Description
The TeSys Deca LRD thermal overload relay is designed for reliable protection of 3-phase motors operating at up to 7.5 kW at 400 V. With a thermal adjustment range of 12 to 18 A and a tripping class of 10A, it offers efficient protection against overload, phase failure, and current imbalance.
This differential relay features 1 NO + 1 NC auxiliary contacts for signalling, a transparent protective cover with lockable sealing, and built-in manual or automatic reset selection. It also includes a test selector for simulating a trip, a flag indicator for quick status checks, and a stop button. The relay connects directly to the terminals of LC1D18 to LC1D38 contactors using screw clamp terminals, or can be mounted separately using the LAD7B106 terminal block (sold separately).
Suitable for AC and DC networks, the device complies with multiple international standards including IEC, UL, CSA, CCC, EAC, ATEX, and Marine certifications. It is also RoHS and REACH compliant under Schneider Electric’s Green Premium label.
