Description
Schneider Electric LRD02 TeSys LRD Thermal Overload Relay, 0.25 A/690 V, Thermal Setting Range 0.16-0.25 A, Trip Class 10 A, for Protection of 3 Phase Motors 0.06 kW at 400 V. Differential Device with phase failure (loss). It has a thermal adjustment wheel, manual-automatic reset selector, test selector to simulate tripping, reset and stop buttons, flag indicator, and 2 auxiliary contacts 1NO+1NC for error signaling. The settings are protected by a transparent lid that can be sealed shut.
The connection is made using screw terminals and connects directly to the lower terminals of the LC1D09-D38 three-pole contactors. DIN rail or screw mounting, separate from the contactor, using a LAD7B106 terminal block (ordered separately). Certified to multiple standards (IEC, UL, CSA, CCC, EAC, ATEX, Marine), Green Premium compliant (RoHs/Reach).
Features
- Range of TeSys thermal relays for motor protection.
- Compensated, with automatic or manual reset and trip indication.
- TeSys three-pole thermal protection relays
- For mounting on LC1 type contactors of the TeSys series.
- Without direct mounting on old contactors (add panel) for Ref. LRD01 to LRD35.
- It is possible to use a pre-wiring kit and a DIN rail mounting bracket.
- Equipped with test function.
