Electronic Overload Relays
The 3RB2 range of Solid State Electronic overloads can be connected directly to Siemens SIRIUS contactors to provide accurate motor overload protection with enhanced single phase sensitivity,Application: Protection of 3 phase AC motors in sinusoidal 50/60Hz network. These relays are not suitable for the protection of single phase or DC loads,Select according to motor full load current and contactor frame size e,g. S00
