Series CA5 Contactors

1 Series C5 Contactors The contactor for heavy industrial applications from 500HP to 900HP DISCONTINUED This series is being replaced by the C9 Series of contactors C5 Series contactors provide large horsepower performance with a design that is up to 40% smaller than traditional contactors of this rating. The entire line is modularly designed for easy inspection, contact replacement and coil change out. ll maintenance can be performed from the front so that mounting can be accomplished with no wasted space on the sides. The contactor for large horsepower applications The C5 series consists of four contactors in two frame sizes covering motors from 500 to 900 HP (at 460V/575V). This line is well suited for heavy industrial applications utilizing large machinery and equipment such as rock quarries and mines, or for any large horsepower application where a rugged and dependable contactor is needed. Specially designed shockfree contact system characteristic of contactors in this size class is to transmit intense impact forces during operation. This is caused by the heavy magnetic armatures of the core, which can cause contact bounce. C5 contactors, however, are designed so that the operating planes of the electromagnets and the contacts are opposed to each other by Direction of electromagnets (coil armature) Direction of main contacts 90. This results in a bounce-free contact system, increasing the contactor s mechanical life and raising contact reliability. Rugged and reliable massive steel framework supporting the magnet system ensures high stability in all applications. Low-wear materials for bearings and sliding surfaces, as well as generously dimensioned magnet-pole faces result in above average mechanical life with a minimum of maintenance. Despite their rugged construction, overall contactor weight has been reduced considerably permitting simpler panel construction and easier assembly. 280mm ( 11 ) mm ( 13 3/16 )

2 Unique coil feeder group offers many advantages C5-700 and 860 contactors are equipped with a special feeder group for the coil that accommodates C control voltages of 50 or 60Hz, and a wide range of DC voltages. djustable auxiliary contacts C5 contactors can be equipped with a maximum of four NO and four NC auxiliary contacts. In addition, the closing time of the auxiliary contacts (on C5-700 & 860 contactors) can be adjusted to meet individual control requirements. Two choices for interlocking reversing contactors Unique to the C5 range is the ability to mechanically interlock reversing contactors in either a horizontal or vertical orientation. This feature allows maximum flexibility when laying out panels. This coil arrangement eliminates noise and provides very low pickup and hold-in current. In addition, the dropout time of the coil can be adjusted within one of three ranges. Normal Drop (150 to 200ms): for prompt reaction of contactor to a breaking command (factory setting). Delayed Drop (0.5 to 1s): where it is necessary for the contactor to be immune to short power supply interruptions or uncertain control devices. Fast Drop (about 20ms): for safety applications where instant dropout is required. Modular, convenient design The C5 line is modularly designed for easy inspection, coil change and contact replacement. Maintenance can be performed from the front so that mounting requires no additional space. Even with the installation of mechanical interlocks and auxiliary contact blocks, the units can be flush mounted side by side, saving panel space. dd-on fourth pole In many applications, the neutral also needs to be switched. ll C5 contactors can be fitted with a 4th pole on either the left or right side of the contactor. This switched neutral is available as an accessory that can easily be installed in the field.

6 ll C5 contactor coils are made up of two parts; the Coil Pair and Feeder Group. When ordering replacement parts, usually assume the Coil Pair must be replaced. If control voltage changes, user must order Coil Pair and matching Feeder Group. Even though all C5 coils are designed for C input (DC input also available for C contactors), they are operated by a DC voltage supplied from a feeder group. lways order Renewal Parts by the Coil Code matched to the actual control voltage available to the contactor.
