Schneider 140DRA84000 Central control module

Detailed Product Description

A molded case circuit breaker (MCCB) from Schneider Electric is an electrical device designed to protect electrical circuits from overcurrent conditions such as overloads and short circuits. These breakers are

 commonly used in industrial, commercial, and residential applications. Schneider offers a wide range of MCCBs with varying current ratings, voltage ratings, and trip characteristics to suit different needs.

Key Features and Benefits

• Thermal-magnetic trip: Provides both short-circuit and overload protection.

• Wide range of current ratings: Available in various ampere ratings to accommodate different circuit loads.

• Various trip curves: Offers different trip characteristics (e.g., Type B, C, D) to match specific application requirements.

• Compact and durable design: Ensures long-lasting performance in demanding environments.

• Modular construction: Allows for easy installation and maintenance.

• Additional features: May include ground fault protection, shunt trip, and undervoltage trip.

Technical Specifications

• Current ratings: Typically range from a few amperes to several thousand amperes.

• Voltage ratings: Available for various voltage levels, including low voltage and medium voltage applications.

• Interrupting capacity: The maximum fault current that the breaker can safely interrupt.

• Trip curves: Available in different types (B, C, D) to match the characteristics of the load.

• Mounting options: Various mounting styles are available to suit different installation requirements.

Application

Schneider MCCBs are used in a wide range of applications, including:

• Industrial: Motor control centers, distribution panels, and machine automation.

• Commercial: Building automation systems, lighting circuits, and power distribution.

• Residential: Main service panels, branch circuit protection, and appliance circuits.

Selection Criteria

When selecting a Schneider MCCB, consider the following factors:

• Circuit current: Determine the maximum continuous current that the circuit will draw.

• Fault current: Estimate the maximum fault current that the breaker may be exposed to.

• Voltage rating: Ensure the breaker is rated for the system voltage.

• Trip curve: Choose a trip curve that matches the load characteristics.

• Additional features: Consider any required features such as ground fault protection or shunt trip.

Important Considerations

• Installation: Ensure proper installation according to the manufacturer's instructions and applicable electrical codes.

• Maintenance: Regular inspection and maintenance are essential to ensure the breaker's continued operation.

• Replacement: Replace the breaker with a unit of the same rating and type.

• Safety: Always follow safety precautions when working on electrical equipment.
