To protect electrical systems from overloading or to monitor large loads by means of a metering instrument, SES Current Transformer (CT) plays a very important role. It provides the necessary tools to measure the actual load current and reduce its values by means of a transformation ratio to a manageable value.  Therefore, selections of accurate and reliable CTs are very crucial.

SES range of PVC tape insulated metering and protection CTs are designed and manufactured to cater for wide range of applications.  Its quality has been proven and tested to IEC: 44-1 (1996), ASTA Certified & CE Mark Certified to UL. The standard rated secondary current is 5A.
