Circuit breakers (CBs) are devices designed to protect electrical systems and components from damage due to overcurrent, short-circuits, or fault current. The R21-2-9.00A-33168-2-V is a type of circuit breaker specifically designed for use in low-voltage systems. While circuit breakers can vary in size and configuration, the R21-2-9.00A-33168-2-V is a relatively small and straightforward device.

Purpose and Design

The R21-2-9.00A-33168-2-V circuit breaker is designed for use in low-voltage outdoor lighting systems, such as walkway, parking lot, and driveway lights. It is a cost-effective device that provides reliable overcurrent protection while also allowing lights to be cycled on and off. The breaker has a pre-set 9.00A current rating and a short-cycle protection feature. This feature helps prevent the lights from being switched on and off too quickly, which can cause damage to the system.

Installation

Installing the R21-2-9.00A-33168-2-V is a relatively straightforward process. The circuit breaker is designed to be mounted directlty to a vertical pole or structure, so it can be easily incorporated into existing systems. Once the breaker has been mounted, all that is required is to connect it to the lighting system using wires. The breaker should then be wired in such a way that the live wires, coming from the power source, are connected to the “line” posts and the outgoing power supply, to the lighting system, is connected to the “load” posts.

Operation

The R21-2-9.00A-33168-2-V is designed to operate with minimal user intervention. It is automatically triggered when the current exceeds the 9.00A pre-set rating. When this occurs, the breaker trips off, shutting down the electrical power supply to the lighting system. The breaker can then be manually reset, allowing the lights to be switched on again.

Benefits

One of the main benefits of using the R21-2-9.00A-33168-2-V circuit breaker is that it provides reliable protection against overcurrent, short-circuits, and fault current. This ensures that the lighting system will not be damaged if any of these events occur. Additionally, the breaker’s short-cycle protection feature helps prevent damage to the system from too frequent switching on and off of the lights.

The R21-2-9.00A-33168-2-V is an effective and cost-efficient device for providing reliable overcurrent protection in low-voltage lighting systems. With minimal user intervention and a pre-set 9.00A current rating, it is a reliable solution for many applications.
