Overview
The improved control and protection switch appliance is a new category of products in the low-voltage electrical industry. Its product category code is, which is an English control and protection switch appliance. abbreviation of.
The conforming standards "Low-voltage switchgear and control equipment, Part Multi-function Electrical Appliances, Section Control and Protection Switching Appliances" and "Low-voltage switchgear and control equipment, Multi-function Electrical Appliances, Control and Protection Switching Appliances" are equally adopted.
Control and protection switch丨Basic type丨Fan and water pump
Function
The series of products adopts a modular single product structure, integrating traditional circuit breakers, fuses and contactors, overload or overcurrent, The main functions of low-voltage electrical products such as phase failure protection relays, starters, isolators, motor comprehensive protectors, etc., have remote automatic control and local direct manual control functions, panel indication and electromechanical signal alarm functions, and overvoltage and undervoltage functions. The protection function includes phase failure and phase loss protection, undercurrent and underpower function, coordinated time current protection characteristics, and four-stage protection characteristics of overload inverse time limit, definite time limit, short circuit instantaneous, and extra large short circuit instantaneous. By selecting functional modules or accessories as needed, you can control and protect various motor loads and distribution loads, integrating control and protection.
Purpose
The control and protection switch is mainly used in AC power systems with rated voltage up to, rated current up to, adjustable operating current up to, and control of motor power up to, normal conditions including load-carrying and breaking. current under overload conditions, and can connect, carry and break current under specified abnormal conditions such as short circuit.
Product advantages
◇Compared with systems composed of separate electrical appliances
Features of self-coordination of control and protection Series control and protection switch appliances integrate control and protection functions, equivalent to circuit breaker fusing device + contactor + overload relay + auxiliary electrical appliances. It well solves the problem of protection and control characteristic matching between components that cannot or is difficult to solve with separate components, making the protection and control characteristics more perfect and reasonable. It has inverse time limit and instantaneous three-stage protection characteristics as long as it is based on the load power or current. You can correctly select a single product to replace the previous various electrical appliances from the power incoming end to the load end. There is no need to reduce the capacity, which greatly reduces the designer's workload.
It has unparalleled operating reliability and continuous operating performance of the system. It can be put into use without maintenance after breaking the short-circuit current, that is, it has continuous operating performance after breaking the short-circuit fault. After the breaking short-circuit current test is carried out, it can still be put into use. It has an electrical life of not less than 10 times, which is difficult to achieve by systems composed of separate components such as circuit breakers. This feature greatly improves the operational reliability and continuous operation of the system. Among them, the indicators are among the same kind. The product's international leading index is the highest domestically.
Energy-saving materials have the advantages of small size, less installation area, no separate component contacts, reduced circuit heating, energy saving and material saving.

◇Compared with molded case circuit breaker
It has the characteristics of high breaking capacity and short arcing distance. In rated operation, the short circuit breaking capacity reaches high breaking type. For the standard type and the economical type, the breaking time under the expected short-circuit current is only ~, and the current limiting coefficient reaches up to 20%, reaching the leading level of molded case circuit breakers and reaching the current limiting level of fuses, which greatly limits the impact of short-circuit current on the system. dynamic thermal shock. The arcing distance is only ~.
Compared with the protection system composed of plastic case circuit breaker, the thermal trip inverse time limit current and the magnetic tripping time limit current, which have the characteristics of adjustable protection setting current, can be adjusted on the panel, that is, in addition to the conventional In addition to the thermal protection current that can be adjusted according to the load power, the overcurrent protection setting current can also be adjusted on the panel. The adjustment range for the distribution load is ~, and the adjustment range for the motor load is ~. It overcomes the disadvantage that the short-circuit protection setting current of the molded case circuit breaker cannot be adjusted by the user after leaving the factory, so that even if the product is installed at the end of the line and the short-circuit current is small, it still has a good short-circuit protection function.
◇Compared with the performance of contactors, it has the characteristics of long life and convenient operation
The mechanical life is up to ~10,000 times, and the electrical life is ~10,000 times. It can be operated manually on site or automatically at a distance. control function. The advanced separation design of the contacts and the electromagnetic system is adopted, which effectively suppresses the secondary bounce of the contacts, greatly improves the electrical life of the product, and is especially suitable for severe occasions such as heavy-load starting.
Other features
Complete set of accessories: auxiliary contacts and signal alarm contacts, shunt release, remote re-release, door or drawer panel operating mechanism, control circuit conversion module, etc., which can be configured on a single product A complete control and protection unit realizes coordinated control and protection functions.
Flexible installation, horizontal installation, vertical installation and horizontal installation will not affect the performance. It can be widely used in compact complete sets, including fixed or drawer-type cabinets, especially in / and / drawers. It has incomparable advantages that separate components have.
The terminal blocks of the fully reliable protection level high-board front plug-in type rear panel wiring are all anti-touch functions. When equipped with a high protection level shell, it can be applied to wet places in civil buildings, basements, pump rooms, coal mines, ports, shipbuilding, petrochemical and other fields. It is an ideal product to replace the current electromagnetic starter protection type and combined starter.
