Siemens 3RU21161FB0 Thermal Overload Relay 3.5 to 5.0 Amp Class 10 Size S00 Contactor Mounting Manual Automatic Reset Screw Terminal

SIRIUS 3RU Thermal Overload Relays The 3RU thermal overload relays up to 100 A are designed for current-dependent protection of applications with normal start-up conditions against impermissibly high rises in temperature as a result of overload or phase failure. The 3RU thermal overload relays are electrically and mechanically optimised to the 3RT contactors such that, in addition to individual mounting, they can also be directly mounted onto the contactors to save space.
