4. DT and DTP thermostats are single pole
single throw with two sliver contacts which
prevent
arching, resonance and clicking sound. Snap
action switch assembly guarantees full
pressure
on the contacts and close the circuits on rise
of temperature
5. Overload protectors are used in single phase
(fraction horse power) hermetically
sealed compressors to protect motor from
burning.
6. It provides positive protection against low
voltage, improper current supply and
excessive overload.
7. These are used to start and protect the motor
8. Starting relay circuit is designed to cut in the
start winding when motor is to start and cut
out
when the motor has gained sufficient speed
to run without start winding.
9. Principally designed for starting capacitor
start and capacitor run motor of hermetic
compressors.
11. The purpose of the SMR relay is to cut in the
start winding when the motor is to start and
cut out
when the motor has gained sufficient speed.
12. The purpose of the PTCR-relay is to allow
required current to pass through the start
winding of motor.
Once the motor has gained sufficient speed
the PTCR restricts the flow of further current
to the start winding
