Description

Indoor Low Voltage Current Transformer – 0.72 kV

This Indoor Current Transformer (CT) is designed for low-voltage measuring and protection applications up to 0.72 kV system voltage. Engineered for reliability and accuracy, it supports a rated primary current range of 50A to 4000A with a standard secondary output of 1A or 5A, making it suitable for a wide range of industrial, utility, and commercial metering systems.

With rated outputs (burdens) from 1.5 VA to 40 VA, this CT meets stringent accuracy requirements for both metering (accuracy classes: 0.2s, 0.2, 0.5, 0.5s, 1.0, 3.0) and protection (accuracy classes: 5P5 to 5P30, 10P5 to 10P30, and PS(X)). It is capable of withstanding test voltages of 3 kV and 8 kV, with short-time thermal current ratings up to 60 times In for 0.5 seconds, and dynamic current withstand up to 2.5 times Ith.

Designed for indoor installation, this CT ensures consistent performance in controlled environments and is ideal for use in switchboards, control panels, motor control centers, and energy monitoring systems.

Specifications:

– Wide current range up to 4000 A for versatile system integration
– Dual-use accuracy classes for both protection and metering
– High dielectric strength with 3 kV / 8 kV test voltages
– Supports both 50 Hz and 60 Hz network frequencies
– High thermal and dynamic current withstand capability
– Compact indoor design for switchboards and control panels
