This is a 5A clamp current transformer current sensor with a 300/5A ratio. It provides accurate, non invasive current measurement with a clamp that makes installation quick and simple. Key benefits - Non invasive current sensing: clamp around an existing conductor to measure current without disconnecting the circuit. - Accurate current measurement: 300/5A ratio delivers precise readings for systems requiring a 5A secondary output. - Easy installation: the 5A clamp design allows fast mounting and wiring with minimal disruption. - Compatibility with CT inputs: suitable for current sensing applications that require a 300/5A current ratio and CT style measurement. - Clear indication of primary current: when the primary current is 300 A, the secondary current is 5 A, enabling straightforward interpretation by compatible meters or controllers. - Reliable performance: designed to provide a consistent current signal for monitoring and protection tasks in a variety of setups. What you get and how it works - Current ratio: 300/5 A - Clamp style sensor: clamps around a conductor to capture the magnetic field and generate a proportional secondary current - Primary current reference: up to 300 A at full scale, which corresponds to a 5 A secondary current - Output: 5 A secondary current suitable for CT input devices and current monitoring equipment Use scenarios - Industrial motor monitoring: install around the motor feed to detect overload conditions or imbalances without interrupting operation. - Building energy management: integrate with metering or control systems to analyze load distribution and identify high usage equipment. - Power distribution protection and metering: apply in panels where CT inputs are used by protective relays, data loggers, or energy meters to monitor overall current flows. Notes - Designed for applications that use a 300/5A current ratio - Clamp around a single conductor to measure current non invasively - Suitable for integration with equipment designed to accept a 5A CT output This description stays consistent with the original product specifications and functions: a 5A clamp current transformer current sensor with a 300/5A ratio intended for accurate, easy to install current sensing across a range of related applications.
