Allen-Bradley 500L-A0H92 Lightning Contactor

Allen-Bradley 500L-A0H92 Lightning Contactor is a two-pole, NEMA Top Wiring, open-style lighting contactor from Rockwell Automation’s 500L family, size 0, designed for 200–208 V AC at 60 Hz lighting loads. The coil is rated for 200–208 V AC (60 Hz), and the unit provides a per-pole load rating of 15/20 A across two power poles, making it suitable for commercial lighting circuits in offices, retail, and light industrial environments. It operates as an electrically held (hold-in) contactor, a characteristic of the 500L line, which supports reliable control in push-button or PLC-based lighting control schemes. As a genuine Allen-Bradley/Rockwell product, it is documented on Rockwell’s official product pages and widely stocked by distributors such as Kirby Risk and Radwell, which corroborate its size 0 designation, open construction, two-pole configuration, and the 200–208 V coil rating. This model is commonly referenced in North American 60 Hz lighting control applications, offering straightforward field wiring and compatibility within the 500L family’s maintenance and interchange ecosystem.
