Overview
The QT3B series master controller is mainly used in control circuits with AC 50HZ (60HZ) rated voltage of 380V (440V) and below, to control the motor starting, speed regulation, braking, commutation and other special functions of lifting and transportation machinery, and can achieve dual mechanism linkage operation. All types of integral linkage platforms can be made into rotary type. Different seats can be selected for different usage environments. This series of linkage consoles has been widely used in various types of mechanical equipment in industries such as ports, water transportation, railways, metallurgy, mining, electricity, construction, etc.
[Standard]: IEC439 "Complete Sets of Low Voltage Switchgear and Control Equipment"; JB/T6748-1993 "Crane Control Console"
The QT3B type is mainly used for conversion in AC 50HZ (60HZ) rated voltage 380V (440V) and below power transmission devices, and can be widely used in small and medium-sized cranes to directly control motor starting, speed regulation, braking, and direction.
structural characteristics

The linkage platform is installed as a whole, using engineering plastic injection molding, with a beautiful and elegant appearance and compact structure. Equipped with WKL3 type master controller, it has clear hand feel, clear gear position, zero position self resetting and locking device, and easy component wiring, disassembly, and maintenance. Each institution can install potentiometers, and the panel is equipped with various indicator lights and control buttons. All use Schneider contacts, ensuring safe and reliable operation with a long service life. This product has strong universality and wide applicability, and can be widely used in various types of lifting and transportation equipment.
