Datasheet | Spring-Applied Brakes - INTORQ BFK458
The document provides technical specifications for the spring-applied brakes models BFK457 and BFK458. These specifications include protection ratings based on the DIN EN 60529 and DIN EN 60034-5 standards, which relate to protection by housing and rotating electric machines, respectively.
Protection Ratings
The protection ratings for the brakes vary depending on their mounting position and additional components:
- BFK458 without additional components: IP00 when mounted on the machine’s free side frame.
- BFK458 with seal and shaft seal: IP54 when mounted on the machine’s free side frame.
- BFK457 without additional components: IP00 when mounted on the machine’s free side frame.
- All models achieve IP55 when mounted under the fan cowl without manual release.
- When mounted under the fan cowl with manual release, BFK458 and BFK457 have a protection rating of IP22.
Installation Considerations
When the brakes are mounted under the fan cowl, they must be protected from water splashes by the fan and cowl. The protection is limited if there is a slot for manual release. In damp conditions, it is crucial to ensure proper water drainage and ventilation to maintain the brakes' functionality.
Catalog excerpts
Technical Specifications Protection ratings for spring-applied brakes BFK457 and BFK458 The protection classes listed in the table were classified under the test conditions stipulated by the DIN EN 60529 standard (protection by housing) and the DIN EN 60034-5 standard (rotating electric machines). usually restricted when it has a slot for manual release. Generally, if the brake is used in damp conditions, it is necessary to ensure there is water drainage and ventilation. When the brake is mounted under the fan cowl, it is necessary for the brake to be protected by the fan and the cowl from splashes of water. This protection by the cowl is Mounting position BFK458 without additional components BFK458 with seal and shaft seal BFK457 without additional components On the machine’s free side frame Under the fan cowl without manual release Under the fan cowl with manual release Kendrion INTORQ GmbH Wülmser Weg 5 31855 Aerzen Germany T +49 5154 70534-222 [email protected] www.kendrion.com © KENDRION 04.10.2021
