Schneider Electric (Square D) LRD22L Relay
The Schneider Electric (Square D) LRD22L is a heavy-duty bimetallic thermal overload relay engineered for precise motor protection in demanding industrial and HVACR environments. Designed for seamless integration, this unit features an adjustable amperage range of 17 to 24 Amps and is specifically rated as a Class 20 trip relay, making it ideal for high-inertia motor startups where standard Class 10 protection would cause nuisance tripping. This differential overload relay provides critical phase unbalance protection and phase loss sensitivity, ensuring the longevity of your 3-phase equipment by detecting irregularities before they lead to winding burnout.
Built for the TeSys Deca and TeSys D series, the LRD22L mounts directly to the bottom of LC1D25, LC1D32, and LC1D38 contactors, creating a compact and robust motor starter configuration. Techs will appreciate the manual-automatic reset selector and the dedicated stop/test buttons that allow for rapid diagnostics in the field. With a 690V rated operational voltage and multi-standard compliance including UL, CSA, and IEC 60947-4-1, this component is a standard-issue solution for contractors requiring reliable Square D motor control hardware that handles 17-24AMP loads without compromise.
Key Benefits for the Jobsite:- Direct Contactor Mounting: Optimized for TeSys D contactors (D25–D38), reducing installation time and enclosure space.
- Enhanced Motor Safety: Class 20 protection handles longer starting times, preventing unnecessary downtime while maintaining tight thermal oversight.
- Phase Failure Protection: Integrated differential detection automatically identifies phase unbalance to prevent single-phasing damage.
- Field Adjustable: Features a clear 17-24A adjustment dial for fine-tuning protection to the specific Full Load Amps (FLA) of the motor.
- Auxiliary Signaling: Includes 1 NO + 1 NC contacts for local trip signaling and integration into control circuits.
What contactors are compatible with the LRD22L?
This relay is designed for direct connection to Schneider Electric LC1D25, LC1D32, and LC1D38 contactors. For separate mounting away from the contactor, a LAD7B205 terminal block adapter is required.
Is this relay suitable for single-phase applications?
Yes, the LRD22L can be used in single-phase applications by wiring the poles in series to ensure the bimetallic strips react correctly to the current flow through all three phases.
What is the difference between this and the standard LRD22?
The "L" suffix designates this as a Class 20 relay, compared to the standard LRD22 which is a Class 10. This makes the LRD22L the correct choice for motors with longer starting cycles or higher starting torque requirements.
