The Schneider Electric TeSys LR2 K series represents a pinnacle of engineering excellence in the realm of motor protection. Specifically designed for seamless integration with the TeSys K range of miniature contactors, these thermal overload relays provide a robust, reliable, and space-efficient solution for protecting AC circuits and motors against overloads, phase failures, and prolonged stalling.
The TeSys LR2 K is more than just a safety switch; it is a sophisticated electromechanical component engineered for precision. Utilizing advanced bi-metallic thermal sensing technology, the unit monitors current flow with high accuracy.
- Comprehensive Protection: Engineered to safeguard against overload conditions and phase unbalance, ensuring your machinery remains operational and your downtime is minimised.
- Adjustable Current Settings: Featuring a user-friendly dial for current setting adjustment, allowing for precise matching to the Motor Full Load Amps (FLA).
- Trip Class 10A: Provides a standardised response time, tripping within specific parameters to protect standard motor applications without causing nuisance trips during normal start-up surges.
- Manual and Automatic Reset: Offers the flexibility of manual intervention or automated system recovery, selectable via the front-facing toggle to suit your specific industrial protocol.
Designed with the panel builder in mind, the LR2 K series prioritises ease of installation and a compact footprint.
- Direct Mounting: These relays are designed to clip directly onto the underside of LC1K, LP1K, and LC7K contactors, forming a rigid, cohesive motor starter unit without the need for additional wiring or DIN rail space.
- Integrated Auxiliary Contacts: Equipped with 1 NO (Normally Open) + 1 NC (Normally Closed) auxiliary contacts. The NC contact is typically utilised to break the contactor coil circuit, while the NO contact serves as a fault signal for PLCs or pilot lights.
- Finger-Safe Terminals: Incorporating IP20-rated screw clamp terminals, ensuring protection against accidental contact and adhering to stringent UK and international safety standards.
