Wroking Principle of Intelligent Universal Circuit Breaker

Real-time fault detection：BYCW1 is equipped with highly sensitive current sensors that continuously monitor the circuit breaker (MCB) current and three-phase power supply voltage levels. When the overload and short-circuit protection thresholds are breached (such as excessive current or voltage spikes), the embedded microprocessor immediately triggers the action. Universal circuit breaker lockout and universal circuit breaker lockout/lockout prevent unauthorized adjustments in fault conditions, thereby enhancing the safety of the circuit.

Thermal overload protection: The bimetallic strips inside the circuit breaker expand and bend under prolonged overload, mechanically opening the contacts. This prevents the three-phase installation of the power line from gradually overheating.

Magnetic short circuit protection: When a sudden short circuit occurs, the solenoid-driven armature quickly breaks the circuit, achieving near-instantaneous disconnection. This mechanism minimizes damage to power quality equipment and downstream MCB circuit breaker units.

Intelligent control and coordination:BYCW1's power protection circuit uses a digital control unit to analyze real-time data from power system equipment. It dynamically adjusts trip settings to optimize energy utilization while maintaining compatibility with the main power breaker panel. For example, during voltage fluctuations, the circuit breaker prioritizes stabilizing power supply to critical loads, thereby minimizing downtime.

Air arc extinguishing technology:As an air circuit breaker (ACB), BYCW1 uses pressurized air to extinguish the arc generated during the tripping process. The arc is guided into a specially designed flow channel, where it safely extends and dissipates, preventing damage to internal components. This design ensures reliable operation in high-current industrial environments.

Drawer and fixed flexibility:Both configurations are easy to install and maintain. The drawer type allows for quick replacement without disconnecting the entire power distribution system, while the fixed type provides strong stability for permanent installation. Both models support remote monitoring through an integrated communication module, meeting the needs of modern power quality management.

Key Functions of Intelligent Universal Circuit Breaker

1. Intelligent overload and short circuit protection
The BYCW1 series integrates advanced thermal-magnetic releases and electronic sensors to provide overload and short-circuit protection within milliseconds. Its adaptive algorithm detects abnormal currents and triggers instantaneous tripping to prevent equipment damage. Its short-circuit current protection up to 100kA prevents catastrophic failures in three-phase power systems and is ideal for industrial facilities and power grids. The simple overcurrent protection circuit ensures precise response to sustained overloads, minimizing downtime and maintenance costs.

2. Universal safety locking mechanism
The air circuit breaker (ACB) is equipped with a universal miniature circuit breaker (MCB) lockout and a universal circuit breaker lockout to prevent unauthorized operation and ensure compliance with safety standards. The tool-free durable nylon design allows for quick installation on miniature circuit breakers (MCBs) and molded case circuit breakers (MCCBs) and is equipped with a two-way padlock slot for enhanced security. These mechanisms are critical in high-risk environments, such as manufacturing plants, where accidental energization can lead to serious accidents.

3. Three-phase voltage regulation and compatibility
BYCW1 three-phase circuit breaker can effectively manage three-phase voltage fluctuations and solve harmonic distortion and phase imbalance problems. It supports both drawer-type and fixed-type configurations, suitable for various power distribution systems in commercial buildings and industrial parks. The molded case circuit breaker (MCCB) design ensures seamless integration with existing power infrastructure, and its 380V rated voltage is also suitable for applications that require high voltage stability.

4. Intelligent monitoring and energy optimization
BYCW1 has a built-in communication module that can monitor energy usage and power quality in real time through the IoT platform. Its self-diagnosis function can alert users to potential faults, thereby reducing maintenance work. By optimizing the three-phase efficiency of the power line, this circuit breaker can reduce energy waste and extend the life of equipment. The simple overvoltage protection circuit can reduce the risk of voltage spikes and ensure the stable operation of sensitive electrical equipment.

5. Vacuum circuit breaker technology
BYCW1 uses vacuum circuit breaker technology, which has superior arc extinguishing ability and longer service life than traditional air circuit breakers. Its compact design supports high interrupting capacity up to 150kA, which is very suitable for critical applications such as data centers and renewable energy systems. The component design of the circuit breaker ensures that parts are easy to replace, thereby improving the reliability of the overall system.

6. Industry-leading power quality solutions
Manufactured by Baoyu Holding Co., Ltd., a trusted power quality equipment manufacturer, BYCW1 integrates seamlessly with harmonic control and reactive power compensation systems. It acts as a main power circuit breaker in the distribution network, ensuring compliance with international standards (IEC/UL) while improving grid stability.

Wiring Method of Intelligent Universal Circuit Breaker

1. The controller's signal output drives the external relay u through terminals 12-18, 20, and 21 to provide output contact action signals.

2.RS485/232 converter, DP module and current transformer (input voltage value must be specified) are provided by the manufacturer. The power transformer can be inserted into the standard rail together with the relay base, and the user is responsible for installing it in the appropriate position in the switch cabinet.

3. The relay model is HH62P, AC/DC 24V, and is prepared by the user.

4.The main station computer is provided by the user.

5.Terminals 13-15 output communication remote tripping, closing, and energy storage signals. At this time, terminals 14 and 15 no longer output tripping signals. The normally open contacts of the corresponding relays are connected in parallel with the active control buttons to achieve remote control. If remote control is not required, terminals 14 and 15 can be connected in series with the normally open contacts of relays J14 and J15 to form two remote signal outputs. Please indicate whether the remote control function is required when ordering. The manufacturer will determine the corresponding functions of terminals 14 and 15 accordingly. Terminal 21 output can drive relay J21 to achieve backup protection.

6.The self-diagnosis signal output is as follows:

• The internal temperature of the controller is >80°C;
• The chip is not working properly;
• The controller is powered off.
