Overview

Details for LR3D3555

LR3D3555 Class 20 Overload Relay: Schneider Electric (Square D)The LR3D3555 is a 40 Amp class 20 thermal overload relay produced by Schneider Electric (Square D). Designed for motor protection, this reliable relay offers precise overload protection for motors rated up to 15 horsepower. Key Features: Compact Design: LR3D3555 is remarkably compact, occupying minimal panel space and simplifying installation. Manual Reset: The manual reset button allows for quick and easy resetting of the relay after a trip, minimizing downtime. Trip-Free Mechanism: Even when the reset button is held in, the relay will trip if an overload occurs, ensuring superior protection. Adjustable Trip Setting: Trip current can be easily adjusted to match the specific motor requirements, ensuring optimal protection. Applications: The LR3D3555 overload relay finds applications in various industrial settings, including: Conveyor systems Pumping systems Manufacturing machinery HVAC equipment Choose our HVAC supply store for the best prices and fast shipping on your electrical supplies! LR3D3555 is a TeSys LRD thermal overload relay from Schneider Electric to be used with a TeSys D contactor. It protects motors 18.5kW@400V thanks to a thermal range 30-40A , a tripping class 20, for use with unbalanced loads. LR3D3555 is a TeSys LRD thermal overload relay from Schneider Electric for direct mounting on TeSys D contactors. With a thermal setting range 30-40A and tripping class 20, it protects unbalanced loads and motors 18.5kW@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, for use with unbalanced loads (non differential). Direct mounting on the bottom terminals of a Tesys contactor LC1D80 and D95 to form a compact starter. Light and compact, 70mm wide. Temperature compensated for a good accuracy of the protection. 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 (LAD7B, LAD96) and remote control devices (LAD703, LA7D03).
