Product Description

The 8571 series is a part of R. STAHL’s SolConeX range. This specific model is a 4-pole, 5-wire (3P + N + PE) wall-mounted socket. It features a built-in load-disconnect switch, meaning the socket is only energized when the plug is fully inserted and rotated, providing an extra layer of safety.

• Key Feature: Integrated load-breaking capacity (AC-3 according to IEC/EN 60947-3).

• Material: Made of high-quality, glass fiber reinforced polyester resin for extreme durability in corrosive environments.

Product Parameters

Product Advantages

• High Safety (Load Disconnect): The integrated switch ensures that the socket is not live until the plug is locked. This prevents arcing when plugging or unplugging under load.

• Extreme Durability: The housing is resistant to chemicals, UV radiation, and mechanical impact, making it ideal for offshore or heavy industrial use.

• Self-Cleaning Contacts: The socket uses laminated contacts that stay clean over time, ensuring low contact resistance and preventing overheating.

• User-Friendly Design: Features large, clearly marked terminals for easy wiring and a padlockable handle to prevent unauthorized use.

Product Application

This socket is widely used in industries requiring explosion protection:

• Oil & Gas: Offshore platforms, refineries, and LNG terminals.

• Chemical & Pharmaceutical: Plants where flammable gases or dusts are processed.

• Marine: Shipyards and vessel engine rooms.

• Heavy Industry: Paint shops, grain silos, and fueling stations.

Important Notes & Precautions

• Plug Compatibility: This socket must be used with a compatible 8571/12 series plug to maintain the Ex-rating and locking functionality.

• Installation: Ensure the cable glands used for entry are also Ex-rated and maintain the IP66 seal.

• Temperature Limits: Be aware of the ambient temperature range (typically -30°C to +40°C or +55°C depending on the T-rating) to avoid de-rating the current.

• Maintenance: Periodically check the seal and the locking mechanism to ensure no dust or moisture has bypassed the enclosure.
