SIRIUS 3RA2 Fuseless Load Feeder Starter, 24 VDC Coil, 3 Poles, IP20 Enclosure

The 3RA2 fuseless load feeders consist of the 3RV2 motor starter protector and the 3RT2 electromechanical contactor. The devices are electrically and mechanically connected using preassembled assembly kits (link modules, wiring kits and standard mounting rail or busbar adapters). Around 500 preassembled 3RA2 combinations of these innovative 3RT2 controls and 3RV2 protection equipment can be ordered for direct on line and reversing starting of standard three phase motors up to 32 A (approximately 15 kW/400 VAC). In the 3RA2 load feeder, the 3RV2 motor starter protector is responsible for overload and short-circuit protection. Back up protective devices, such as melting fuses or limiters, are superfluous here, as the motor starter protector is short circuit proof up to 150 kA at 400 VAC.
