Series Overview
Outstanding Product Features
Miniaturization and Digital Twin Capability
● Feature-rich, compact size, installation dimensions identical to CM3 and CM3E, facilitating complete set usage.
Reliable Operation and Excellent Performance
● Ultimate short-circuit breaking capacity (Icu) up to 85kA / 100kA, operational life reaching 20,000 cycles, ensuring high reliability.
● Rated impulse withstand voltage up to 8kV, equipped with isolation function and correct indication, ensuring high safety performance.
Multifunctional, Meeting Intelligent Management Needs
● Integrates overload, short-circuit, undervoltage, overvoltage, phase failure, neutral failure, residual current (earth leakage) protection, etc.
● Capable of mounting various accessories to provide auxiliary, alarm, undervoltage, shunt trip signals and other switching information required for control.
Smart Communication
● Built-in RS485 communication interface, featuring telemetry, tele-signaling, tele-control, and tele-adjusting functions, enabling intelligent grid management.
User-Friendly Design
● Utilizes a large LCD display, automatically cycling to show real-time residual current value and residual current operating value.
● Automatically displays trip cause, fault phase sequence, and parameters at trip upon fault tripping.
● Clear interface allows users to conveniently control the circuit breaker and set parameters directly on the panel.
Application Scenarios
Low-Voltage Distribution Protection
● OM3Z and OM3ZL circuit breakers can be used in AC 50/60Hz TN, TT, IT distribution systems, meeting the requirements for "Selection of Electrical Appliances" in GB50054-2011.
● OM3Z and OM3ZL circuit breakers provide reliable contact indication and isolation functions, satisfying the GB50054 requirements for isolation devices.
Motor Circuit Protection
● CM3Z and CM3ZL circuit breakers provide overcurrent protection for motor starters, cables, and motors. Their protection characteristics comply with GB/T 14048.4, and their application meets GB50055.
Residual Current Protection
● CM3ZL circuit breakers provide protection against dangerous contact voltages caused by insulation faults, and also protect against hazards like fires arising from insulation damage, such as cable insulation failure.
● CM3ZL circuit breakers with a rated residual operating current of 30mA can provide additional protection against direct contact.
● CM3ZL circuit breakers provide Type A residual current protection for AC superimposed pulsating DC conditions, meeting the selection requirements for residual current protective devices in GB50054 and GB13955.
● Operating time meets the grading coordination requirements of GB13955.
Product Series Overview
● OM3Z Molded Case Circuit Breakers (MCCBs, hereinafter referred to as circuit breakers) are intelligent products launched by our company as part of the OM3 series. The circuit breakers come in five frame sizes: 100A, 250A, 400A, 630A, and 800A, with current ratings from 12.5A to 800A. CM3ZL integrates residual current protection functionality based on the CM3Z circuit breaker, available in four frame sizes: 100A, 250A, 400A, and 800A, with current ratings from 40A to 800A and residual currents from 30mA to 1000mA.
● Based on the level of rated ultimate short-circuit breaking capacity (Icu), the circuit breakers are classified into two levels: Type I (Higher Breaking Capacity) and Type H (High Breaking Capacity).
● The circuit breakers can be installed horizontally (sideways), vertically (upright), or flat.
● All circuit breakers have an isolation function, indicated by the symbol: ●
● CM3ZL circuit breakers can feature earth leakage alarm without tripping to avoid significant losses caused by power outages, meeting the requirements of Clause 4.6 in GB13955-2005.
● The circuit breakers comply with the following standards:
● IEC 60947-1 & GB/T 14048.1-2012 Low-voltage switchgear and controlgear - General rules
● IEC 60947-2 & GB/T 14048.2-2008 Low-voltage switchgear and controlgear - Circuit-breakers
● IEC 60947-4-1 & GB/T 14048.4-2010 Low-voltage switchgear and controlgear - Contactors and motor-starters - Electromechanical contactors and motor-starters (including motor protection devices)
