BreakMaster™ Load Interrupter Switchgear

BreakMaster load interrupter switchgear, featuring the advanced interrupting technology of the VersaRupter® switch, provides dependable, economical load switching and protection for medium voltage circuit applications from 2.4 kV through 15 kV in 600 A, 40 kA load interrupting ratings. The 1200 ampere rating is available using an alternate switch.

 

Used mainly as a primary or secondary disconnect switch for transformers, the BreakMaster load interrupter switchgear is available in a variety of configurations that also make it useful for specific distribution needs. It can be inserted as a main or feeder switch in Advance® switchgear or Limitamp motor controller lineups. Fault current protection is available using a complete line of current limiting or expulsion fuses.

 

BreakMaster load interrupter switchgear with Automatic Transfer Switch

Advanced digital technology and motor operators allow BreakMaster load interrupter switchgear to switch to emergency power when normal power fails, offering a cost-effective alternative to breaker options.
