ABL SURSUM 1BU20 Circuit Breaker

ABL 1BU20 circuit breaker is a single-pole, 20-amp protective device designed to interrupt current on a single conductor in an electrical panel or control enclosure. As part of ABL’s family of protective devices, this 1-pole breaker provides overcurrent protection for a dedicated branch circuit, helping prevent wiring damage and equipment fault from overloads. The 20-amp rating specifies the maximum continuous load the breaker is intended to carry before tripping, enabling designers and technicians to match circuit capacity with circuit conductors and connected equipment. Use cases typically include protecting branch circuits feeding lighting, receptacles, or control equipment within standard electrical panels, where a compact 1P format supports straightforward installation and replacement. When selecting a replacement or upgrade, ensure the form factor and mounting arrangement align with the panel or enclosure specified by ABL/Rockwell Automation, and verify compatibility with the panel’s labeling and protective device requirements.
