Electromagnetic contactor C294

DChigh-voltage

The Schaltbau C294 contactor is a compact, two-pole DC contactor with a rated insulation voltage of 1500 V, which was developed for use in transport technology and can withstand extreme ambient temperatures. C294 A Compact double pole DC contactor with blowout magnets, electric arc arcing chamber and quenching plates. S870 snap-action switch as an optional auxiliary contact. The double pole DC contactor C294 can switch on and carry high currents. It was designed for switching frequently under load. Thanks to an optimised design, the C294 achieves a rated insulation voltage of 1,500 volts in a compact design. In order to control switching arcs safely, design A possesses blowout magnets, arcing chambers and quenching plates. Using an auxiliary switch, the contact state can be reported to the higher-level control system. Developed for use in transport technology, the C294 can be used in a wide range of DC applications – even in extreme temperatures of minus 40 to plus 70 degrees Celsius. This is an especially reliable piece of switchgear with a longer-than-average electrical service life. Features 1,500 volt rated insulation voltage in a compact design Electric arcs managed using blowout magnets, arcing chambers and quenching plates Optional auxiliary contact with snap-action switch Electrical service life: 600,000 switching operations Ambient temperature: –40°C up to +70°C Main and pre-charging contactor in DC applications up to 1,500 volts
