Problems solved by technology

However, this imposes undesirable constraints on the space within the enclosure
Furthermore, the free discharge of hot gases from the circuit breakers can adversely increase the internal pressure within the enclosure, especially when these circuit breakers are restrained as in many applications
The pressure increase is exacerbated by the high rate of pressure rise due to free exhaust

Embodiment Construction

[0023] figure 1 An exemplary circuit breaker assembly 10 is shown that utilizes components and features according to the present disclosure. Circuit breaker assemblies may be used in a wide range of environments including industrial settings, commercial settings, and in a variety of applications such as manufacturing, material handling, transportation, process industries, and the like. In many applications, circuit breaker assemblies will be installed in the enclosure 12, and the enclosure or components contained in the enclosure may in turn be installed in larger enclosures and systems. In some industrial environments, for example, such circuit breaker assemblies may be installed in a motor control center (MCC) used to control the operation of one or more motors driven to perform automated tasks. In many of these applications, an operator handle 14, knob or similar mechanical device will be provided to allow opening and closing (and resetting) of the circuit breaker during n...

Abstract

A gas directing system for a circuit breaker (24) is disclosed. The system includes an insulative housing (68) that fits over vents (52) that convey hot gases upon operation of the circuit breaker. The housing has phase partitions that separate phase sections from one another, and transverse partitions that separate a venting section for each phase from terminal sections. Gas diverting structures are provided in the venting sections that redirect hot gases towards apertures (72) through which the gases vent. The overall structure may be much lower profile than previous design spacing requirements.

Description

technical field [0001] The present invention generally relates to the field of circuit breakers and gas guiding and venting devices for circuit breakers. More specifically, the present invention relates to systems for redirecting and venting hot gases and conductive materials during circuit breaker operation. Background technique [0002] There are many applications in industry for switchgear including circuit breakers. Typically, circuit breakers provide protection for wiring and various downstream components by limiting current flow from a power source, such as the grid. In many industrial environments, three-phase circuit breakers are used in which three-phase power is routed to the load through the circuit breaker hardware. The circuit breaker can be closed to complete the power path to downstream equipment such as motor drives, switchgear, motor starters, and the like. When certain conditions occur, the circuit breaker can be opened, thereby interrupting the current ...
