zone 22 dust hazardous areas. The "de" protection signifies a flameproof enclosure coupled with increased safety terminals.
• All-Plastic, High-Strength Construction: Manufactured from premium engineering plastic, delivering excellent chemical and corrosion resistance, high mechanical durability, and a lightweight profile that simplifies installation and handling in challenging industrial settings.
• High IP65 Environmental Protection: With an Ingress Protection rating of IP65, the socket is fully protected against dust ingress and resistant to low-pressure water jets from any direction, guaranteeing robust performance in wet, dusty, and harsh conditions.
• Wide Current & Pole Configurations: Available in a diverse range of current options (10A, 15A, 25A, 32A, 63A, 100A, 150A) and pole arrangements (2-pole + Earth (2P+E), 3-pole + Earth (3P+E), and 3-pole + Neutral + Earth (3P+N+E)) to suit various power requirements.
• Integrated Safety Interlock: Incorporates a critical safety interlock mechanism that prevents connection or disconnection under live conditions, thereby eliminating the risk of electrical arcing in potentially explosive atmospheres.
• Temperature Class T6: Certified to Temperature Class T6, guaranteeing that the maximum surface temperature will not exceed 85℃ during operation, which is critical for environments containing gases with very low ignition temperatures.
• Flexible Cable Entry: Designed with G-thread cable entries featuring specific applicable cable diameter ranges to ensure secure, flameproof, and dust-tight connections for various cable sizes.
