    Oil-immersed, low-voltage secondary circuit breakers

    FEATURES OF BREAKER ON BRACKET

    • Preadjusted - no linkage adjustments are required by the transformer manufacturer.
    • Ordered as a complete kit, one catalog number supplies the breaker, bracket, linkage and operating handle.
    • Rigid mounting bracket eliminates misalignment.
    • Special contact materials to reduce arcing and eliminate the possibility of contacts welding in service.
    • High interrupting capability to successfully clear bolted secondary faults without contact welding.
    • Rigidly interlocking contacts to give simultaneous interruption of both breaker circuit contacts.
  • For distribution transformers rated 10-167 kVA with secondary voltages of 120/240 or 240/480 single-phase.

    Some transformers rated 25 kVA and all rated 37.5 kVA and above, single-phase, feature magnetic trip circuit breakers.

    Three-phase circuit breakers are available from 15-150 kVA at 480 volts and below, and from 45-300 kVA at 480 volts.
