Carling Technologies AB3-B0-24-620-2D1-C Circuit Breaker

Carling Technologies AB3-B0-24-620-2D1-C is a three‑pole hydraulic‑magnetic circuit breaker designed for panel‑mount installation in electrical control panels and equipment. It is rated for 20 A and accepts 277 VAC and 80 VDC, enabling protection for loads across both AC and DC supplies. The device uses a lever‑operated mechanism and a hydraulic delay combined with a fast magnetic trip to suppress nuisance trips while still delivering fast protection during faults. This RoHS‑compliant unit carries UL, CSA, and CCC certifications, aligning with common safety and compliance requirements for industrial installations. As part of Carling’s A‑Series hydraulic‑magnetic family, the AB3‑B0‑24‑620‑2D1‑C is intended for three‑pole configurations to protect circuits in control panels or industrial equipment that operate up to 277 VAC or 80 VDC at a 20 A rating.
