Motor Starter Protector MSP, Contactor/Starter Combination
Frame Size, Starter:
4.5 - 6.3
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. 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 32A. 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 V. The 3RT2 contactor is particularly suitable for extremely complex switching tasks requiring the greatest endurance.
Operating Temperature: -20 to 60 deg C (-4 to 140 deg F), IEC IP20, Contactor Auxiliary Contacts: 1 NO, Screw Connection for Screw Mounting or 35 mm Rail-Mounting
