Circuit breakers are an integral part of an electrical system, designed to protect the system from overloads and faults. UPG66-1-61-303-01 is a thermal magnetic circuit breaker specifically designed for larger systems, such as motor drives and high power applications. It is a double-pole circuit breaker, meaning it is capable of breaking both line and load power simultaneously when an overload or fault is detected.

The UPG66-1-61-303-01 circuit breaker features a thermal-magnetic design. This means that it has both an electromechanical thermal element as well as a magnetic field element in its design. The thermal element will trip when the current flow is far enough outside of the normal operating range. The magnetic field element acts as an additional layer of protection, tripping when the current flow of the system rises above a certain level.

The UPG66-1-61-303-01 is designed for higher power applications, up to 110A. It has an adjustable current rating range from 3A to 110A and is capable of handling fault currents up to 6kA. The breaker also has adjustable tripping speed, allowing users to set the time it takes for the circuit breaker to trip in the event of an overload or fault.

The UPG66-1-61-303-01 is a double-pole circuit breaker, meaning it has two separate poles, one for line and one for load. It is designed for use in either single-phase or three-phase systems, and it can be used as either an individual breaker or as part of an electrical control panel. In the event of an overload or fault, both poles trip simultaneously, cutting power from both phases.

The UPG66-1-61-303-01 is designed for larger load applications, such as motor drives, light-industrial equipment, and power control systems. It is UL and CSA approved, and is rated for A.C. and D.C. operation. It is constructed with a thermosetting thermoplastic case and cover, with a zinc-plated steel base for additional corrosion resistance. The breaker is also housed in a molded case suitable for both panel and DIN rail mounting.

The UPG66-1-61-303-01 is designed for reliable operation in higher power applications. Its thermal-magnetic design ensures protection from both overloads and faults, making it an ideal choice for motor drives, light-industrial equipment, power control systems, and other high-powered applications. Its adjustable current rating, high interrupting rating, and wide range of installation options make it a perfect choice for any larger power system.
