2 Bulletin T Overview/Accessories Bulletin T Overload protection trip class / A Phase loss protection Ambient temperature compensation Auxiliary contacts ( N.O. and N.C.) Manual/automatic reset mode selectable Test function for auxiliary contacts Stop button Trip indicator Optional remote reset solenoid and external reset accessories The T bimetallic overload relays are ambient temperature compensated, ensuring that the tripping characteristic of the relay remains constant over an ambient temperature range of + C. These class / A overload relays include a differential mechanism for high sensitivity to phase loss conditions and provide reliable motor protection in normal duty applications. In addition, they can be used to protect against overloads in DCmotor and variable frequency drive applications. Table of Contents Product Selection... Accessories... Specifications...
