Mechanical Interlock A 63A/4P – 5110 (IP67 400V) is a high-reliability safety interlock socket for three-phase industrial circuits. Adopting a 3P+E 4-pole structure and a 63A high-current bearing design, it conforms to the 400V three-phase industrial power standard. It can stably meet the power supply needs of heavy-duty equipment that does not require a separate neutral line, such as intermediate frequency furnaces, high-power fans, and industrial compressors, ensuring the stability and safety of power transmission in continuous high-load operation scenarios.
Its core two-way mechanical interlock design is the key to safety protection. When the switch is in the closed and powered-on state, the mechanical latch will firmly lock the plug, forcing to prevent live plugging and unplugging operations, and avoiding equipment damage or casualties caused by strong electric arcs under high-power conditions. When the plug is not fully inserted and locked, the circuit switch cannot be closed to supply power, fundamentally eliminating hidden dangers such as local overheating and short circuits caused by poor contact. Meanwhile, the device supports a padlock function, which can be fixed in the power-off state during equipment maintenance to prevent unauthorized personnel from mistakenly closing the switch, complying with the safety management specifications of industrial scenarios.
Complying with the EN/IEC 60309 – 2 international standard, the product shell is integrally injection-molded with high-strength flame-retardant engineering plastic, combined with a thickened polyurethane sealing gasket to achieve IP67 dust and water resistance rating. It can completely isolate the intrusion of industrial dust and work normally even in short-term immersion or high-pressure water spraying. The device has passed multiple rigorous tests such as temperature rise test and glow wire test, can withstand a wide temperature range of -20℃ to 60℃, and has excellent anti-vibration performance. The terminals adopt screw-fastened connection, ensuring firm wiring without easy loosening. It is widely used in heavy machinery workshops, outdoor industrial base stations, metallurgical auxiliary equipment and other scenarios, providing long-term safe power supply guarantee for high-power equipment under complex working conditions.
