Current transformer for busbar system 400/5 5VA class 1 non-legalized size BG 413 SRI04005

Current transformer for busbar systems

This current transformer, with a transformation ratio of 400/5, is designed for precise current measurement in electrical installations. The rated apparent power of 5 VA and accuracy class 1 ensure reliable readings, which is crucial for both professional installers and end-users who need accurate data on energy consumption. The device does not require legalization, simplifying its implementation and reducing costs.

Features and application

The through-type transformer with a 28 mm diameter hole allows mounting on busbars with a width of 40 mm and a height of 28 mm. Its design with a single primary input and screw terminals ensures easy and safe mounting and connection to the secondary circuit. The transformer is characterized by a dynamic current factor (FS) of 5, which means it copes well with short-term overloads, typical during engine starting or other high-power devices. The use of a transformer with touch protection increases safety.

Advantages in practice

• Precise measurements: Accuracy class 1 guarantees reliable current readings, essential for monitoring load and optimizing energy consumption.
• Easy installation: Snap-on mounting simplifies quick installation on DIN rails or a mounting plate.
• Safety of use: Touch protection minimizes the risk of electric shock during operation and maintenance.
• Versatility: Designed for use in busbar systems, ideal for both industrial and commercial installations.
• Overload resistance: Dynamic current factor FS 5 allows trouble-free operation in conditions of short-term current surges.
• Wide operating temperature range: The ability to operate in a temperature range from -40°C to +40°C ensures reliability in various environmental conditions.
• Connection flexibility: The ability to connect flexible (1.5 - 6 mm²) and rigid (1.5 - 6 mm²) wires ensures compatibility with different types of cabling.
