JANITZA 1503351 KUW2/40 Cable Conversion Current Transformer 200/1A, Class 1, 2.5 VA, 40mm Opening

The JANITZA KUW2/40 cable conversion current transformer (model 1503351) transforms high primary currents into a safe, standardized 1 A secondary signal without interrupting the existing cable. Its split-core design with a 40 mm cable opening allows retrofit installation around already-installed conductors, making it a practical choice for energy monitoring upgrades in existing distribution boards.

Highlights

• 200 A primary to 1 A secondary ratio for precise current measurement
• Class 1 accuracy with 2.5 VA rated burden
• 40 mm cable opening for retrofit on existing conductors
• FS5 overcurrent limit factor for reliable performance under overload
• Operating voltage up to 0.72 kV, suitable for low-voltage networks

In daily use

The KUW2/40 mounts quickly with cable ties or screws and connects via M3 screw terminals. Its self-extinguishing polycarbonate housing ensures durability, and the compact design fits tight spaces. The transformer operates across -25°C to +50°C, making it suitable for a wide range of indoor environments.
