5 RAMO5 motor starter5.2 Features122 Rapid Link 5 · RAMO5 · RASP5 05/20 MN034004EN www.eaton.com5.2 FeaturesRAMO5 (Rapid Link motor control unit) is an electronic motor starter fordirect start-up of three-phase motors up to 6.6 A (≙ 3 kW at 400 V).RAMO5 uses thyristors and relays for switching in the power circuit.This makes it possible for the units to have a lifespan of more than 10 millionswitching cycles.RAMO5 is available in two versions with respect to the direction of rotation:• RAMO5-D… = DOL starter for one direction of rotation• RAMO-W… = Reversing starter for two directions of rotation (FWD, REV)After run-up, the speed of the controlled motor is constant and is determinedby the frequency of the supply voltage (power bus, 50/60 Hz). The three-phase motor protection allows protected operation of three-phase motors inthe range from 0.3 A (≙ 90 W at 400 V) to 6.6 A (≙ 3 kW at 400 V).This enables the so-called thermistor motor protection to be implemented inconjunction with the integrated thermistor monitoring.The built-in transistor switch allows actuation of spring-loaded brakes withDC air solenoid valve. A controlled supply voltage of 180 V AC, 230 V AC or400 V AC is output for the brake rectifier (￫ Figure 64, page 107). DANGEROpen only in voltage-free state!
