Description：

Our​‍​‌‍​‍‌​‍​‌‍​‍‌ Electronic Molded Case Circuit Breaker (MCCB) is a step forward in the evolution of intelligent circuit protection, as it digitizes the monitoring process while maintaining the reliable interruption performance. Through a microprocessor-based trip unit, it is possible to program and adjust the trip parameters for overload, short-circuit, and ground-fault situations. A robust and compact thermoset casing is designed to protect a set of high-accuracy electronic components that are capable of continuous current measurement, energy metering, and recording of the fault diagnostic data.

Key Features:

• Protection curves (L, S, I, G) fully adjustable
• Integrated LCD screen for viewing the set parameters and electrical values
• Communication-ready design that supports RS485 and Modbus protocol
• High breaking capacity of up to 100 kA at 415 V
• Broad current range from 100A to 1600A
• It is applicable for both DIN rail and panel-mounted installations

Advanced Capabilities:

• Continuous measurement of current and voltage
• Energy consumption metering and reporting
• Pre-alarm notifications and fault warning messages
• Event logging for troubleshooting and maintenance guidance
• Through the communication interface remote control and monitoring is possible

Primary Applications:

• Smart power distribution networks
