Essential Air Circuit Breaker (ACB) Spares and Accessories

Air Circuit Breakers (ACBs) are crucial components in protecting electrical circuits by disconnecting high currents and managing low voltage situations. They play a vital role as the primary circuit breaker in ships, buildings, and factories. To ensure optimal performance and reliability, it’s important to have access to a variety of ACB spares and accessories.

Key ACB Spares and Accessories

1. Alarm Contacts
   • Designed to alert users to circuit breaker incidents, including short circuits, overloads, and undervoltage situations.
2. Excitation Tripper
   • A voltage-driven device that facilitates long-distance switch-off operations, enhancing safety and control.
3. Undervoltage Tripper
   • Automatically opens the circuit breaker when the terminal voltage drops below a specific threshold, protecting equipment from damage.
4. Electric Operator
   • An accessory that enables remote switching and closing of circuit breakers, improving operational convenience.
5. Extended Handle
   • An external handle attached to the circuit breaker’s handle for easy manual switching.
6. Handle Locking Device
   • A clamp that can be locked with a padlock, providing an added layer of safety by preventing unauthorized operation.

Additional ACB Components

In addition to the primary spares and accessories, ACBs consist of various other essential parts, including:

• Front Cover: Protects internal components and provides access for maintenance.
• Electronic Trip Relay: Monitors current levels and triggers the trip mechanism when necessary.
• Auxiliary Switch: Provides additional functionality, often used for signaling or control purposes.
• Arc Extinguishing Chamber: Designed to safely dissipate the energy of an electric arc during a trip.
• Closing Coil: Engages to close the circuit breaker, ensuring a secure electrical connection.
• ON/OFF Indicator: Clearly displays the operational status of the circuit breaker.
• Closing Mechanism: Facilitates the actuation of the circuit breaker to ensure reliable operation.
• Trip Mechanism: Triggers the breaker to open during fault conditions, protecting the circuit.
