| Sprecher+Schuh’s newest
contactor provides big performance in small package |
| The CA7 represents the most modern and
flexible IEC power contactor available today. A wide selection of ten
contactors in four frame sizes covers the entire CA7 horsepower range (up to
60HP @ 460/575V). Six of the contactors are only 45mm wide, an extremely small
footprint for such rugged performance. |
| |
| Type 1 and Type 2
Coordination |
| Whether you are designing motor circuits
for use in North America, Europe or any other part of the world, all CA7
contactors have been designed and tested with respect to Type 1 and Type 2
short circuit coordination. |
| |
| Advanced safety and
reliability features |
| The entire CA7 line features positively
guided contacts, such that if a main power pole welds, adequate clearances
exist (greater than or equal to 0.3mm) to ensure that the auxiliary contacts do
not change state when coil power is removed and the device tries to open. This
is a requirement in safety circuits. |
| |
| Modular accessories are common to all
devices |
| All accessories are interchangeable
among all CA7 contactors and CS7 control relays. This minimizes inventory
requirements and maximizes flexibility. |
| |
| Reversible coil provides total
flexibility |
| When shipped, both coil connections are
normally located at the top of the contactor in preparation for mounting an
overload relay at the bottom. For multi-starter panels, however, the coil can
be reversed. CA7 contactors can either be ordered with the coil reversed or may
be easily reversed in the field. |
| |
| Dual power terminals speed
wiring |
| CA7-30 through 85 contactors are
designed with two power terminals for all three poles. This simplifies power
wiring of interconnected contactors in reversing, reduced voltage and two-speed
applications. Simplified wiring means less labor and less cost. |
| |
| International standards and
approvals |
| All Sprecher + Schuh contactors are
UL-listed and CSA-approved. They also carry the CE mark and meet IEC 9471
requirements. They are approved in virtually every international
market. |
