TXHGL Load Isolation Switch (also known as load disconnector) is developed by the company using European advanced technology, is the ideal replacement products in similar products. HGL Load Isolation Switch is widely used in the distribution system and automation systems of the construction, power, petrochemical and other industries. Load disconnector has modular design structure, flexible combinations, use glass fiber reinforced unsaturated polyester resin to produce casing, with high dielectric properties, protection and reliable operational safety. Operating mechanism is the acceleration mechanism of the spring storage and instantaneous release, with the double breakpoint contact structure of instantaneous making and breaking. Unrelated to the operating handle speed, greatly improving the electrical and mechanical performance. A variety of structure and operation mode, with the window of direct observation of the contact state, the operations inside or outside of cabinet, there are positive and side operation, a board wiring. Switch has nice, novel and concise appearance, small size, full-features, is the ideal choice for similar products,
TXHGL load isolation switch for the industrial power distribution equipment of AC 50Hz, rated voltage of 660V, DC voltage of 440V, the conventional heating current of 3200A, used for infrequent making and breaking of circuit and electrical isolation, switch of more than 1000A is only used for electrical isolation, widely used in the distribution system and automation systems of the construction, power, petrochemical and other industries.

HGLC side load isolation switch, increases a side operating mechanism HGL on the basis of HGL load disconnector, used for making and breaking of circuits and electrical isolation.

HGLZ switching load isolation switch is composed of two HGL load isolation switch of up-down stacking or left-right paralleling, for breaking of two-way power supply or conversion of two load equipment and security isolation. Load disconnector meets IEC60947-3, GBI4048.3 standards. Load disconnector has nice, novel and concise appearance, small size, full-features, is the best choice for similar products

HGL-160A / 4Z2JF11 ~ 380V In 125A switching load disconnector, left-right arrangement. AC rated voltage of 380V, conventional heating current of 160A,rated current of 125A, 4-pole, operation outside the cabinet, auxiliary contacts, 1 normally open +1 normally closed.

■ Accelerator of instantaneous release of the spring energy storage achieve fast making or breaking (13.8m/s), unrelated to the operating handle speed, greatly improves arc extinguishing capacity
■ Casing made of glass fiber reinforced unsaturated polyester resin has good flame-retardant properties, dielectric properties, carbonization resistance and impact resistance
■ Parallel double-breakpoint contacts have self-cleaning function
■ All contacts have two separate contact faces. Isolation distance is long, in the "0" position, three locks lock handle at the same time, reliable to avoid misoperation.

TXHGL-63~3150A Load isolation switch

■ TXHGL load isolation switch of 63A ~ 3150A is divided into seven specifications, is the basis of modular design, have three-pole, four-pole (three-pole+neutral pole can be on or off), mainly for on and off of the circuit or electrical isolation, rated current of 1000A and above only for electrical isolation
■ The front side is equipped with marking window indicating that the contact is on and off
■ Can provide rear observation window according to the need, to observe directly the on-off state of contact
■ Can be equipped with two sets of auxiliary contacts

Direct operation: the handle is installed directly in the middle of the load disconnector
Operation outside the cabinet: the handle is installed outside the distribution cabinet
