Schneider Electric SE QO320PL Circuit Breaker

Schneider Electric's Square D QO320PL is a 3-pole, 20-amp, 240-volt miniature circuit breaker designed for plug-in installation in QO load centers. It delivers a 10 kA interrupt rating at 240 V and uses a thermally magnetic trip to protect three‑phase circuits from overloads and short circuits. The PL suffix denotes Powerlink remote-control compatibility, enabling remote tripping when paired with the Powerlink accessory in compatible panels, and it integrates into the standard QO plug‑on family for straightforward installation in 3P, 240V systems. This breaker is commonly used to protect 3‑phase feeders and motors in light commercial or multi‑family electrical distributions, where a compact, reliable 20 A protective device is required for three‑phase loads. Designed for operation with 50/60 Hz power in typical North American electrical systems, the QO320PL is a staple choice when remote control capability and robust short‑circuit protection are needed in a 240V, 3‑phase environment.
