Its description decodes as a 3-pole (3P) unit with a fixed thermal-magnetic trip (TMF) adjustable from 175 A to 1750 A, fitted with front terminals (F F) and certified to UL/CSA standards.
The 175–1750 A adjustable thermal-magnetic trip covers a wide range of motor and feeder protection needs. The lower end suits a 175 A motor branch circuit; the upper end handles high-fault distribution. The fixed magnetic (instantaneous) pickup is set at the factory, so coordination studies should verify selectivity with downstream devices. UL/CSA listing means it meets North American panelboard and switchboard requirements without additional derating.
