5A Clamp Current Transformer is a clamp on current sensor for AC circuits. It provides a 300/5 A current ratio, meaning a primary current of up to 300 A generates a 5 A secondary signal. Key benefits - Noninvasive current sensing: clamps around a single conductor without breaking the circuit. - Accurate current ratio: 300/5 A to interface with standard 5 A sensing inputs. - Easy installation: compact clamp design for panel, cabinet, or equipment mounting. - Reliable monitoring: suitable for metering, protection, and load monitoring applications. Main attributes - Function: current sensor for AC current measurement - Current ratio: 300/5 A - Form: clamp on, non contact, single conductor - Compatibility: designed to feed sensing electronics that accept a 5 A secondary signal - Size and construction: compact clamp suitable for tight installations - Performance: provides a practical and dependable measurement signal for downstream electronics Use scenarios - Building energy management: monitor and log HVAC and major electrical loads for efficiency reporting - Industrial equipment: observe motor and drive currents to detect overloads or abnormal operation - Power distribution and protection: feed metering and protective relays with a 5 A secondary input for real time current data
