PRODUCT DESCRIPTION

It is very difficult to optimize the dead time due to the great diversity of load on a system. However, it is possible to study each type of load separately and thereby be able to define a typical dead time.

Description:

Hand Reset Melting Alloy

Application

Hand reset melting alloy overload relays use a 

eutectic alloy solder which responds to the heat 

produced in a heater element by the motor 

current. When tripped, the overload relay may be 

reset manually after allowing a few minutes for the 

motor and relay to cool and the solder to solidify.

Square D’s one-piece thermal unit construction 

will provide overload protection for the majority of 

motors. Repeated tripping does not affect the 

original calibration. Melting alloy thermal units are 

available in three designs: standard trip, slow trip 

and quick trip.

Standard Trip (Class 20)–All standard trip thermal 

units provide trip characteristics for normal motor 

acceleration up to approximately 7 seconds on a 

full voltage start. 

Slow Trip (Class 30) – Type SB thermal units 

provide trip characteristics for motor acceleration 

up to approximately 12 seconds on a full voltage 

start. The motor should be suitable for extended 

starting periods.

Quick Trip (Class 10) – Type FB thermal units are 

used to protect hermetically sealed, submersible 

pump and other motors which can endure locked 

rotor current for a very short time, or motors which 

have a low ratio of locked rotor to full load current.

Replaceable Contacts – The contact modules of 

Type S, F and G overload relays are replaceable. 

Refer to Page 13.

Alarm Contacts – Contact modules with one N.O. 

and one N.C. contact are available for Type S, F, 

an G overload relays. For Type S, specify Form 

Y34-2; for Types F and G, specify Form Y34. 

Y34-2 indicates a four terminal isolated contact 

module and Y34 indicates a three terminal module 

with a common terminal between the N.O. and 

N.C. contacts. Refer to Page 13.

Contact Ratings – For the overload relay control 

circuit contact ratings refer to Page 13.
