Overview This listing is for a used surplus Square D KA262225AC molded case circuit breaker (MCCB), Type KA, 225 A, 3-pole, I-Line plug-in style. The breaker is a thermal-magnetic unit rated for 600 V, with high interrupting capacity suitable for industrial and commercial branch/feeder protection in I-Line panelboards and switchboards. Used surplus – pulled from service; good functional condition with intact internals and no visible arc damage or heavy wear. Some units in this batch show cosmetic damage to the manufacturer labeling (scratches, scuffs, or partial fading on the nameplate), but ratings remain fully legible and the breaker mechanism operates smoothly.
Key Features
Manufacturer: Square D (by Schneider Electric)
Model / Catalog: KA262225AC (Type KA frame, S2 interrupting level, I-Line plug-in)
Amperage Rating: 225 A
Poles: 3-Pole
Voltage Rating: 600 VAC (50/60 Hz); suitable for 240/480/600 V systems
Interrupting Rating (AIC):
65 kA at 240 VAC
25 kA at 480 VAC
10 kA at 600 VAC
Trip Type: Thermal-magnetic (fixed)
HACR Rated: Yes
Wire Range: #4 AWG–350 kcmil Cu/Al (per lug label)
Terminal Torque: 29 N·m (AL250KA lugs)
