FAQ What is the function of the T1 and T2 terminals on the LT3SE00BD?The T1 and T2 terminals are for connecting the PTC thermistor probes embedded in the motor windings. The relay measures the resistance across these terminals to detect overheating. Do not apply external voltage to T1 and T2. Can this unit be used with 230V AC control voltage?No, this specific model, LT3SE00BD, is designed exclusively for a 24V DC control supply (Ue). Applying AC voltage will damage the unit. Other models in the LT3S range exist for AC voltages. What type of PTC probes is this relay compatible with?The LT3SE00BD is designed for use with PTC thermistor probes that conform to the IEC 34-11-2 standard. This typically involves a set of 1 to 6 probes connected in series. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
