Cutler Hammer-Eaton C440A1A045SDD C440 Elec.Overload Relay
The Cutler-Hammer Eaton C440A1A045SDD C440 is an electronic overload relay that is specifically developed to protect HVAC system motors against electrical overloads. It operates by continuously observing the motor's current flow. The circuit breaker is immediately tripped by the relay, which stops the current flow, if the current exceeds a predefined safe limit for a specified period of time. This safety precaution aids in avoiding electrical fires, motor burnout, and damage to other equipment. The electrical current passing through the motor is continuously monitored by the C440 relay.Applications for the C440 relay in HVAC systems include ventilation systems, heat pumps, and air conditioners. The C440 relay enhances the longevity, operational effectiveness, and overall system reliability of these systems by protecting the motors.
