Description
LR2K0307 is a TeSys LRK thermal overload relay from Schneider Electric to be used with a TeSys K contactors. It protects motors 0.55kW@400V thanks to a thermal range 1.2-1.8A, a tripping class 10A and phase unbalance protection. LR2K0307 is a TeSys LRK thermal overload relay from Schneider Electric for direct mounting on TeSys K contactors. With a thermal setting range 1.2-1.8A, a tripping class 10A and phase unbalance detection, it protects motors 0.55kW@400V. It provides manual test & reset buttons, automatic reset, trip auxiliary contact and flag indicator. Available worldwide, it is multi-standards certified (IEC, UL, CSA, CCC, EAC, Marine). Thermal overload protection relay, bimetallic type, with phase unbalance protection (differential). Direct mounting on the bottom terminals of a Tesys contactor LC1K06 to form a compact starter. Light and compact, 45mm wide. Manual control with test & reset buttons, manual / automatic reset selector. Trip signaling with 1NO+1NC auxiliary contacts and trip flag indicator. Can be completed with terminal blocks for separate mounting (LA7K0064).
Features
- Equipped with an adjustable thermal setting dial, this relay provides a precise current adjustment range of 1.20 to 1.80 Amps. This localized adjustment wheel lets maintenance technicians fine-tune the trip threshold to match the exact nameplate FLA of small pumps, fans, or conveyor drives, eliminating nuisance tripping while ensuring strict compliance with Canadian Electrical Code overcurrent protection standards.
- This TeSys K differential thermal overload relay features integrated phase failure sensitivity that monitors current balance across all three phases. If a single-phasing event or a critical phase unbalance occurs, the internal mechanism trips rapidly to cut power to the control circuit, protecting your expensive 3-phase fractional-horsepower motors from catastrophic overheating and premature winding burnout.
- Designed for seamless, plug-and-play mechanical integration, this overload relay clips and bolts directly onto the bottom terminals of the TeSys K miniature contactor series (such as the LC1K or LP1K). This direct-mounting architecture eliminates the need for extra interconnecting wires, reduces labor times, and keeps your overall control assembly footprint remarkably compact on the DIN rail.
- This device comes factory-equipped with 1 NO (Normally Open) and 1 NC (Normally Closed) auxiliary contacts rated for standard industrial control circuits. The NC contact wires directly into your contactor coil loop to drop out power during a fault, while the NO contact simultaneously signals a local pilot light or routes a discrete digital input back to a supervisory PLC for immediate fault diagnosis.
