About Hyundai Air Circuit Breaker

Air Circuit Breaker or ACB is a specially designed electronic device that can function in air in the form of an arc extinguishing medium at a set atmospheric pressure. These circuit breakers that can deliver overcurrent & short-circuit protection mostly find use in low voltage applications (below 450V). Our Air Circuit Breaker based on sophisticated technology are easy to install and deliver reliable performance as compared to the oil circuit breakers. These ACBs we offer come with adjustable trip characteristics.

Comprehensive Protection and Versatile Operations

Hyundai Air Circuit Breakers offer superior circuit protection with built-in thermal safeguards and a full range of protection curves. Their versatility accommodates both fixed and draw-out installations, vertical or horizontal mounting, and the option for auxiliary contacts. Integrated indicators and interlock systems ensure operators have all the information and safety mechanisms needed for reliable operation in diverse applications.

Adaptability and Reliability in Performance

Rated for operation in extreme environments, these breakers maintain functionality from -5C to +55C, withstood ambient storage from -40C to +70C. Highly resilient, they function across 50/60Hz frequencies with 5% tolerance and come with protection degrees from IP30 (standard) up to IP54 with the enclosure. A mechanical life of up to 10,000 operations guarantees longevity and dependable performance.

FAQs of Hyundai Air Circuit Breaker:

Q: How does the Hyundai Air Circuit Breaker provide circuit protection?

A: The breaker uses microprocessor-based or electronic trip units to detect and interrupt overcurrents, faults, and temperature anomalies. Multiple protection curves (L, S, G, I) and built-in thermal protection help safeguard electrical circuits against overloads and short circuits.

Q: What are the installation and mounting options for this circuit breaker?

A: This breaker supports both fixed and draw-out installations. It can be mounted vertically or horizontally, making it adaptable for various panel configurations in industrial and commercial setups.

Q: When should I choose the auxiliary contact option?

A: Auxiliary contacts are recommended whenever you need to signal external devices or systems (such as alarms or remote monitoring) about the operational status of the circuit breaker. This is particularly beneficial for automation and enhanced safety monitoring.

Q: Where can this air circuit breaker be used effectively?

A: It is suitable for use in power distribution panels in commercial, industrial facilities, and utility substations. Its robust performance across wide temperature ranges and high breaking capacities allow for installation in demanding electrical environments.

Q: What is the process for maintenance or inspection of this circuit breaker?

A: Routine maintenance involves visual inspection, operation checks using manual or motorized controls, cleaning, and testing of trip unit functions and indicators. The draw-out design permits easier access and safer handling during service.

Q: How does the breakers interlocking system enhance safety?

A: Mechanical and electrical interlock systems prevent simultaneous closing of connected breakers and unauthorized access during maintenance, ensuring operator safety and system integrity.

Q: What benefits do users gain from the breakers temperature and thermal protection?

A: Users benefit from reliable operation and extended equipment lifespan, as the built-in protections prevent overheating, reduce the risk of damage to electrical systems, and minimize unscheduled downtime due to thermal-related faults.
