General Electric AC Non-Reversing IEC Contactors, C-2000 Series. Better performance in high vibration applications; wind, marine, transportation. Increased contact pressure reduces resistance per phase and thermal load. Noise reduction even in hard environments with dust and corrosion. No dimensional changes facilitates the exchange of products. Wider temperature range for operation: 40 to +70 Degrees C. Use at elevations up to 3000 m without derating. Transient voltage suppressor built-in.
