Thermal Overload Relays – NEMA Rated
Application Data
Remote Reset Module
The Remote Reset Module can be easily field installed on solid state overload relays. This module will
allow the overload relay to be reset from a remote location.
4 – 20 ma DC Communication Module
This module provides 4 - 20 madc output proportional to the percentage of current flowing to the motor,
according to the trip current adjustment setting. This feature works only on 9065 SF and ST overload relays.
Contact Units for Melting Alloy Type Overload Relays
One normally closed contact, Class 9998 Type SO1, is provided in each overload relay block on Type S
starters Sizes 00-4 and Size 6. On the Type S Size 5, a normally closed contact is provided with each of the
three overload relay blocks. The Class 9998 Type SO1 contact unit listed below is provided as standard in
each Class 9065 Type M melting alloy overload relay. Contact modules can be easily replaced and are
identified in the table below. Isolated overload relay alarm circuit contacts are available as an optional feature.
A pilot light or alarm bell can be wired in series with this contact to indicate that the overload relay has tripped.
For further information on isolated alarm contacts refer to Class 9999 Types SO4 and SO5.
Melting Alloy Overload Relay Jumper Strap Kits
Jumper strap kits are for use on three-phase manual or magnetic starters with melting alloy overload
relays only, where a three-phase starter is used to control a single-phase motor. These kits will include
two jumper straps, a wiring diagram showing how to wire a three-phase starter to control a single-phase
motor, and single-phase (one thermal unit) selection tables.
