TeSys LRD thermal overload relays, 1.6...2.5 A, class 10A

TeSys LRD thermal overload relay, 2.5A/690V, thermal setting range 1.6-2.5A, tripping class 10A, for protection of 3-phase motors 0.75kW@400V. Non differential device, it can be used with unbalanced loads. It provides a thermal adjustement dial, a manual-automatic reset selector, a test selector for simulation of a tripping, reset and stop buttons, a flag indicator and 2 auxiliary contacts 1NO+1NC for fault signalling. 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. Mounting on DIN rail or screw fixing, separated from the contactor, with use of a terminal block LAD7B106 (to be ordered separately). Multi standards certified (IEC, UL, CSA, CCC, EAC, ATEX, Marine), Green Premium compliant (RoHs/Reach).
