Schneider Electric FA26020AB 2 Pole Circuit Breaker

The Square D by Schneider Electric FA26020AB is a two‑pole, 20‑amp molded‑case circuit breaker from the FA/I‑Line family, rated for up to 600 V and designed to protect feeders in commercial and light industrial installations. It uses a thermal‑magnetic trip mechanism and employs AB phase configuration (A and B) with I‑Line line connections and load‑side lugs that accept 14–4 AWG aluminum or copper conductors. Interrupting capacities vary by voltage: up to 25 kA at 240 V, 18 kA at 480 V, and 14 kA at 600 V, providing robust protection against short circuits while meeting the FA series' specifications. Designed for use in compatible I‑Line panelboards, the FA26020AB uses a plug‑in I‑Line interface typical of Square D FA devices and is intended for reliable, code‑compliant protection of electrical feeders and equipment. The 80% continuous‑duty rating supports sustained loads within its 20 A, 600 V rating, and the model number FA26020AB identifies the precise 2P, 20 A, 600 V FA I‑Line breaker from Schneider Electric.
