Product Description

LW5-40A/3P 360 Changover switch

Technical specifications

Rated insulation voltage: 500V.

Conventional heating current: 16A.

Mechanical life: generally up to 0.3 × 10⁶ times and above, operating frequency of 300 times/hour.

Electrical life: 0.1×10⁶ times at AC-15, DC-13, operating frequency 300 times/hour; 0.1×10⁶ times at AC-3, operating frequency 120 times/hour; 0.1×10⁶ times at AC-4, operating frequency 120 times/hour.

Product structure

Contact system: There are 1-16 sections according to the number of sections of contact system, 16 kinds in total, each double-break contact group of the same changeover switch is electrically separated, and each double-break contact group can control an independent electric circuit.

Actuator shape: There are two types: Ball type and Knob type, which can be selected according to different operating habits and usage scenarios.

Operating mode: There are two types of actuator: self-locking type and self-recovery type; the self-recovery type handle will automatically return to the original position after operation, while the positioning type handle will remain in the position after operation.

Advantages of the product

Various control functions: It can realize various control functions of electrical equipment, such as forward and reverse, variable speed, etc., to meet different application requirements, and through 360-degree steering operation, it can flexibly switch the circuit state and realize complex control logic.

High reliability: Complying with relevant standards such as GB 14048.5, it has a long mechanical and electrical life, and can work stably and reliably for a long time, reducing the cost of equipment maintenance and replacement.
