Description
HMKM1EL 1. Product Overview

This type of controller is applicable to three-phase four wire auxiliary power supply environment. The rated insulation voltage is 800V, which is suitable for infrequent switching and infrequent motor starting in circuits with AC 50Hz, rated working voltage of 400V and rated current of 1250A. The circuit breaker has overvoltage protection, undervoltage protection, phase failure protection, overload long time-delay inverse time limit, short circuit short time-delay inverse time limit, short circuit short time-delay definite time limit, short circuit instantaneous and undervoltage protection, and leakage tripping protection functions, which can protect lines and power equipment from damage.

The product meets the standard GB 14048.2.

2. Product features:

2.1. Protection function:

It has overvoltage, undervoltage and phase loss protection functions; Current overload, short circuit short delay, instantaneous protection and leakage tripping protection functions.

2.2. Display function:

12864 dot matrix OLED LCD display, friendly Chinese human-computer interaction interface.

Automatic wheel display of current three-phase voltage, three-phase current, residual current, rated leakage current, rated current, overvoltage and undervoltage and other parameters.

2.3. Setting and Query Functions:

Enable and disable overvoltage, undervoltage, phase loss, current overload long delay, short circuit short delay, instantaneous protection and leakage current protection functions can be set by pressing the key.

The main parameters such as overvoltage, undervoltage, phase loss, rated current, overload long delay time, short-circuit short delay multiple, short-circuit short delay time, short-circuit instantaneous multiple, residual current, and residual current delay time can be set by pressing the key.

Many parameters such as trip times can be queried by pressing the key.

The above functional parameters can also be viewed and set through the communication interface.

2.4. Control function:

It can remotely view the working status, view parameter settings, modify parameter settings, control shunt tripping and other functions through the communication interface.

The synchronous shunt function of the circuit breaker can be realized through the external breaking interface.

2.5. Monitoring and recording function:

Accumulate the number of protection trips, and record the number of different fault trips.

2.6. Auxiliary functions:

MODBUS molded case circuit breaker communication protocol; Communication protocols can also be customized according to customer requirements.

2.7. Performance and process

The circuit board is made of highly integrated industrial materials and advanced lightning protection design, which fully meets the requirements of electromagnetic compatibility in GB14048.2-2008 standard.

The circuit board adopts compact structure design, which is suitable for users' requirements for compact space in the circuit breaker.

The process of the circuit board is neat, beautiful, and the wiring is convenient. Only the necessary signal input wiring is required.

It can be directly assembled without secondary debugging. After assembly, simply press the key to calibrate the voltage, current and leakage current (the whole set of transformer can be directly used without calibration).

The product basically includes the functions of the current electronic molded case circuit breaker.

It can be designed and developed according to the structure (or original circuit board) of the customer's prototype according to the customer's needs.
