Low Voltage Current Transformers

Product at a glance

Our comprehensive range of reliable and accurate current transformers is ideal for LV industrial, commercial and residential metering applications. The current transformer range is an essential component of the AC measurement system, designed to work optimally with our panel instruments, transducers and energy meters. Our CTs are made in accordance with stringent plant quality assurance procedures, which comply fully with applicable standards (IS: 2705 & IEC: 60044-1). The range includes metering class CTs, protection and PS class CTs for primary current from 5 A to 5000 A and secondary current 5 A/1 A. Our CTs are available in accuracy classes 0.2s, 0.5s, 0.5, 1.0 (others on request) and with burden ranging from 1 VA to 50 VA.

Features
  • Suitable for consumer and distribution transformer metering
