Siemens 4EU2452-2UA00-0AA0 Current Transformer

Siemens 4EU2452-2UA00-0AA0 is a three-phase line reactor (Netzdrossel) designed for frequency converters, configured for 480 V input (Un1) and 60 Hz operation. It supports a line current (I LN) of 144 A with a maximum rating (Ith max) of 160 A and provides a per‑phase inductance of 0.088 mH. The unit exhibits a rated voltage drop (Uk) of 2% at rated current and carries a thermal/insulation class of 40/H, with IP00 protection and flat‑type connections for the main current circuit. Its physical footprint is about 225 mm wide, 210 mm high, and 147 mm deep, making it suitable for installation in drive control cabinets and motor control applications that employ frequency converters. The product is listed as a three‑phase 480 V line reactor intended to be used in conjunction with Siemens frequency converters, aligning with the 4EU2452 family and providing robust current handling for demanding drive environments.
