Current transformer 1000/5A 5VA class 1 SRE10005

Current transformer for busbar systems

This current transformer, with a transformation ratio of 1000/5A, is designed for use with busbar systems. It enables safe and precise current measurements in high-current circuits, transmitting a signal proportional to the measured current to measuring and protection devices. Accuracy class 1 ensures measurement reliability, which is crucial in applications requiring high precision.

The transformer is characterized by a rated power of 5 VA, which means it can provide sufficient energy for connected secondary devices. The design provides for snap-on mounting, making installation and removal quick and convenient. The use of touch protection in the device increases safety.

Application and benefits:

• Current measurement: Enables precise current measurement in high-current circuits up to 1000A.
• Protection: Works with protection systems, protecting the installation against overloads and short circuits.
• Mounting: Quick snap-on mounting on a DIN rail or mounting plate – saves time during installation.
• Safety: Provides protection against accidental contact with live conductors.
• Versatility: Suitable for use in industry, energy, and commercial and residential construction.
• Compatibility with devices: Compatible with various meters, relays and energy monitoring systems.

Construction and parameters:

The transformer has a screw connection of the secondary circuit, which ensures a secure and durable electrical connection. Its compact dimensions (hole height 60 mm, hole width 41 mm) allow installation even in limited spaces. The passage diameter is 40 mm, allowing the passage of cables of appropriate thickness. The FS 5 overload factor means that the transformer can temporarily withstand currents significantly exceeding the rated value without damage.

It is worth noting that the device is not legalized – this means that it is not intended for applications requiring official confirmation of measurement accuracy (e.g. settlement with the energy supplier). However, accuracy class 1 ensures high precision in most typical industrial and commercial applications.
