Schneider Electric LRD12 Thermal overload relay
Schneider Electric LRD12 Thermal overload relay
- Thermal overload relays are an essential component of motor starters and motor control centers. They help prevent motor damage, reduce energy waste, and enhance safety by protecting against excessive heating and the risk of fires caused by overloaded or faulty motors. These relays are commonly use in applications such as pumps, fans, conveyor systems, and any equipment that involves electric motors.
