Circuit Breaker Remote Racking Systems

Circuit Breaker Remote Racking Systems are specialized devices designed to safely operate circuit breakers from a distance, typically outside the arc-flash hazard boundary. These systems allow operators to remotely insert or withdraw (rack in or rack out) circuit breakers into their switchgear cubicles, reducing the risk of electrical arc flash accidents and exposure to high-voltage environments.

Key Components and Features:

1. Remote Operation: The system is controlled from a safe distance, usually through a handheld control unit or a fixed control panel, allowing operators to avoid direct contact with potentially dangerous equipment.
2. Motorized Mechanism: The system uses an electric motor to engage with the breaker’s racking mechanism, which typically requires manual turning. This motorized operation replaces the manual effort, reducing operator fatigue and human error.
3. Safety: The primary purpose of these systems is safety. They protect workers from electrical hazards, especially arc flashes, by maintaining a distance between the worker and the high-energy components. Arc flash incidents can occur when circuit breakers are being inserted or removed under load, and this system mitigates that risk.
4. Compatibility: Most remote racking systems are designed to be compatible with a variety of low- and medium-voltage circuit breakers from different manufacturers. Some systems can also be adjusted or customized for specific breaker types.
5. Torque Control: Many remote racking systems have torque monitoring to ensure that the circuit breaker is racked in or out with the correct force. This feature helps prevent equipment damage caused by applying too much or too little force during the racking process.
6. Portability: Many systems are designed to be portable so they can be used across different breaker cubicles within a facility. Some models are compact and easy to transport.

Benefits:

• Improved Safety: The primary benefit is the reduced risk of arc flash accidents and electric shocks.
• Efficiency: Remote racking systems save time by automating the racking process, especially for large circuit breakers.
• Ergonomics: The system eliminates the physical strain of manually operating heavy circuit breakers.
• Compliance: Helps facilities comply with safety standards, such as OSHA and NFPA 70E, which emphasize the reduction of exposure to electrical hazards.

These systems are often used in industrial, commercial, and utility environments where large circuit breakers are frequently operated.  Contact Infinity Technical Services Division for more information at 833-873-4897.
