ZGLEDUN LDM9E Small Size Electronic Intelligent MCCB Molded Case Circuit Breaker, Manufacturer Smart MCCB with communication functions

Product Description:

ZGLEDUN Series LDM9E electronic smart molded case circuit breaker is suitable to be used in low-voltage electric circuits of AC 50Hz/60Hz, rated voltage up tp 1000V and the rated working current 16A- 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.

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).
This MCCB can be customized to suit your needs.

Product Features:

This intelligent molded case circuit breaker can be equipped with accessories such as undervoltage release, shunt release, auxiliary contact, alarm contact, electric operating mechanism, and rotating operating handle.

The circuit breaker has protection functions such as overload long time delay, short circuit short time delay, short circuit instantaneous, etc. The user can set the required protection characteristics as long as the protection function parameters are set with a code switch. The MCCB circuit breaker has a ground fault, thermal analog protection function, pre-alarm indication, over-current indication, overload indication function and digital current analysis technology, so it can achieve a higher level of protection. The LDM9E series is a range of circuit breakers with residual current protection function.

Installation & Working Conditions:

Altitude: ≤2000m;
Ambient temperature: -51℃ ~+ 40℃ ( +45℃ for marine products)
This MCCB can withstand the influence of humid air, salt mist, oil mist, mucedine and radiation.
The MCCB can still work reliably under normal ship vibration.
Under earthquake conditions (4g), the MCCB can still work reliably.
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.
