ABL SURSUM 3DU3 3 Pole Circuit Breaker Switch

ABL 3DU3 is a 3-pole circuit breaker switch from the Sursum D family, rated at 3 A. This three-pole device combines circuit-protection and switching in a single enclosure, designed to interrupt all three conductors in a three-phase circuit and provide a clear, manual isolation point for energized equipment. The model name indicates a 3-pole configuration with a 3-amp rating, making it suitable for protection and disconnection duties in control panels, motor starters, and other industrial electrical assemblies that require three-phase protection. As part of the Sursum D lineup, the 3DU3 is intended for applications where reliable three-pole interruption is needed within compact form-factor equipment. When selecting this part, confirm compatibility with your panel or cabinet and ensure the device's current rating aligns with the protected load. Common uses include protecting three-phase loads in motor control panels and industrial equipment.
