Circuit breakers are a common safety feature in residential and industrial applications, providing protection against electrical load surges. The UPG666-4094-1 is a type of circuit breaker used in industrial settings. It provides protection against short-circuits, overloads, and overvoltages, ensuring safety and preventing damage to the electrical system.

The UPG666-4094-1 is a three-pole, non-interchangeable trip molded case circuit breaker. It utilizes a trip unit that is highly reliable and is constructed of a durable plastic material. The trip switch is adjustable, allowing the user to select the appropriate ampere rating. Additionally, the unit is UL-listed for emergency stop, short-circuit protection, and overload protection.

The main component of the UPG666-4094-1 is the trip mechanism, which is responsible for detecting faults and switching off the circuit before a hazardous condition can be created. The trip unit consists of two parts: thermal-magnetic and electronic. The thermal-magnetic element is designed to sense temperature increases due to overcurrents and switch off the circuit to avoid an overload or short circuit. This type of element is also known as a bimetallic strip. The electronic element is designed to detect an excessive rate of change in currents, protecting the circuit from transients and sudden surges.

In general, the UPG666-4094-1 circuit breakers can be used for most applications that require overload and short circuit protection. They can be used in residential and light commercial settings, as well as in industrial and hazardous locations. These breakers are suitable for use in both indoor and outdoor applications, depending on the environmental conditions.
