Trusted Supplier of Appleton™ PRE316FP 16A Flush Sockets

Sensor Control LLC is a trusted distributor of Appleton™ ATX™ PRE Series 16 Amp flush sockets (PRE316FP) in the UAE. These sockets are engineered to deliver increased safety, robust performance, and reliable electrical connectivity in hazardous environments including Zones 1, 2 (Gas), and Zones 21, 22 (Dust). Designed for extreme industrial conditions, they comply with stringent international standards such as ATEX, IECEx, and INMETRO.

Key Features of PRE316FP Socket

1. Safe Disconnect and Contact Isolation
The socket is designed with a safe disconnection mechanism, ensuring power isolation before the plug is removed. This feature reduces arc risks and prevents accidents during disconnection under load.

2. Dual Flameproof Chamber Design
The internal structure uses a dual-chamber flameproof configuration:

• One chamber ensures secure contact separation.

• The second chamber ensures the disconnection of each individual phase, enhancing safety during use.

3. High Short-Circuit Protection
With a short-circuit rating of 20 kA, the PRE316FP socket provides outstanding protection against electrical faults, making it suitable for demanding industrial applications. Normal operating reference is 10 kA.

4. Environmental Durability & Temperature Resistance

• Operating temperature range: -20°C to +55°C (-4°F to +131°F).

• Constructed using high-impact polycarbonate or fiberglass-reinforced polyester depending on the pole configuration.

• The socket body is IP66-rated, ensuring excellent resistance to dust and water ingress.

5. Voltage Coding & Compatibility

• Color-coded for voltage differentiation, preventing mismatched connections.

• The PRE316FP socket only accepts matching ATX plugs, such as the PRE316PB model, ensuring secure and safe connections.
