Key Features of WLM6-400A-3300 [https://www.w9-group.com/wlm6-400a-3300-3p-4p-wlm6-series-400vac-thermal-magnetic-type-moulded-case-circuit-breaker-400v-690v-400a-3-4-poles-product/]

* Rated Current: 400A
* Number of Poles: 3P / 4P
* Rated Working Voltage: 400V/690V
* Type: Thermal Magnetic
* Series: WLM6 Series

Technical Specifications

* Rated Current (In): 400A
* Number of Poles: Available in 3P (three poles) and 4P (four poles) configurations.
* Rated Working Voltage: 400V/690V, suitable for a wide range of applications.
* Breaking Capacity: High breaking capacity ensures safe interruption of high fault currents.
* Thermal Operation: Protects against prolonged overcurrent conditions by utilizing a bimetallic strip that bends and trips the breaker.
* Magnetic Operation: Provides instant protection against short circuits using an electromagnetic mechanism.

Functionality

The WLM6-400A-3300 MCCB (Moulded Case Circuit Breaker) is designed to provide comprehensive protection to electrical circuits. Its functionality is built on two primary protective mechanisms: thermal and magnetic. Here's how each function operates:

Thermal Protection

* Operation: The Thermal MCCBbprotection feature uses a bimetallic strip that responds to sustained overcurrent conditions. When the current flowing through the MCCB exceeds its rated value (400A) for an extended period, the bimetallic strip heats up and bends.
* Mechanism: The bending of the strip triggers the trip mechanism, disconnecting the circuit. This prevents overheating and potential damage to the electrical components due to prolonged overcurrent.
* Application: This is particularly useful in preventing overheating in scenarios where a gradual increase in current occurs, such as in overloaded circuits.

Magnetic Protection

* Operation: The magnetic protection feature uses an electromagnetic coil to respond to instantaneous overcurrent, such as short circuits. When a short circuit occurs, the high current generates a strong magnetic field in the coil.
* Mechanism: The magnetic field rapidly moves a plunger or lever that triggers the trip mechanism, disconnecting the circuit almost instantly.
* Application: This rapid response is crucial in protecting electrical systems from the severe damage that can result from short circuits, which can cause fires and equipment failure.

Applications

The WLM6-400A-3300 MCCB is versatile and suitable for a wide range of applications across various industries. Here are some common scenarios where this MCCB can be effectively utilized:

Industrial Applications

* Manufacturing Plants: In industrial settings where large machinery and equipment operate, the MCCB provides essential protection against overcurrent and short circuits, ensuring the safety of both equipment and personnel.
* Power Distribution: It is used in power distribution systems to safeguard electrical panels and subpanels from faults that could disrupt operations and damage infrastructure.

Commercial Applications

* Building Management Systems: In commercial buildings, the MCCB protects electrical systems in offices, shopping centers, and other facilities, ensuring uninterrupted power supply and safety.
* HVAC Systems: The MCCB is crucial for protecting heating, ventilation, and air conditioning (HVAC) systems from electrical faults that could lead to system failure and costly repairs.

Residential Applications

* Main Electrical Panels: In residential settings, the MCCB is used in main electrical panels to protect household circuits from overcurrent and short circuits, providing safety and preventing potential fire hazards.
* High-Power Appliances: It is also used to safeguard high-power appliances, such as electric stoves and water heaters, from electrical faults.

Renewable Energy Systems

* Solar Power Systems: The MCCB is used in solar power installations to protect the circuits that connect solar panels to inverters and batteries, ensuring safe and reliable operation.
* Wind Turbines: In wind energy systems, it protects electrical components from faults caused by fluctuating power generation and other issues.

Thermal Protection

The thermal protection feature operates using a bimetallic strip that responds to prolonged overcurrent. When the current exceeds the rated value for a specific duration, the bimetallic strip heats up, bends, and trips the breaker. This prevents overheating and potential damage to the electrical system.

Magnetic Protection

The magnetic protection feature is designed to respond instantaneously to short-circuit conditions. An electromagnetic coil generates a magnetic field that triggers the tripping mechanism, ensuring rapid disconnection of the circuit. This helps to prevent severe damage and potential fire hazards caused by high fault currents.

Design and Construction

* Compact Design: The WLM6-400A-3300 MCCB features a compact and robust design, making it suitable for installation in various environments.
* High Durability: Constructed with high-quality materials, this MCCB offers excellent mechanical and electrical endurance.
* Ease of Installation: Designed for easy installation and maintenance, it includes clear labeling and accessible terminals.

Compliance and Certifications

The WLM6-400A-3300 MCCB complies with international standards such as IEC, ensuring that it meets stringent safety and performance requirements. It also holds various certifications that attest to its quality and reliability.
