The OC series split core power current transformers use high magnetic induction grain-oriented silicon steel strip cores processed by high-temperature heat treatment under nitrogen protection, wound with pure copper enameled wire. The housing is made of halogen-free PC engineering plastic with high heat resistance (120℃). With reliable safety performance and easy installation via pressure plate fixing, they are widely used in power transformation and monitoring projects.
Primary current ranges from 100A to 5000A, secondary current available in 1A and 5A, 0.2-2 accuracy classes provided
All cores experience high-temperature heat treatment under nitrogen protection, ensuring superior performance and stable precision
Halogen-free high impact flame retardant PC housing with excellent safety performance and aesthetic appearance
Heat resistant to 120℃, suitable for harsh working environments with high temperature requirements
Convenient installation with pressure plate fixing, firm and reliable fixation
