ABB XT1HU3020AYD000XXX ReliaGear Circuit Breaker

ABB SACE Tmax XT ReliaGear XT1HU3020AYD000XXX is a plug‑in molded‑case circuit breaker rated 3‑pole, 20 A for 480 V AC systems, built on the XT13 frame with a TMF (thermal‑magnetic) trip unit and UL/CSA listing. It delivers a 65 kA short‑circuit interruption rating at 480 V, making it suitable for protecting feeders and motors in commercial and light industrial power circuits. The device accepts load‑side connections for a single #10 to 2/0 AWG conductor and is designed for use in ReliaGear neXT panelboards and ReliaGear SB switchboards, requiring a bus‑rail mounting accessory if not already installed in ReliaGear equipment. This specific part number confirms 20 A, 3‑pole, 480 V operation within ABB’s Tmax XT family, reinforcing ABB’s ReliaGear protection platform for reliable low‑voltage distribution.
