Weboverload relay has no power contacts and cannot disconnect the motor by itself. The control circuit contact must be wired in series with the coil of the contactor so that the contactor will de-energize when an overload occurs. Square D manufactures three types of overload relays, the melting alloy, the bimetallic, and solid state. WebA melting alloy overload relay is standard. Its contact unit (item 7 in Figure 1) is available with a N.O. or N.C. isolated alarm contact, in addition to the standard N.C. contact. The contact unit with alarm circuit contacts is field-installable (see Table 5). Ambient-temperature compensated bimetallic overload relays, incorporating

Overview WebPhase Loss and Phase Unbalance. The most important feature offered by a solid-state overload relay (SSOLR) is phase loss protection. When a phase loss causes a significant current increase in the remaining phases of the motor circuit, there is a major increase in rotor current that can cause motor damage. The time it takes for a melting alloy ...
