1102C-COB93

The Allen-Bradley 1102C-COB93 contactor is a 400 Amps-rated vacuum contactor unit. It has a voltage rating of 1500 Volts AC. This 3-phase contactor device supports different application demands. It can be used in mining, chemical, cement, and pump applications. With different loads, the contactor supports an operating frequency of 50 to 60 Hertz. The contactor has an open type of enclosure and it should be protected against water sprays and splashes. The contactor should never be exposed to sources of EMC noise and high heat. The 1102C-COB93 contactor is certified with the UL 508, CSA standards. It has a making and breaking current capacity of 3200 Amps. The dielectric strength of the vacuum contactor unit is 6 kilovolts with the interrupter gap. The interrupting current rating of the unit is 4.6 kiloamps.

The Allen-Bradley 1102C-COB93 contactor is made out of high-quality material and it has a mechanical lifespan of about 1,000,000 operations and a switching frequency of 600 hours maximum with 6 seconds at a full cycle. The operating temperature should be set between -54 and 71 degrees Celsius, and this contactor can operate properly at up to an altitude of 2000 meters. The 1102C-COB93 contactor comes with a current rating of 3.2 Amps and a chop current of 0.9 Amps. The front side of the vacuum contactor comes with an on/off switch along with a label that shows information like the ratings of the contactor. It is a Series A device that can easily handle Design E motors and circuits capable of delivering not more than 18 kiloamps at 1500 Volts AC. The top and bottom contacts can be easily connected using copper wire rated for 75 degrees Celsius.
