Scope of Application

start. Circuit breaker with overload long delay inverse time, short circuit short delay inverse time, short circuit short delay fixed time short circuit

instantaneous and undervoltage protection function and residual current protection (optional), lack of phase protection function (optional), can

protect the line and power equipment from damage, circuit breaker protection features are complete, accurate, can improve the reliability of power

supply, avoid unnecessary power outage, Among them, the "Z, B" type control has a communication interface, which can be "four remote" to meet

the requirements of the control center and automation system.

According to its rated limit short-circuit breaking capacity, the circuit breaker is divided into M-type (higher breaking type) and H-type (high breaking

type). The circuit breaker has the characteristics of small volume, high breaking capacity, short fly-arc and anti-vibration.

The circuit breaker can be installed vertically (that is, vertically) or horizontally (that is, installed).

The circuit breaker has an isolation function, and its corresponding symbol is:

The circuit breaker cannot be inverted into the line, that is, only 1, 3, 5 are allowed to connect the power line, 2, 4, 6 to the load line

Application Scenarios

◎Handheld programmer

LCD display, simple operation, simple interface, can set various protection parameters of the circuit breaker, the last fault query, function editing, Do

function output programming, etc., can be set according to the user's customized program or other functions upgrade.

◎Overload hot memory function

The overload thermal memory function of the controller can be selected by the user, and is off by default when leaving the factory.

The controller overload thermal memory energy is completely released within 30 minutes.

◎Short-circuit thermal memory function

Controller (short delay) Short circuit current protection thermal memory function can be selected by the user, factory default is off.

The controller (short delay) short circuit current protects the thermal memory energy from being fully released within 15 minutes.

◎Fault recording function

The controller can record the fault type, fault trip time, fault phase and maximum fault current of the last 10 times, and no loss of power failure.

◎Fire division function

For the fire protection system, when the tripping condition is reached under the set parameters, the circuit breaker does not trip and outputs the

normally open and normally closed contact, and provides shunt function can be selected by the user whether to disconnect the circuit breaker.

◎Programmable D0 output function

Controller has four photoelectric signal output, D01 and D02 electrical signals can be programmed for the following function output, D03 is a switch

ing signal, D04 is a closing signal.

Long delay fault	Short delay fault	Ground fault
Leakage fault	Instantaneous fault	Overvoltage fault
Overtemperature fault	Cicuit breaker triped due to a fault	Undervoltage tripping
Long delay fault alam	Short delay fault alam	Ground fault alarm
Leakage fault alam	Instantaneous fault alam	Overvoltage fault alam
Overtemperature fault alam	Trip alarm due to fault	Undervoltage fault alarm

◎Circuit breaker on/Off state detection function (Optional function)

The controller can detect the current on/off state of the circuit breaker and transmit it to the host computer to the computer network in real time.

Normal working conditions

Note:

◎Altitude: ≤2000m

◎Ambient temperature: -5℃~+40℃

◎Resistant to humid air

◎It is resistant to salt spray and oil spray

◎The installation category of the main circuit of the breaker is Ⅲ, and the installation category of the other auxiliary circuits and control circuits is Ⅱ.

◎When the maximum temperature is +40 ° C, the relative humidity of the air does not exceed 50%, and a higher relative humidity can be allowed at a lower humidity,special measures should be taken for condensation occasionally caused by temperature changes.

◎The maximum inclination is 22.5°

◎In a medium where there is no danger of explosion, and where the medium is free of gases and conductive dust sufficient to corrode metal and destroy insulation

◎Where there is no rain or snow

Structural features

The ZYM1E Series Electronic Molded Case Circuit Breaker adopts advanced electronic trip technology to provide precise and reliable protection for modern low-voltage power distribution systems. Compared with conventional thermal-magnetic circuit breakers, it offers more accurate protection characteristics, flexible parameter settings and intelligent monitoring capabilities.

The breaker integrates overload long-time delay protection, short-time delay short-circuit protection, instantaneous short-circuit protection and undervoltage protection into a compact structure. Optional residual current protection and phase-loss protection functions are available to meet various application requirements.

A high-performance electronic trip unit continuously monitors circuit conditions and accurately detects abnormal current fluctuations, ensuring fast fault response while reducing unnecessary tripping and power interruptions.

The optimized contact system and arc-extinguishing chamber provide excellent breaking performance and reliable operation under high fault current conditions. The breaker features short arcing distance, strong anti-vibration capability and long service life.

For intelligent power distribution applications, communication and remote-control functions are available. The intelligent communication version supports integration with automation systems, enabling remote monitoring, fault diagnosis and centralized management.
