The DRC3R48B400 is a miniature, solid-state, three-phase current transducer from Sensata. It features an open loop transformer, which is used to convert current signals into low level voltage signals. The DRC3R48B400 is designed for mounting onto a single-phase system; it allows for accurate measurements of current up to 400A in three-phase systems. It features a wide input voltage range of up to 400V, overload protection of 500% of the rated current, and a high accuracy of 0.5%. It has a small size, with a 42mm body length and 17mm diameter, making it suitable for use in restricted places. It is compliant with UL and CE standards, and is CE certified. Its protection class is IP20, making it suitable for indoor use. The DRC3R48B400 is a high-performance, reliable, and cost-effective solution for current monitoring.
