TeSys LRD thermal overload relays - 30...38 A - class 10A
Formerly named TeSys LRD. Thermal relays, coordinated with TeSys Deca contactors and circuit-breakers, to protect from overloads motors up to 150 A (75 kW / 400 V)
TeSys LRD thermal overload relay, 38A/690V, thermal setting range 30-38A, tripping class 10A, for protection of 3-phase motors 18.5kW@400V. Differential device with phase failure (loss). 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 LC1D32-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).
