0.66 Dia16mm 100A/40mA Current Transformer Key benefits - Precise scaling: converts a primary current of 100 A to a secondary output of 40 mA, providing a reliable, proportional signal for monitoring and measurement equipment. - Compact form factor: 16 mm device diameter fits tight spaces and panel cutouts, simplifying installation where larger CTs cannot be used. - Accurate measurement: marked 0.66 accuracy class for consistent readings where moderate accuracy is required. - Easy integration: designed for use with instruments and control systems that accept a 40 mA secondary input, enabling direct compatibility without extra signal conversion. Features and attributes - Function: Current transformer with a transformation ratio of 100 A → 40 mA for current sensing and measurement. - Rating: 100A/40mA nominal. - Accuracy: 0.66 (as specified). - Size: Diameter 16 mm, compact footprint suitable for constrained installation environments. - Construction: Compact CT housing designed for panel or inline placement (material details per manufacturer specification). How it solves problems - Eliminates bulky CTs: small 16 mm diameter reduces space requirements in tight control panels and enclosures. - Provides a usable secondary output: delivers a 40 mA secondary signal compatible with instruments and controllers that require mA-level inputs, avoiding additional converters. - Maintains measurement integrity: the 0.66 accuracy class helps ensure dependable readings for monitoring, logging, and basic protection applications. Typical applications - Power monitoring in control panels and distribution boards where space is limited and a 40 mA secondary is required. - Retrofit installations to add current sensing to existing equipment that accepts mA-level inputs without changing primary conductors. - Current measurement for industrial equipment monitoring, metering modules, or building energy management systems that support a 40 mA secondary.
