BLJ85 Series Explosion-proof Connector

◆ This Explosion-proof Plugs And Sockets is made of high-performance composite material Copper-free Aluminium Alloy, which is high-strength and corrosion-resistant.
◆ Plugs are classified by the number of poles into 3P, 4P, and 5P.
◆The Flameproof Plugs and Sockets are quipped with interlocking switch, plug can only be pulled out after switching off; and can be switched after inserting the plug .

Q1: How to select the appropriate explosion-proof rating based on my operating environment?
- A: Selection depends on area classification (Zones 0/1/20/21 require Ex d, while Zones 2/22 may use Ex e), explosive substance properties (gas groups and temperature classes), and environmental conditions (IP and corrosion requirements).
Q2: What is the relationship between IP ratings and explosion-proof ratings?
- A: They are independent but equally critical. IP ratings focus on preventing ingress of solids and water, while explosion-proof ratings ensure internal sparks cannot ignite the external atmosphere.
Q3: What are the key precautions for installing explosion-proof connectors?
- A: Installation must be performed by qualified personnel using compatible, properly tightened cable glands and ensuring the enclosure is permanently and reliably grounded.
