Circuit Breakers are an important component of an electrical system. The UPG266-6821-3 is a powerful and reliable circuit breaker that is widely used in a variety of applications. It is designed to protect against overloads, short circuits, and ground faults, and is ideal for applications that require high ampere ratings. This circuit breaker also offers several features that make it the preferred choice for a variety of tasks.

The UPG266-6821-3 is a three-pole, three-phase circuit breaker. It is designed to provide high current and arc fault protection for three-phase systems. It is rated for use with up to 3000 amperes, depending on the application. Its compact size and low profile make it ideal for applications where space is limited. Additionally, the UPG266-6821-3 can be interlocked to operate as a dual-pole/dual-throw switch. This allows the user to switch from one function to the other without a mechanical operator.

The UPG266-6821-3 operates with a thermal-magnetic trip system. This means that internal sensors detect when the current is too high and energize an electromagnet that pulls a plunger used to trip the breaker. When the current exceeds a preset threshold, the plunger trips the breaker and the circuit is opened. The spring-loaded mechanism allows for quick reset and ensures that the circuit is automatically reconnected when the current has dropped to a safe level.

The unique design of the UPG266-6821-3 allows for easy installation and operation. Its low profile and lightweight design makes it easy to install in almost any application. The internal sensor system ensures that the breaker remains operational even in environments where excessive moisture or dust is present. Additionally, the UPG266-6821-3 is designed to be compatible with almost any wiring configuration. This ensures that it can be used in a variety of applications.

In addition to providing overload, short circuit, and ground fault protection, the UPG266-6821-3 also includes an impressive selection of safety features. The breaker is designed to be UL 489 listed, which means it meets the highest standards of safety when used in residential and commercial applications. Additionally, this breaker is designed to be installed in junction boxes that are compliant with the National Electrical Code. This ensures that the breaker is able to resist fire, mechanical, and electrical hazards when installed properly.

The UPG266-6821-3 is a powerful and reliable circuit breaker that can meet the needs of any application. Its high ampere ratings, low profile, and ease of installation make it an ideal choice for residential, commercial, and industrial applications. Additionally, the safety features and UL 489 listing ensure that the breaker is able to resist fire, mechanical, and electrical hazards when installed correctly.
