Circuit breakers are a crucial component of any electrical system for protecting it from damage due to overloading or short-circuiting. The model of circuit breaker discussed in this article is the UPGH111-3REC2-2919-33. This circuit breaker is a three-pole configuration designed for use in industrial control and power distribution applications. It is a type 2 combination circuit breaker with a rated current of 105 A.

The working principle of the UPGH111-3REC2-2919-33 is based on the magnetic principle, where the incoming current is monitored and the bimetal or trip coil is heated if more current is detected than the rated value. When the bimetal or trip coil reaches a temperature above the rated value, the circuit breaker trips, and the circuit is disconnected. This immediately protects the electrical system from overload or short-circuit damage.

A key feature of the UPGH111-3REC2-2919-33 is its trip-free mechanism. This feature ensures that the circuit remains disconnected, even if an unintentional on-command is issued. This mechanism is a standard requirement for safety applications, as it prevents an overload or short-circuit from occurring if the circuit breaker is in the off position.

Additionally, the UPGH111-3REC2-2919-33 has a manual override feature, which enables the user to manually reset the circuit breaker when necessary. This feature can be used effectively when troubleshooting or performing maintenance on an electrical system. It is also worth noting that this circuit breaker has a signal contact for alarms and trip indication, to detect any over-current and trip the circuit breaker before any damage can occur.

The UPGH111-3REC2-2919-33 is ideally suited for applications in industrial control and power distribution systems. It is designed to provide reliable circuit protection in harsh and hazardous environments, and is certified according to IEC 60947-2 and UL 489 standards. It is also suitable for use in a wide range of medium voltage applications, such as motor control centers, automated systems, and MCCs. It has a low current rating, making it suitable for use in low voltage power distribution applications.

The UPGH111-3REC2-2919-33 is an ideal circuit breaker for industrial control and power distribution applications. It is a combination type 2 circuit breaker with a rated current of 105 A, and its trip-free mechanism and manual override feature ensure reliable circuit protection. Additionally, it has a signal contact for alarms and trip indication, and is certified according to the applicable standards. This makes it suitable for a wide range of medium voltage applications.
