The OPCT160BD splitcore current transformer is a windowtype CT designed for current measurement in electrical systems. Its splitcore, windowstyle design allows installation around an existing conductor without disconnecting equipment, enabling quick retrofits and reduced downtime. This CT provides a 5A secondary output and is offered in multiple primary current ratings to cover a wide range of current applications, including the OPCT160BD4000A 5A variant. Key benefits Quick Retrofit: splitcore/window design enables clipping around a conductor without interrupting power. Wide Primary Range: available in 1000A, 2500A, and 6000A primary ratings (with 5A secondary), plus the OPCT160BD4000A 5A variant. Standard Secondary: 5A secondary output for compatibility with common meters, data loggers, and instrumentation. Practical Window Type: suitable for current measurement in a compact form factor that fits around existing cables. Key attributes Model: OPCT160BD (splitcore windowtype current transformer) Primary current ratings: 1000A, 2500A, 6000A (with 5A secondary); OPCT160BD4000A 5A variant available Secondary rating: 5A Configuration: splitcore / windowtype CT for easy installation around conductors Application: current measurement in electrical systems and instrumentation Applications and use cases Metering and monitoring in electrical panels and distribution boards Current measurement for industrial motors and current loads Energy management and monitoring in facilities such as data centers, commercial buildings, and HVAC systems Notes on use Designed for current measurement with a 5A secondary; suitable for integration with standard instrumentation and sensing equipment that accepts a 5A input. Different primary ratings (1000A, 2500A, 6000A, and 4000A variants) provide flexibility to match your circuit's current requirements.
