Compressor Circuit Breakers
Every fixed speed compressor is protected by a circuit
breaker. If replacement is necessary, please refer to the
circuit breaker nameplate to identify the part number and
manufacturer. Contact the circuit breaker manufacturer to
locate the datasheet for the circuit breaker to find the "must
hold / must trip" values.
Supply and Relief/Return Fan Overloads
When the VFD bypass option is selected, each supply and
relief/return fan is protected by a motor overload when in
VFD bypass mode. On 60-75T units with dual DDP supply
fan motors (with or without VFD bypass option), each
supply fan motor is protected by a motor overload in both
standard operation and VFD bypass mode. The motor
overloads are factory set to the motor FLA value and
should not be adjusted. If the current to the motor exceeds
the overload dial setting value, the overload relay auxiliary
contacts will trip and interrupt the control signal to the run
and bypass contactor coils. This will remove power from
the fan motor and stop operation.
