CZ0254 Explosion Proof Plugs and Sockets

Certified for Hazardous Environments | Available in UAE

Sensor Control LLC proudly supplies the CZ0254 Full Plastic Explosion Proof Plug and Socket, a high-performance electrical connection system engineered for use in hazardous locations. Whether in oil refineries, offshore rigs, chemical plants, or industrial processing zones, this unit delivers unmatched safety, superior durability, and ease of operation under demanding conditions.

Backed by IECEx, ATEX, and CCC certifications, the CZ0254 is a globally trusted product that meets the toughest international standards for explosion protection in environments classified as Zone 1, Zone 2 (Gas) and Zone 21, Zone 22 (Dust).

Product Overview

The CZ0254 is a full plastic explosion-proof plug and socket system, designed to handle up to 690V AC and 125A current. Its static-resistant GRP (Glass Reinforced Plastic) housing provides outstanding mechanical strength and resistance to chemicals, corrosion, and UV degradation. This makes it ideal for deployment in offshore, desert, or heavy industrial settings where both safety and reliability are paramount.

The unit includes built-in features like a self-cleaning inserting sleeve, protective covers, and a low-force insertion design for quick, safe, and secure electrical connections. It also supports multiple cable configurations with reliable sealing and dust protection via IP65 ingress protection.

Key Product Features

1. Self-Cleaning Contact Sleeve
   Designed with a self-cleaning insertion system, the CZ0254 ensures low contact resistance, better conductivity, and longer service life. This mechanism automatically scrapes off dirt and oxidation during each plug-in cycle.

2. Protective Cover Design
   Each plug and socket comes with a rugged protective cap that keeps dust, moisture, and debris out when the device is not in use, helping maintain IP65 protection throughout its lifetime.

3. Low Insertion and Withdrawal Force
   CZ0254 is ergonomically designed to ensure easy connection and disconnection even in cold environments or while wearing gloves, reducing fatigue and increasing operator safety.

4. Multiple Global Certifications
   Fully certified with IECEx, ATEX, and China CNEx, this product is approved for use across multiple continents, providing confidence in international projects and procurement.

5. Wide Temperature Range
   Operates reliably in ambient temperatures from -40°C to +55°C, making it suitable for both Arctic and desert applications without performance loss.
