Schneider Electric LR2K Thermal Overload Relay 1NO + 1NC, 0.23 → 0.36 A F.L.C, 360 mA Contact Rating, 100 W, 250

Schneider Electrics K thermal overload relays are adjustable from 0.11 to 11.5 A, they have been predominantly designed for use in applications that require motor protection.

This range of mini thermal overload relays feature compensated and phase failure sensitivity, the range also offers manual and automatic reset. Each overload relay has 3-poles and screw clamp terminals.

Phase failure sensitive
Test Button
Trip-Fault Indication
Manual or automatic reset facility
Temp. compensated trip -20 to +55°C

• The majority of the time is to protect a motor
• To detect both overload conditions and fault conditions to then announce trip command for a protective device
• To deactivate a device whenever it pulls high current
• Sometimes developed into microprocessor systems and solid-state electronics

LR2K0303 is a TeSys LRK thermal overload relay from Schneider Electric to be used with a TeSys K contactors. It protects motors 0.06-0.09kW@400V thanks to a thermal range 0.23-0.36A, a tripping class 10A and phase unbalance protection. LR2K0303 is a TeSys LRK thermal overload relay from Schneider Electric for direct mounting on TeSys K contactors. With a thermal setting range 0.23-0.36A, a tripping class 10A and phase unbalance detection, it protects motors 0.06-0.09kW@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) and Green Premium compliant (RoHs/Reach). 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).
