Industrial CT101-500 Current Transformer

Industrial CT101-500 Current Transformer from Amran is a low-voltage instrument transformer designed for precise current sensing in 60 Hz power systems. It delivers a 50:5 primary-to-secondary ratio (50 A primary, 5 A secondary), making it well suited for metering, relays, and protection circuits in panel-mounted switchgear. This CT101-series device supports 60 Hz operation and carries an insulation rating of 0.6 kV with a Basic Impulse Level of 10 kV, aligning with typical industrial and utility installation requirements. Catalog references such as 35545A318 are associated with this model, and it belongs to Amran’s CT101 family of current transformers, which Amran documents as low-voltage transformers intended for switchgear and general-purpose instrumentation. Common applications include energy metering, panel instrumentation, and protection relay circuits where a 5 A secondary current provides a straightforward interface to standard meters and relays.
