General
Full-voltage contactors
Class 8502 Type S magnetic contactors are used to switch heating loads,
capacitors, transformers and electric motors where overload protection is provided
separately. Class 8502 contactors are available in NEMA Sizes 00 to 7. Type S
contactors are designed for operation up to a 600 V, 50 to 60 Hz.
Full-voltage starters
Class 8536 Type S magnetic starters are used for full-voltage starting and stopping
of a.c. squirrel-cage motors. Motor overload protection is provided via solid-state
overload relays. Type S starters are available in NEMA Sizes 00 to 7 and are
designed for operation up to a 600 V, 50 to 60 Hz.
Full-voltage reversing contactors
Class 8702 Type S reversing magnetic contactors are used for starting, stopping and
reversing a.c. motors where overload protection is provided separately. Class 8702
reversing contactors consist of two Class 8502 contactors mechanically and
electrically interlocked. Open-type devices, Sizes 0 to 5, are available in either
horizontal or vertical arrangements. Sizes 00, 6 and 7 are available as horizontal
only. Enclosed devices Size 00 to 7 use horizontally arranged components. Type S
reversing contactors are designed for operation up to a 600 V, 50 to 60 Hz.
Full-voltage reversing starters
Class 8736 Type S reversing magnetic starters are used for full-voltage starting,
stopping and reversing of a.c. squirrel-cage motors. Class 8736 starters consist of
one Class 8502 contactor and one Class 8536 starter mechanically and electrically
interlocked. Open-type devices, Sizes 0 to 5, are available in either horizontal or
vertical arrangements. Sizes 00, 6 and 7 are available as horizontal only. Enclosed
devices use horizontally arranged components. Type S starters are designed for
operation up to a 600 V, 50 to 60 Hz.
