Rockwell Automation 1492-SPM MCB1P, 50A Curve C, 277V AC, 48V DC

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
Suitable for extreme ambient conditions
