Description

ZELLWEGER BAS98ATEX3008X OTB122 Explosion-proof Junction Box

Product Dimensions：

The Zellweger (Honeywell / Bartec) OTB122 is a high-performance, explosion-proof junction box designed for use in hazardous areas. It is frequently used with Zellweger/Honeywell Analytics gas detection systems (such as the Sensepoint series) to provide a secure, ATEX-certified interface for electrical connections.

Below is the detailed product specification and guide in English.

1. Product Description

The OTB122 (often associated with the certificate BAS98ATEX3008X) is a glass-fiber reinforced polyester (GRP) terminal box. It is specifically engineered for “Ex e” (Increased Safety) environments. Its robust, anti-static construction ensures it can withstand harsh industrial conditions, including offshore platforms and chemical plants.

2. Technical Parameters

3. Key Advantages

• Corrosion Resistance: The GRP material is highly resistant to saltwater, chemicals, and UV radiation, making it superior to metal boxes in corrosive environments.

• Anti-Static Properties: The enclosure is made of anti-static material (surface resistance <$10^9$ $\Omega$) to prevent spark risks from static buildup.

• RFI/EMI Shielding: Often supplied with an internal zinc-plated steel earth continuity plate, which provides excellent grounding and improves immunity to Radio Frequency Interference.

• Mechanical Durability: Impact resistance energy > 2 x 7 Nm, ensuring it doesn’t crack or fail under physical stress.

• Thermal Stability: Rated for extreme low temperatures ($-55$°C), suitable for arctic or high-altitude applications.

4. Product Application

The OTB122 is a universal junction box primarily used in the oil, gas, and chemical industries.

• Gas Detection Systems: The primary interface for connecting Honeywell Sensepoint, Searchpoint Optima Plus, or XNX gas detectors.

• Hazardous Zone Wiring: Serves as a distribution point for electrical circuits in Zone 1 and Zone 2 hazardous areas.

• Industrial Automation: Housing for small PLC terminals or relay connections in explosive atmospheres.

5. Important Precautions (Notes)

• Do Not Open When Energized: To prevent explosions, never open the lid while the internal circuits are live.

• IP Rating Maintenance: Ensure that all unused cable entries are sealed with ATEX-certified blanking plugs and that the silicone O-ring seal is intact before closing the lid.

• Temperature Limits: The standard T6 rating applies up to $+40$°C. If the ambient temperature exceeds this, ensure the power dissipation inside does not exceed 1.2W to maintain safety.

• Thread Compatibility: While the OTB122 usually features M20/M25 entries, always verify the thread type of your glands or sensors (NPT vs Metric) to avoid damaging the housing.
