The ABB XT1N 160 TMD 32-450 3P F is a molded case circuit breaker from the XT1N series, carrying a 450A I3 instantaneous trip rating. The TMD trip unit gives you thermal-magnetic protection — thermal for overloads, magnetic for short circuits — and the I3 setting means the magnetic pickup is fixed at 10x In, so it clears hard faults fast without nuisance tripping on motor inrush. It's a three-pole unit, frame size 160, built for panelboard and distribution duty.
