Series CA7 Contactors
Controls Motors As Little as Reduces Mechanically
to 60HP (@460/575V) 45mm Wide Panel Space Linked Auxiliaries
Coil terminals are field-reversible!
Mount a motor circuit controller on top or
an overload relay on bottom
Dual-terminal technology maximizes
wiring options and termination reliability
Auxiliary contacts may be mounted
on front and/or sides of contactor
9-85A range covers more than 90%
of all industrial applications
All CA7 contactors are designed, tested
and can be selected for Type 1 and
Type 2 Coordination
Auxiliary contacts are “mechanically
linked” with CA7’s main contacts –
a requirement in safety circuits
Protects against manual operation
and accidental contact with live parts
Dimensionally compatible with
KT7 motor circuit controller and
CEP7 electronic overload relay
Compact dimensions mean less
panel space and lower cost
Universal accessories fit all CA7
contactors – leaving you with less
inventory and more flexibility!
As little as 45mm (1-3/4") wide
Label your contactor for easy identification
IEC design provides a more precise fit
to your application – save money by
buying only what you need
Compact dimensions with maximum performance! Our CA7
contactors control motors up to 60HP, in frame sizes ranging
from 45mm (1-3/4") to a maximum of 72mm (2-3/4") wide.
Because of its modular design, CA7 is flexible and easy to use.
All CA7 contactors use the same accessories, reducing the need
to stock additional inventory. They are also mechanically and
electrically compatible with Sprecher + Schuh’s CEP7 electronic
overload relay and KT7 motor circuit controller. This provides
easy, clean installation for a variety of motor starter applications.
Whether part of a system or for individual use, the CA7 is the
right contactor for the job.

Series CA7 Contactors
Dual terminal technology provides
additional wiring options,
as well as increased reliability and
a faster wiring process.
Save space, save money
The CA7 contactor series includes ten contactors within four frame
sizes. The two smallest sizes house capacities up to 25HP (@460V)
and 30HP (@575V). They measure only 45mm (1-3/4") in width!
Even the largest of the contactors – the CA7-85, controlling motors
to 60HP – measures only 72mm (2-3/4") wide. The space you save
with CA7 translates to smaller panels and lower cost.
Maximum flexibility
The CA7 contactor is designed for
ultimate flexibility. Coil terminals can
be supplied on the top or bottom, and
are field-reversible to suit individual
wiring needs. Auxiliary contacts can
be mounted on the top and sides, for
the most efficient use of panel space.
In reversing applications where space
may be tight, the mechanical interlock
has a built-in auxiliary to save room.
Field-reversible coil terminals
provide additional flexibility
Dual wiring terminals speed installation
State-of-the-art technology
CA7 contactors utilize the latest design technology. Combined
with Sprecher + Schuh’s CEP7 solid state electronic overload
relay, the CA7 becomes the most accurate and reliable motor
starter available. Mechanically linked contacts provide safety for
all applications. In addition, snap-on electronic timers and a PLC
interface are also available.
Modular design
The CA7 contactor series includes
universal accessories to fit
every frame size. This provides
incredible flexibility, and eliminates
the need to purchase
size-specific components.
Because of their modular design,
CA7 contactors are easily joined
to form complete starter combinations. The CA7 is specially
designed for electrical and mechanical compatibility with our
overload and motor circuit controllers.
