The new Contactron hybrid motor starters from Phoenix Contact are the space saving alternative to mechanical contactor circuits. They offer long service life and up to four functions: clockwise contactor, counter-clockwise contactor, motor protection relay, and emergency stop. A range of compact switchgear for motors up to 4kW is available from the simple 'one-in-one' direct starter up to the 'four-in-one' reversing starter with motor protection and emergency stop.
The 22.5mm wide devices are available in the three power classes 0.6A, 2.4A, and 9A — with input voltages of 24Vdc or 120/230Vac. The new 0.6A power class is suitable for motors up to 0.18kW.
The hybrid technology a microprocessor-controlled combination of rugged relay technology with wear-free semiconductor technology reduces the load on the relay contacts, facilitates low-wear switching, and therefore extends the service life of these devices by a factor of ten when compared with a standard, purely mechanical device.
