Schneider Electric LRD332 Thermal Overload Relay
Schneider Electric LRD332 Thermal Overload Relay
Product Description:
- A Thermal Overload Relay is a protective device used in electrical circuits to prevent motors and other equipment from overheating due to excessive current flow.
- It operates based on the principle of thermal expansion, making it a reliable safeguard against prolonged overload conditions.
- Thermal overload relays are an essential component of motor starters and motor control centers.
- These relays are commonly use in applications such as pumps, fans, conveyor systems, and any equipment that involves electric motors.
