Description
The Trane RLY03742 N/O Power Relay 24-240V is an electromechanical switching component that controls electrical circuits within HVAC systems. It responds to a low-voltage control signal to open or close contacts, allowing higher-voltage current to flow to components such as compressors and fan motors. With a double-pole, single-throw configuration and normally open contacts, it manages simultaneous circuit switching. Positioned within the systems control panel or electrical section, it supports coordinated operation, enabling accurate control of heating and cooling equipment.
