B84742A*R725 line filters for TH35 DIN-rail mounting

Line filter for TH35 DIN-rail mounting

The single-phase, 2-line EMC filters from TDK Electronics AG can be mounted onto a TH35 DIN rail. These small filters serve AC and DC applications up to 250V and rated currents from 6A to 30A.

The conductors are fastened with M4 screws, and the screw connection is equipped with touch protection. The insertion loss is very high and depends on frequency and model. Leakage currents are very low at less than 2mA, which prevents unintentional tripping of RCDs. All types of this product family are UL-approved and specified for a rated temperature of up to 55 °C.

 

For short periods, these filters can handle higher currents; 150% of the rated current is allowed for 3 minutes per hour and even 250% for 30 seconds per hour. This is particularly useful in drive applications when starting electric motors.
