Circuit breakers are a very important component of electrical systems. They are designed to protect against short circuits, overloaded circuits, and overheating. UPG11-7136-1 is one such type of circuit breaker, and it is used in various applications.

UPG11-7136-1 is a rating 125A/600VAC 3-pole molded case thermal-magnetic circuit breaker. It is suitable for use in residential, commercial, and industrial applications. The breaker features trip-free operation, single operation reset, and trip signalling.

The UPG11-7136-1 has a simple yet reliable working principle. It operates by interrupting the electrical flow when the current exceeds the rated value. The unit consists of a bimetallic strip that bends when heated due to a high current, overcoming the pressure of two springs and engaging a mechanism that disconnects the contactors.

The unit also includes a thermal-magnetic element, which is a thermal switch with a magnetic component. It senses both current and temperature to detect an overload situation. The magnetic element senses the current, while the thermal element senses the temperature. When the current or temperature reaches a certain level, the thermal-magnetic element opens, triggering the bimetallic strip to bend and activate the contacts.

This mechanism allows the UPG11-7136-1 to protect circuits from short circuits, circuit overloads, and overheating. The unit is also designed to operate quickly and reliably to ensure the safety of the circuit. The trip time of the unit is adjustable, allowing users to customize the unit to the specific situation.

The UPG11-7136-1 is a reliable and dependable solution for residential, commercial, and industrial applications. It is designed to provide peace of mind and protection from potential dangers associated with electrical systems. With its simple working principle and adjustable trip time, it is a great choice for any situation.
