Schneider Electric LRD32 Thermal Overload Relay
Schneider Electric LRD32 Thermal Overload Relay
Product Description:
- A thermal overload relay is a protective device used to protect electric motors and other equipment from overheating due to excessive current.
- It works by monitoring the current flowing through a motor and reacting when the current exceeds a safe limit for a prolonged period, preventing damage to the motor windings.
- LRD thermal overload relay, 32A/690V, thermal setting range 23-32A, tripping class 10A, for protection of 3-phase motors 15kW@400V.
- Differential device with phase failure and load unbalance detection. Connection by screw clamp terminals, it connects directly to the bottom terminals of 3-pole contactors LC1D25-D38.
- The Schneider Electric LRD32 Thermal Overload Relay is a high-performance motor protection device designed to safeguard electric motors, industrial equipment, and machinery from overload, phase failure, and electrical faults.
- Engineered with precision thermal sensing technology, the LRD32 relay ensures reliable motor protection, reduces downtime, and prolongs motor lifespan.
- This LRD32 Thermal Overload Relay features adjustable current settings, quick response time, and durable construction, making it ideal for industrial control panels, motor starters, and automation systems. Its robust design ensures accurate overload detection, protecting motors from excessive current and preventing equipment damage.
