Product Description
The SIEMENS 3RU2126-1EB0 thermal overload relay is designed to provide current-dependent protection for loads with normal starting against impermissibly high temperature rises due to overload or phase failure. This rise heats up the bimetal strips inside the device which then bend and as a result trigger the auxiliary contacts. The relay is reset manually or automatically after a recovery time has elapsed.
- Suitable for operation with frequency converters.
- Contact arrangement: 1 N/C + 1 N/O
- Manual and Auto Reset
