ZGLEDUN LDM9E(CM1) M-type Electronic Intelligent MCCB Molded Case Circuit Breaker, Manufacturer Smart MCCB with communication functions

Product Description:

ZGLEDUN Series LDM9E（CM1) electronic molded case circuit breaker (hereinafter referred to as MCCB) is suitable to be used for infrequent conversion and infrequent starting of the electromotor in circuits of AC 50Hz/60Hz, rated insulation voltage 800V, rated voltage of not higher than 690V and the rated working current up to 800A. The Electronic MCCB circuit breaker has overload long-delay inverse time functions, short-circuit short-delay inverse time functions, short-circuit short-delay definite time functions, short-circuit instantaneous and under-voltage protection functions, as well as residual current protection functions(optional), lack of phase protection functions (optional). It can protect the circuit and power equipment from damage. The MCCB molded case circuit breaker has complete and accurate protection characteristics which can improve the reliability of power supply and avoid unnecessary power outages.

This MCCB are classified into M type (medium high breaking type) and H type (high breaking type) according to their rated ultimate short-circuit breaking capacity.
The electronic MCCB has the characteristics of small size, high breaking capacity, short arcing, and anti-vibration.
The electronic MCCB can be installed vertically (ie vertical installation) or horizontally (ie horizontal installation).
The circuit breaker has an isolation function.
This MCCB can be customized to suit your needs.

Normal Working Conditions :

Altitude: ≤2000m;
Ambient temperature: -5℃ ~+ 40℃
This MCCB can withstand the influence of humid air, salt mist and oil mist.
The installation category:
Main circuit of the MCCB circuit breaker: III
The other auxiliary circuits and controls T: II

When the maximum temperature is +40℃, the relative humidity of the air does not exceed 50%. Higher relative humidity is allowed at lower humidity. Special measures should be taken for the occasional condensation due to temperature changes. The maximum inclination is 22.5°.
Installation places where there is no explosive medium,no gas and conductive dust that can corrode metal and damage the insulation. Installation places where there is no rain or snow.

The communication interface and external module application and networking of the smart molded case circuit breaker MCCB:

LDM9E (CM1) communicatable intelligent MCCB molded case circuit breaker is equipped with a communication interface, connected to the MODBUS communication interface protocol.

LDM9E (CM1) type communicable intelligent molded case circuit breaker is not used for network communication. When it was used alone, the handheld programmer can perform operations such as setting the protection characteristics of the circuit breaker through the communication interface. It can also be connected to the communication interface with LCD The display module which is used to monitor the operating current and fault information of the circuit breaker. When the LDM9E (CM1) type communicable intelligent molded case circuit breaker is used for network communication, it can be directly connected to the corresponding field bus. For field buses of different protocols, the CM0DP protocol conversion module can be used, and the MODBUS protocol can be converted to the corresponding field bus. When the LDM9E(CM1) type communicable intelligent molded case circuit breaker is used alone to set the protection parameters of the circuit breaker, a professional person needs to use the FI handheld programmer to connect as shown in the figure below, and then press Operate with the operating instructions of the programmer.
