Motor Contactors Specifications

Help with Motor Contactors specifications:

Standard Rating


	Rating Standard:
	Your choices are...
	NEMA Rated		Starter sizes refer to a standardized rating system for electrical performance. The NEMA size ratings are categorized by the continuous current rating and horsepower at the rated voltages.
	IEC Rated		The IEC sizes are rated at the thermal current rating (the current the contactor can withstand without overheating) or the operational current (the capability of the contactor to make and break the current under different IEC Utilization Categories. eg. Utilization Category AC-1).
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Device Technology:
	Your choices are...
	Solid State		The device uses solid-state technology.
	Electromechanical		The device uses electromechanical technology.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	AC Motor Phase:
	Your choices are...
	Single Phase Motor
	Three Phase Motor
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Continuous Current:		Continuous current is also called continuous ampere rating. Typically, a manufacturer will list the NEMA size and the Ampere Rating for that size.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Thermal Current:		IEC ratings are based on thermal current.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Performance Ratings


	Motor Voltage:
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Single Phase Power Rating:
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Three Phase Power Rating:
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	DC Horsepower Rating:
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Additional Specifications


	Number of Poles:
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Control Voltage (Separate Control):		The control voltage, if different from the Motor Voltage. This is called "separate control" and means that the control circuit gets its power form a separate source, usually lower in voltage form the motor's power source.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Operating Temperature:		This is the full required range of ambient operating temperature.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
