Pioneer Instrumentation 55 RL-501 Current Transformer

The Pioneer Instrumentation 55 RL-501 is a compact, split-core current transformer designed for accurate measurement of AC currents in industrial and commercial electrical systems. It features a 500:5 ratio, making it suitable for applications requiring step-down current transformation for metering, protection, and control purposes. With a voltage rating of 600 VAC, this transformer is ideal for use in power distribution panels, motor control centers, and energy management systems. Key benefits include easy installation without disconnecting conductors due to its split-core design, high accuracy for reliable readings, and robust construction for durability in harsh environments. Compared to similar products like those from ABB or Schneider Electric, the 55 RL-501 offers cost-effective performance with good thermal stability and low burden. Drawbacks may include limited suitability for very high-current applications beyond its rating and the need for proper calibration to maintain accuracy. This model supports non-invasive current monitoring, reducing downtime during setup. Based on attached images, the unit appears used with minor wear, exposed wires, and no visible damage, suggesting it's in good working condition for refurbishment or direct use. No parent/child assets are evident. For detailed specs, refer to manufacturer datasheets; estimated market price for used units ranges from $40-80 USD based on recent online listings from sites like eBay and industrial surplus vendors.
