MICROTEMP®
thermal cutoffs are available in a range of temperatures and electrical
ratings to meet your application requirements (See figure 4). There
are four primary types of thermal cutoffs available including three
global agency rated series plus a high precision series with special
quality certification. Standard dimensions of each TCO series are
shown in figure 3 below.
G4 Series
- Rated for continuous operating currents up to 10 amps@25OVAC (l5amps@
120 VAC), the G4 Series MICROTEMP® TCO is the industry standard
for over temperature protection. The G4 Series is applied to millions
of appliances and personal care products each year providing reliable
back-up protectton for tern peratu re controlling thermostats and
other over temperature conditions. The G4 Series is also widely
applied in office machines, portable heaters and industrial equipment
as a thermal safeguard. In the event of the thermostat end of life
condition or other over temperature condition, the MICROTEMP TCO
protects against potentially hazardous over-heating by interrupting
the electrical current in the product.
G5 Series
- Designed for special high current applications, the G5 Series
MICROTEMP® TCO is rated for operating currents up to 16 amps @250
VAC (25 amps @ 120 VAC). Similar in appearance to the G4 Series,
the G5 Series has a different internal construction capable of interrupting
higher currents. G5 Series TCOs are found in electric heaters and
other higher current devices requiring overtemperature protection.
G7 Series
- The G7 Series MICROTEMP TCO is designed to satisfy applications
requiring lower current interrupt capability. The G7 Series thermal
cutoff is approximately 30% smaller than the G4 and G5 Series and
can satisfy the smaller size requirements of transformers, motors
and electronic circuit applications.
Y1 Series
- The Yl Series MICROTEMP TCO is built to rigid manufactu ring processes
and x-ray inspection specifications. The Yl Series is used in aircraft
applications such as fuel booster pump motors and heaters. Please
contact a Therm-O-Disc sales engineer for further information on
the Yl Series TCO.
