Current transformer 150/5A 2.5VA class 1 SRA01505

Current transformer – precise measurement and installation protection

This current transformer, with a rated primary current of 150A and a secondary current of 5A, is a reliable tool for measuring current in electrical installations. Its compact design and accuracy class 1 make it ideal for both industrial and commercial building applications. This transformer allows for safe and precise monitoring of the load, which is crucial for effective energy management and ensuring the continuity of device operation.

Features and application

Designed to work with LVSG NH00 non-current switchboards, this transformer enables current measurement without the need to interrupt the circuit. Its through-hole design ensures easy installation and convenience. Thanks to the overload factor of FS 5, this transformer copes well with short-term overloads, which increases its durability and reliability. The rated apparent secondary power of 2.5 VA guarantees stable operation with various measuring and protection devices.

• Precise measurement: Accuracy class 1 ensures reliable current readings.

• Safety: Protection against touch minimizes the risk of electric shock during operation.

• Versatility: Designed for LVSG NH00 non-current switchboards, but can be used in many other applications.

• Durability: Made of high-quality materials, resistant to mechanical damage and environmental conditions.

• Easy installation: Through-hole design simplifies installation in existing electrical installations.

• Device compatibility: Rated apparent power of 2.5 VA ensures compatibility with a wide range of meters and relays.

Design and parameters

The transformer has a single primary input and a secondary circuit connection made using a screw connection – which facilitates connection to the measurement or protection system. The passage diameter is 20 mm, and the hole width is 29.5 mm, which allows it to be adapted to different cables and wires. It should be noted that the product does not have a copper busbar or a snap-on mount, and is also not legalized – which means it is not intended for billing with the electricity supplier. Its main task is to monitor the load inside the installation and protect against overloads and short circuits.
