Schneider Electric LT3-S 系列
●可与配有 PTC 热敏电阻探头的所有电动机一起使用。它监测绕组温度并确保不超过额定工作值，因此可以防止出现通常会造成过早老化的故障。它们还可用于监控表面温度。
●自动或手动重置
●远程复位
●在电源关闭时可进行故障存储
●故障指示
●测试功能

Schneider Electric LT3-S RangeCan be used with all motors equipped with PTC thermistor probes. It monitors windings temperature and ensures that the rated operating value is not exceeded, therefore guarding against faults which are often the cause of premature ageing. They can also be used to monitor surface temperature.Automatic or manual reset Remote reset Fault storage with the supply switched off Fault indication Test function Comparison Guide --- Model Type | Reset Detail LT3SE00F, LT3SE00M | Automatic reset without thermistor, short-circuit detection (without fault memory) LT3SA00M, LT3SA00ED, LT3SA00MW | Automatic reset with thermistor, short-circuit detection (without fault memory) LT3SM00E, LT3SM00M | Manual reset and therrmistor, short-circuit protection (with fault memory) ### 电动机保护 - 继电器

Thermal protection relay for series LT3 S motorsProtection relay with probe, LT3 series, that permanently controls the temperature of machines that require protection (motors, alternators etc..). Operates via CTP thermistor probes. Automatic or manual reset. Faults displayed on the front panel of the device or remotely, except for version LT3 SE, which does not have this function. Fault detection if the probe circuit is accidentally cut off Three versions are available: LT3 SE: Control devices with no fault memory. LT3 SA: Automatic reset with thermistor short circuit detection device. Warning light on front panel. LT3 SM: Device with manual reset and thermistor short circuit detection. On the front panel there is a fault warning light and voltage indicator, and a test and reset button.
