Class 11 - 3RV\nmanual starters are used for single and poly-phase motors up to 20HP @ 575V.\nStarters have bimetallic heater elements to provide class 10 overcurrent\nprotection. Each starter has a fourth bimetallic strip that reacts only to the\nambient temperature inside the control panel. This ambient compensation helps\nprevent the starter from nuisance tripping when the panel temperature is\nhigher than the ambient temperature of the motor.. A built-in differential\ntrip bar causes the starter to trip faster on a phase loss condition to help\nreduce motor damage.. Magnetic trip elements in each starter take the device\noff line when it senses current of 13 times the maximum FLA dial setting..\nClass 11 - 3RV switches provide control for inherently protected motors.\nTypical applications include metal and woodworking machinery, grinders, power\nsaws, conveyors, fans, pumps, blowers, textile and packaging machinery, and\npaper cutters.. Class 11 - 3RV manual starters can be used as Type E self-\nprotected manual combination starters (up to 22 amps) per UL508 or as\ncomponents in Group Installation per NEC 430.53. When using the Class 11 - 3RV\nas a manual combination starter upstream protection is not required.. Class 11\n- 3RV controllers are available with low voltage protection which will\nautomatically open the power poles when the voltage drops or the power is\ninterrupted.. Controllers with the LVP option provide the OSHA requirements\nfor protecting personnel from potential injury caused by the automatic start-\nup of machinery following a voltage drop or power interruption when low\nvoltage protection is specified..
