Safety & Performance Features

Safe Disconnect Mechanism: Each phase is electrically separated inside flameproof chambers, ensuring the circuit opens before external contact exposure, significantly mitigating arc/flame risks
Short-Circuit Resilience: Designed for high fault protection—20 kA interrupting capability (common operation reference around 10 kA)
IEC Standard Keying & Color Coding: Yellow coding and keyed receptacles prevent mis-mating with incorrect voltage systems; the socket only accepts ATX plugs, ensuring compatibility and avoiding misuse
Compatibility with IEC 309: ATX plugs and sockets can safely mate with standard IEC 309 devices in non-hazardous zones when required

Typical Applications

The PRE316MY is ideal for use in classified environments and portable electrical equipment across industries including:

Lighting rigs, compressors, pumps, heaters, conveyor drives, and motor generators in petrochemical, offshore, and mining environments
Operating under corrosive, damp, or dusty conditions thanks to its sealed design and impact-resistant materials
Situations requiring frequent plug/unplug cycles where safe disconnect is critical
