The electrical systems within commercial, industrial, and residential settings are often protected by circuit breakers. The GE Power Break II, a stalwart in this field, provides that vital protection. Understanding the specific characteristics, functionalities, and safe operating procedures outlined in its manual is not merely helpful; it’s essential. Neglecting this knowledge can lead to operational inefficiencies, potential equipment damage, and, critically, pose significant safety risks. This guide will walk you through everything you need to know to make the most of your GE Power Break II circuit breaker.
Poles, Trip Unit, Operating Mechanism, Arc Chutes, and Terminals
The heart of the GE Power Break II lies in its key components. The first is the poles. These are the conducting paths through which current flows. Each pole interrupts the flow of current, effectively isolating a portion of the electrical system when necessary. The number of poles dictates the breaker’s functionality, for example, one pole for single-phase systems and three poles for three-phase systems.
Next, there’s the trip unit. This is the intelligent component responsible for detecting and responding to abnormal electrical conditions. The trip unit monitors the current flowing through the circuit and, if it exceeds a predetermined threshold (due to an overload or short circuit), it signals the operating mechanism to open the circuit. Various trip unit technologies exist, including thermal-magnetic and electronic versions, each tailored to different applications and protection needs.
The operating mechanism is the physical apparatus that quickly opens and closes the circuit breaker. It is typically spring-loaded, allowing for a rapid and decisive response to trip signals. The mechanism ensures that the circuit is interrupted quickly and safely in the event of a fault.
Arc chutes play a crucial role in suppressing the arc that forms when the circuit breaker opens under load. The arc is the highly energized plasma that develops as the circuit is broken. Arc chutes, typically constructed from insulating materials, confine and divide the arc, quenching it rapidly to minimize damage and maintain the integrity of the breaker.
Finally, the terminals provide the physical connection points for the incoming and outgoing conductors. They must be securely connected to ensure reliable current flow and to prevent overheating. Proper terminal connection is critical for both safety and optimal breaker performance.
Types and Ratings
GE Power Break II circuit breakers are available in various types, each designed to meet specific application requirements. Thermal-magnetic breakers offer protection against both overload (sustained overcurrent) and short-circuit (instantaneous overcurrent) conditions. Electronic trip unit breakers offer a higher degree of control and flexibility. These breakers often allow for adjustable trip settings, enabling users to customize the protection characteristics to match the specific requirements of the connected equipment. They can also provide advanced features, such as ground fault protection and communication capabilities.
Understanding the rating and specifications is fundamental to using the GE Power Break II safely and effectively. The voltage rating indicates the maximum voltage the breaker is designed to handle safely. Exceeding the voltage rating can lead to arcing and equipment failure. The current rating specifies the continuous current the breaker can safely carry without tripping. The interrupting capacity (IC), a critical parameter, represents the maximum fault current the breaker can safely interrupt without damage. Always ensure that the breaker’s IC rating is sufficient for the potential fault current in the application. Failing to do so can lead to catastrophic consequences.

Operation and Use
The GE Power Break II’s primary function is to safeguard electrical circuits from overload and short-circuit conditions. Understanding its operation is vital.
Understanding the trip unit is fundamental. A thermal trip unit responds to sustained overcurrents (overloads) by heating a bimetallic strip. When the bimetallic strip reaches a specific temperature, it bends and trips the breaker. A magnetic trip unit, on the other hand, responds to instantaneous overcurrents (short circuits) by using a magnetic field to actuate the trip mechanism. Electronic trip units provide the most sophisticated control, allowing for adjustable trip settings and other advanced features. The specific characteristics of the trip unit will dictate how the breaker reacts to different fault conditions.
Operating procedures are straightforward. To close the breaker, push the handle to the “ON” position. To open the breaker, push the handle to the “OFF” position, or the breaker may trip automatically in the event of a fault. If the breaker trips automatically, you must identify the cause of the fault and rectify it before resetting the breaker. When the breaker trips, there will be a visual indication, such as a flag or a colored indicator appearing in a window. Some breakers also have indicator lights or other alarm signals.
