    Product Details

    The Rockwell Automation 1492-SP thermal magnetic Supplementary Protectors provide overcurrent protection for equipment where branch circuit protection is already provided, or is not required. These devices are also Miniature Circuit Breakers as defined by IEC Standards. These supplementary protectors are offered as a broad portfolio of pole variants, current ratings, and trip curves to match the appropriate level of protection for your application. They may be used with UL 508 Listed bus bars for convenience in panel assembly, a wide range of left-, right- and space saving bottom-mount accessories, and lock out attachments for safety during maintenance.

    Current limiting
    Fast breaking time
    Existing installations can be easily upgraded to include an auxiliary using the bottom mounted auxiliary contact options, which require no DIN Rail space
    40 °C calibration temperature (UL/CSA) eliminates need to derate for 508A industrial control panel installations
    Installation of up to six accessories on the same circuit breaker
    Dual terminals provide a more secure connection of up to four wires, or two wires and a bus bar
    Superior shock and vibration resistance to prevent nuisance tripping
    Terminal design helps prevent wiring misses by directing wires into the terminal openings, even while tightening
    Reversible line and load connections
    Single and multi-pole toggle mount lock out attachments available for Lockout/Tagout (LOTO)
    RoHS compliant and fully-recyclable device
