LRD thermal overload relays – 7…10 A – class 10A
TeSys LRD thermal overload relay, 10A/690V, thermal setting range 7-10A, tripping class 10A, for protection of 3-phase motors 4kW@400V. Differential device with phase failure and load unbalance detection. It provides a thermal adjustment dial, a manual-automatic reset selector, a test selector for the simulation of tripping, reset, and stop buttons, a flag indicator, and 2 auxiliary contacts 1NO+1NC for fault signaling. Settings are protected by a transparent cover lockable by sealing. Connection by screw clamp terminals, it connects directly to the bottom terminals of 3-pole contactors LC1D09-D38.
