Fuji SA32 Auto Breaker 2 Pole 3A Circuit AC600V

The Fuji SA32 Auto Breaker is a 2-pole, 3A circuit breaker designed for use in alternating current (AC) systems with a maximum voltage rating of 600V. It is typically used in electrical panels and distribution boards to protect electrical circuits from overloads and short circuits.

Here are some key specifications and features of the Fuji SA32 Auto Breaker:

Key Specifications:

• Model: SA32
• Type: Automatic Circuit Breaker (also known as a Molded Case Circuit Breaker, MCCB)
• Number of Poles: 2
• Current Rating: 3A
• Voltage Rating: 600V AC
• Frame Size: Suitable for medium- to large-scale applications (typically in industrial or commercial settings)
• Interrupting Capacity (IC): Typically, this type of breaker is rated for high interrupting capacity, meaning it can safely disconnect a circuit during a fault condition (e.g., short circuit).
• Operating Temperature Range: Often around -5°C to +40°C, but specific models may vary.
• Frequency: Typically 50/60 Hz
• Mounting Type: Usually DIN rail or screw-mounted depending on the design and model.

Features:

1. Overload Protection: The circuit breaker can protect against overloads by tripping when the current exceeds the rated value (in this case, 3A).
2. Short Circuit Protection: It automatically disconnects the circuit when a short circuit is detected, preventing further damage to equipment or wiring.
3. Manual Reset: After tripping, the breaker needs to be manually reset to restore power.
4. Compact Design: Despite its robust construction, the Fuji SA32 is designed to be compact and easy to install in panelboards or switchgear.
5. High Interrupting Capacity: Designed to interrupt large fault currents, ensuring safe disconnection during extreme fault conditions.
6. Bimetallic Overload Trip: Many breakers like the SA32 use bimetallic elements to provide thermal overload protection, which trips when sustained overcurrent occurs.

Applications:

• Residential & Commercial Electrical Distribution Panels: To protect circuits in residential, commercial, and light industrial electrical systems.
• Motor Protection: Often used to protect motors and related equipment from overloads and short circuits.
• Industrial Equipment: Protects electrical equipment from damaging electrical faults, especially in factory or plant environments.
• AC Power Systems: Suitable for use in AC power distribution systems, including control panels and subpanels.

Advantages:

• Reliability: Fuji Electric is known for durable, reliable circuit breakers that provide peace of mind in protecting critical electrical infrastructure.
• Space-Efficient: Offers a compact design for space-conscious applications.
• Adjustable Protection Settings: In some versions, the protection characteristics (such as trip curve) can be adjusted to suit specific needs.

Important Notes:

• Installation and Wiring: Proper installation is critical for ensuring the breaker functions correctly. This may include ensuring the correct wire gauge is used and connections are properly tightened.
• Maintenance: Like all circuit breakers, it’s important to periodically check the breaker for signs of wear or malfunction, such as signs of overheating or faulty trips.
• Compliance: Ensure the breaker is suitable for your application’s voltage, current, and regulatory requirements. Always refer to the manufacturer’s guidelines for exact specifications and safety standards.
