ABB 1SFL557001R7222 Dual Auxiliary Contactor

ABB 1SFL557001R7222 Dual Auxiliary Contactor is a 3-pole AF300-series power contactor rated for 30 A, designed to switch line currents in industrial automation while providing two built-in auxiliary contacts for control signaling. This variant uses a DC coil with a voltage range of 20–60 V, enabling compatibility with multiple control-voltage systems in control cabinets and machine panels. The compact AF300 frame is intended for panel mounting and is part of ABB's family of IEC-rated contactors, delivering reliable switching of three‑phase loads when paired with the corresponding main contacts. The 1SFL557001R7222 order code identifies this dual auxiliary configuration, making it suitable for interlocking, sequencing, or status feedback in automation circuits. Common applications include conveyors, pumps, fans, and other machinery that require coordinated motor control and auxiliary feedback within a single device. This model is typically used in new installations or as a replacement part within ABB's AF300 product lineup, offering a standardized, space-efficient solution for control-panel design.
