Thermal Overload Relay Curve at Nelson Kennedy blog

Thermal Overload Relay Curve. Regardless of the product style (nema or iec), overload relays respond to overload relay conditions according to trip curves. 1) the sirius 3ru11 thermal overload relays use a bimetal contactor and therefore do not require a control supply voltage. Since the relay should ideally be matched to the protected motor and be capable of close sustained overload protection, a wide range of relay adjustment is desirable. When properly applied, no matter how high the current drawn, the overload relay provides protection without tripping unnecessarily. Ta thermal overload relays are used with a line contactors for the protection of motors having a nominal voltage of up to 600vac max per. Overload or thermal protection protects all types of motor applications against overload currents. The trip class means that at 600% (6 times) of the maximum thermal current rating (or 600% of the actual dial setting on adjustable. The thermal overload relays are three pole relays with bimetal tripping elements (1 per pole). Features benefits 3ru11 3rb20/3rb21 3rb22/3rb23
