Introduction

Circuit breakers are essential components of electrical power systems whose purpose is to protect those systems from damage due to overcurrents, short-circuits, or other faults. In order to be effective, they must be carefully selected and applied in accordance with their ratings and the requirements of the system. This article discuss the application field and working principles of UPG2-30195-1 circuit breaker, a high-amp, heavy duty circuit breaker manufactured by United Professional Group Limited.

Application

The UPG2-30195-1 circuit breaker is used to protect circuits and equipment against high overcurrents. This circuit breaker is designed for both 600VAC and 250VDC. It is widely applied for residential, commercial, and industrial applications. It also can be used in conjunction with other types of circuit protection devices, such as surge suppressors, fuses, and time delay relays, to protect the circuit and connected equipment from electrical energy overloads and surges. The UPG2-30195-1 circuit breaker is UL 489 listed and CSA certified, so it is suitable for use in a variety of environments. The enclosure is rated NEMA type 1, meaning it is suitable for use in dry or damp locations. This circuit breaker can be used as a main circuit breaker for motor control centers, switchboard assemblies, and other electrical control systems.

Operation

The UPG2-30195-1 circuit breaker utilizes a dual-break mechanism that includes two non-welded bridge contacts and a rotor armature. When the circuit breaker is activated, the contacts open simultaneously and the current is interrupted. The rotor armature is mounted on a plastic cap that is attached to the trip mechanism. This trip mechanism is also connected to the external knob for manual operation.When an overcurrent is detected, the rotor armature vibrates rapidly on its mount and causes the trip mechanism to open the contacts. Once the contacts are open, current will no longer flow through the circuit. The plastic knob will be in the off-position until it is reset by pushing it to the on-position.

Conclusion

The UPG2-30195-1 circuit breaker is a reliable, robust device that is suitable for a wide range of applications. Its dual-break mechanism provides effective and reliable protection from overcurrents, while its UL 489 listing and CSA certification make it suitable for use in a variety of environments. With its NEMA type 1 rating, it is suitable for use in dry or damp locations, and its manual reset switch makes it easy to reset after an overcurrent has been detected.
