GLD automatic transfer switch / Load breaker switch/ Isolating switch (ATS) integrates switch and logic control, it doesn't need adding the controller. It really realizes that the mechanical-elec - trical integration. This automatic transfer switches/load break switches/ ATS has many functions like voltage test, communication inter - face, electrical and mechanical inter - locking, even it also can run automatic control, electromotion remote control and urgent manual control. To realize the operation by managing the motor, transmission box running with each logical order of logical control board, the motor drives switch spring energy storge, Accelerate mechanism with instantaneous release can make and break or transfer the circuit. It realizes the safe isolation through the obvious visual state, thus, it extremely im - proves each electric performance and mechanical performance. Metal housing for bellow 100A switch is very smart and firm. Above 125A switch, whose control part is metal housing, and switch part is adopted glass fiber unsaturated polyester resin to make the housing, it has advantage of strong dielectric performance, guard capacity and reliable operation. The Automatic transfer switch/Load breaker switches/ ATS is suitable for automatic transfer between main power and back - up power of power supply system, or automatic transfer and safe isolation be - tween two load devices. Because the switch owns the merits of graceful appearance, novel, simple, small voume and complete function, it is best selection among the same products. The ATS switch has three poles, four poles (three poles + switch neutral pole) It is divided 11 current grades like 32A, 40A, 63A, 80A, 100A, 125A, 160A, 200A, 250A, 400A, 630A
