The MLHGL series of load disconnect switches – the ideal solution for your industrial power distribution needs.

These switches are designed to meet the stringent requirements of industries such as construction, power, and petrochemicals, combining reliability and efficiency. Rated up to 660V (AC) and 440V (DC) with a thermal current rating of up to 3200A, the MLHGL series is ideal for low-frequency circuit connection and disconnection, as well as electrical isolation. Compliant with IEC60947-3 and GB/T14048.3 standards, these switches ensure safe and efficient operation in any power distribution system or automation device.

MLHGL load disconnect switches feature a modular design for seamless integration into your existing systems. Whether you need to connect or disconnect a circuit, or require electrical isolation, these switches handle it with ease. For applications exceeding 1000A, these switches are specifically designed for electrical isolation, ensuring safe and efficient operation. Their innovative design incorporates two vertically or side-by-side stacked MLHGL load disconnect switches, making them ideal for switching between dual power supplies or safely isolating two load devices.

A key highlight of the MLHGL series switches is their advanced closing mechanism. The spring-loaded, instantaneous-release accelerated closing mechanism, combined with a contact design featuring a parallel double-break contact structure, significantly enhances electrical and mechanical performance. This means you can rely on the fast and efficient operation of MLHGL switches, minimizing downtime and increasing productivity. Furthermore, the use of glass fiber-reinforced unsaturated polyester molding compound ensures the switch’s high dielectric properties and protective capabilities, making it not only robust and durable but also safe and reliable in operation.

The MLHGL series load disconnect switches are designed with user convenience at the core. This series is available in 3-pole and 4-pole configurations, featuring a window on the front indicating the open/closed status of the contacts, and an observation window on the back for easy monitoring. The manual operating handle can be directly mounted on the switch for convenient operation within a cabinet, or it can be operated externally via an extension rod, flexibly meeting your power distribution needs. For further enhanced safety, the handle is secured in the disconnected position with a double locking device, effectively preventing accidental operation. The MLHGL series also offers normally open and normally closed auxiliary contact options and comes with dedicated mounting plates for front and rear wiring, meeting diverse customer needs and making it a leader in its class.

In conclusion, the MLHGL series load disconnect switches are more than just products; they represent a commitment to quality, safety, and efficiency in industrial power distribution. With their innovative design, robust construction, and user-friendly features, these switches are poised to become indispensable components of your electrical systems. Choose the MLHGL series for reliable performance and peace of mind.
