Bulletin 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.
