11RFA910 - Lovato - Thermal overload relay

<h3>Motor protection relay for three-phase lines</h3><p>This motor protection relay is designed for three-phase motor circuits where overload protection must be coordinated with monitoring of phase-failure and single-phasing conditions. It is used in control panels for pumps, fans, conveyors and industrial machines where the motor line must be supervised with a dedicated relay.</p><h4>Current setting and phase supervision</h4><p>current range 6-10 A; 3-pole three-phase execution; phase-failure and single-phasing sensitive; manual or automatic reset. The current range defines the motor load window to be protected and must be matched to the application during panel setup. Sensitivity to phase-failure and single-phasing helps detect operating conditions that can stress a three-phase motor even when the command circuit is still active. The 3-pole construction keeps the relay aligned with the three-phase power path.</p><h4>Reset and maintenance check</h4><p>Manual or automatic reset allows the protection strategy to be adapted to the machine sequence. During replacement or commissioning, compare the current setting, reset mode, wiring position and relay series with the electrical diagram before restarting the motor. After a trip, the cause should be checked on the motor line before the relay is reset.</p><p>For clear panel service, keep the relay setting, motor identification and trip information aligned. This makes troubleshooting faster and helps distinguish overload, phase-loss and wiring issues without adding assumptions outside the data available on the panel.</p><p>When several motors are installed in the same cabinet, a consistent setting record is important. The relay should be associated with the correct motor feeder, upstream protection and contactor group, so that future work can follow the same electrical path without confusing adjacent circuits.</p> <h3>Motor protection relay for three-phase lines</h3><p>This motor protection relay is designed for three-phase motor circuits where overload protection must be coordinated with monitoring of phase-failure and single-phasing conditions.
