Siemens 4EM5005-7CB00 Commutating Choke
Siemens Commutating Choke for Converters - 400V, 18A
The Siemens Commutating Choke (4EM5005-7CB00) is designed for use with converters, helping to smooth current and reduce ripple. It is a single-phase choke with a rated voltage (UN1) of 400V. Key specifications include a maximum continuous current (ITHMAX) of 20A at 50 Hz and an inductive current (ILN) of 18A. The choke has a low leakage inductance (LN) of 2.42 mH and a voltage drop (UK) of 4%. It is rated for ambient temperatures up to 40°C (TA/ISOKL: 40 /B) and has an IP00 protection rating. Terminals are screw/tab connection type, and it complies with EN 61558-2-20 standards.
This commutating choke is essential for protecting converter components and improving the performance of drive systems. It is commonly used in applications requiring filtered power for sensitive electronics, such as in motor control systems, industrial power supplies, and renewable energy converters. Its function is critical in minimizing electrical noise and ensuring stable operation.
