Description
The VE-CT40 single phase current transformer is designed for accurate monitoring of very high electrical currents in commercial, industrial, and utility environments. It is ideal for large-scale electrical systems where dependable measurement and robust construction are essential.
Built to handle demanding applications, the VE-CT40 provides a safe and effective way to measure high current loads without direct connection to live conductors. Its solid moulded case design and clear installation markings make it a reliable choice for long term use in high capacity distribution panels and industrial installations.
Features
The VE-CT40 supports primary current ranges from 400A to 1600A and offers either a 5A or 1A secondary output. This allows it to work with a wide range of standard energy meters, multifunction power meters, and protection relays used in large commercial and industrial systems.
The transformer has a compact but robust housing with an 85mm width, designed to suit high current applications while remaining practical for panel installation. It offers multiple cable aperture options, including 60 x 15mm, 50 x 30mm, and a 45mm round aperture. These options allow it to accommodate larger conductors and busbars commonly found in high load electrical systems.
A sealable terminal cover is included to protect wiring connections and support secure installation. Clear arrows moulded into the case body indicate the correct direction of primary current flow, helping reduce installation errors and ensuring accurate measurements.
The VE-CT40 is supplied with busbar fixings and mounting feet, providing secure and stable installation in distribution panels and electrical enclosures.
Details
The VE-CT40 series forms part of a large family of solid core single phase moulded case current transformers from Instruments. These transformers are engineered to deliver reliable performance, accuracy, and durability in professional electrical environments.
They are suitable for monitoring current flow in commercial buildings, industrial facilities, and utility installations. The VE-CT40 is designed to connect to any standard metering or relay product that requires a 5A or 1A secondary output. With primary current ranges from 400A to 1600A, this model is particularly well suited to main distribution boards, high capacity feeders, and large industrial equipment.
Ease of installation has been built into the design of the VE-CT40 series. Each unit is supplied with busbar fixings and mounting feet, allowing secure fitting in a range of panel layouts. Clear current direction markings moulded into the case help installers position the transformer correctly and minimise the risk of wiring mistakes.
