Full Voltage Contactors—NEMA Rated

 

Class 8536 / Refer to Catalog 8502CT9701

General Information

Type S magnetic starters are used for full-voltage starting and stopping of AC squirrel cage motors. Motor overload protection is provided via melting alloy type thermal overload relays. Type S starters are available in NEMA Sizes 00 through 7, and are designed for operation at 600 Vac, 50 to 60 Hz.

Solid State Overload Relay Protection (MOTOR LOGIC®)

These ambient insensitive overload relays are available on Sizes 00 through 6 and standard on size 7. They provide phase loss, phase unbalance protection and a power LED indication. To order, add Form H10 (for Class 10), H20 (for Class 20), or H30 (for selectable trip class protection). For more information about MOTOR LOGIC, see pages16-98, 16-112 and 16-113.

3-Pole Polyphase—600 Vac Maximum—50–60 Hz

Note that prices shown do not include thermal units. Devices require 3 thermal units (Sizes 00–6). Standard trip thermal units are $14.30 each. See page 16-129 for selection information.

a	Size 6 and 7 are rated NEMA 4 only, painted sheet steel.

b	Coil voltage code must be specified to order this product. Refer to standard coil voltage codes shown below.

c	24 V coils are not available on Sizes 4–7. On Sizes 00-3, where 24 V coils are available, Form S (separate control) must be specified (i.e., order as 8536SBO2V01S).

d	120 Volt Polyphase contactors are wired for separate control. Form S (separate control) must be specified (i.e., order as 8536SCO2V02S).

For voltage codes used with control transformers, see page 16-111. Form S (separate control) is used when a separate source of power is available for the control (coil) voltage. Form S is supplied at no charge.

For How to Order Information, see page 16-11.
