FOR CURRENT INFORMATION
Isolated Alarm Contacts For Melting Alloy Overload Relays
Isolated overload relay alarm contacts are available factory installed or in kit form for field installation in Type S,
NEMA Size 00–6a starters and Class 9065 Types M and S melting alloy overload relays. Type S, NEMA Size 7,
utilizes a solid state overload relay which has isolated alarm contacts as a standard feature. The alarm contacts
allow the starter to be used in applications which require isolated contacts, such as inputs to a computer.
Class 9999 Types SO4 and SO5 modules are interchangeable with the standard module (Class 9998 Type SO1)
and may be installed on starters already in service. The case is made of clear plastic (polycarbonate) to allow for
visual inspection of contacts.

Compression Lugs
A Class 9999 Type AL hardware kit is required to install Square D Versa-Crimp® compression lugs on Class 8903
Type S, 100–800 A lighting contactors. The lugs are suitable for both copper and aluminum wire.
One VCEL lug is required for each line or load terminal. Each Class 9999 Type AL hardware kit includes mounting
hardware for 3 terminals, line or load side.
EXAMPLE: To install compression lugs on a 300 A 3-Pole device, line and load sides, order six VCEL06012H1 lugs
and two Class 9999 Type AL11 hardware kits.
