UPL12-1REC4-28049-1 Circuit Protection

Circuit breakers are essential electrical safety tools. In order to better understand their working principles and applications, it is important to become familiar with the UPL12-1REC4-28049-1 circuit breaker. This device is a molded case circuit breaker with an integrated thermal-magnetic trip unit rated up to 120/240Vac and 50 amperes. It is composed of two key components, namely the magnetically operated trip unit and the thermal-magnetic trip unit. Both components are used to detect over-currents and interrupt the circuit, thereby providing an effective way to protect electrical systems, personnel and property.

The magnetically operated trip unit is a relay-type circuit breaker that opens the circuit by means of a solenoid when over-current is detected. The solenoid is activated when the current exceeds a certain threshold, thereby causing the contacts of the trip unit to separate and thus interrupting the circuit. This device is designed so that it will keep a circuit protected, even if the current surpasses the trip setting. This way, personnel and property are shielded from dangerous current levels.

In addition to the magnetically operated trip unit, the UPL12-1REC4-28049-1 circuit breaker also features a thermal-magnetic trip unit. This device is equipped with a bimetallic strip that is heated when an over-current is detected. The heat generated from the strip causes the switch contacts to separate, interrupting the flow of electrical current. In addition to detecting over-currents, the thermal-magnetic trip unit also guards against short circuits and ground faults. Both components are combined in the same breaker to ensure maximum protection.

The UPL12-1REC4-28049-1 is a reliable solution for residential and commercial applications, such as lighting, heating, air conditioning, refrigeration and motor overloads. It can be both manually and remotely operated, and it features a wide range of settings to provide greater control of the electrical system. The direct mount installation makes it easier to install and maintain, providing a more secure means of overload protection than its competitors.

In conclusion, the UPL12-1REC4-28049-1 is an effective, reliable solution for residential and commercial applications. It features a thermal-magnetic and magnetically operated trip unit to provide maximum protection against over-currents and other dangerous electrical events. It can be manually and remotely operated and is designed for use in a wide variety of situations. With its direct mount installation, it is a great choice for those looking to ensure safety in their electrical systems.
