Current transformer CT 160/5 A diameter 21 / 16x12.5 412105

Current transformer – precise measurement and installation protection

The CT 160/5 A current transformer is a reliable device used to measure current in electrical circuits and provide protection against overloads and short circuits. Its design, based on proven solutions from Legrand, guarantees accuracy and safety of operation. Designed for use in industrial, commercial and residential installations.

Construction and application

The CT 160/5 A current transformer converts a high primary current (160 A) to a lower, safe secondary current (5 A), which can be measured by standard meters and relays. This allows monitoring of the installation load without the need to directly connect measuring devices to the high-current circuit. The passage diameter of 21 mm allows for convenient cable routing, and the 21 x 21 mm hole dimensions ensure compatibility with most standard switchboards. The device has a screw connection of the secondary circuit, which facilitates assembly and connection.

Application of the current transformer:

• Measurement systems: Accurate measurement of electricity consumption.
• Installation protection: Cooperation with protective relays against overloads and short circuits.
• Industrial automation: Monitoring the load of motors and other devices.
• Commercial and residential buildings: Control of energy consumption in public facilities and single-family homes.

Key features and benefits

• High accuracy: Accuracy class 0.5 ensures precise measurements, which is crucial in billing and energy quality control systems.
• Safety of use: It has touch protection, minimizing the risk of electric shock during operation and maintenance.
• Legalization: The device is legalized, which confirms its compliance with applicable standards and legal regulations – important when settling accounts with the energy supplier.
• FS 5 overcurrent factor: Allows for short-term exceeding of the rated current without damaging the device, which is particularly important when starting devices with motors or other pulsed loads.
• Low power consumption: Energy consumption at 3 W minimizes energy losses in the installation.
• Solid construction: Ensures long-lasting and reliable operation in various environmental conditions.
