2. MV Metal-enclosed load interrupter switchgearFebruary 7, 2023Slide 2BreakMaster and BreakMaster VDefinitionLoad Interrupter Switchgear (LIS) consists of an air insulated disconnect switch mounted in a metal enclosure. The BreakMaster™ LIS is used to provide safe switching and circuit protection where an infrequent means of disconnecting is required. A LIS can provide fault current protection by using various types of fuses. It is commonly used in a single circuit for on/off control of a transformer, duplex switching, and selector switch applications. A switch can also be grouped in a lineup configuration with other medium voltage distribution equipment.

7. MV Metal-enclosed load interrupter switchgearFebruary 7, 2023Slide 7BreakMaster and BreakMaster VOperationA load interrupter switch consists of a two-position (open/closed), three-pole switch. The switch utilizes a quick make/quick break spring-charged mechanism for both opening and closing. The speed at which the switch opens or closes is independent of the speed at which the operator handle is moved.The load interrupter switch is operated externally from the front of the switch enclosure. The switch is connected to the power source on one side and to the load on the other side. When the switch is actuated, the switch blades disengage and interrupt the flow of electricity.
8. February 7, 2023Slide 8BreakMaster and BreakMaster VThe BreakMaster load interrupter switchgear consists of a rigid, bolted frame construction enclosure. This enclosure is constructed of 11-gauge sheet steel, including the doors, back panels, and side panels All steel doors have concealed hinges and captive screw, or quarter-turn latches as standard. A foot operated doorstop is also included. Each switch compartment and the fuse compartment are provided with individual or “split” doorsThe standard indoor depth on the enclosure is 50 inches. An optional 60-inch enclosure is available for special applications or for mounting additional devices. Each standard switch section is 35 inches wide. The split rear and side covers provide easy access. Also, the top access covers are removable for easy accessConstructionMV Metal-enclosed load interrupter switchgear
9. MV Metal-enclosed load interrupter switchgearFebruary 7, 2023Slide 9BreakMaster and BreakMaster VThe BreakMaster load interrupter switchgear includes a mechanical switch and door interlock as standard features. These prevent the opening of the doors when the switch is in the “ON” position. They also prevent switch from closing when the door is openAdditionally, each switch comes with provisions for up to six optional key interlocks. These interlocks provide a mechanical method to interlock two or more devices, utilizing a removable key which can only be inserted in one location at a timeFor example, the BreakMaster Load Interrupter switch can be key interlocked with the main circuit breaker of a switchboard on the secondary side of a transformerInterlocks
10. MV Metal-enclosed load interrupter switchgearFebruary 7, 2023Slide 10BreakMasterThe standard orientation has the BreakMaster load interrupter switchgear on the left side of the transformer when facing the front of the transformer. A reverse orientation, with the switch on the right side, is also availableNote: If the switch is a secondary switch, that is, on the low voltage side of a transformer, it should be specified as a line-up with a low voltage transition sectionThe switch is used to isolate the transformer from the incoming service or to isolate the load circuits from the transformer. This configuration is available in single, duplex, and selector switch configurationsTransformer disconnect
11. February 7, 2023Slide 11BreakMasterDuplex switchThe duplex switch provides on/off switching, utilizing two load break switch sections (one fused, one unfused) connected to a common load. Mechanical interlocks (key interlocks) prevent both switches from being closed at the same timeThe duplex switch functions as a switch between two power sources, such as a primary and auxiliary power sourceThe features of a duplex switch include: Two sections 35-inches wide, connected togetherOne set of power fusesFour key interlocks included as standardMV Metal-enclosed load interrupter switchgear
