The A1A080TW-2 is a 2-pole thermal-magnetic circuit breaker from the A1A 100 TMF series, with a fixed thermal trip of 80 A and a fixed magnetic trip of 800 A. The description string A1A 100 TMF 80-800 2P F F UL confirms the frame (A1A 100), the trip type (TMF — thermal-magnetic fixed), the poles (2P), the fixed thermal and fixed magnetic settings, and the UL listing. This is a panel-mount device sized for branch-circuit protection in industrial control panels.
The 80 A continuous rating and 800 A magnetic trip suit it for feeder circuits feeding multiple downstream loads or a single large motor branch.
