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.

Starter Ratings


	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.

	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:
	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:
	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.

	Overload Protection:
	Your choices are...
	Eutectic		Eutectic overload relays consist of a eutectic (melting) alloy and a heater coil. When an overload occurs, the heater coil heats the eutectic alloy tube. The heat melts the alloy tube attached to tripping device, initiating a switching action.
	Bimetallic		A bimetallic device is made of two strips of different metals that are permanently joined together. Heating the strip causes it to bend because the metals expand and contract at different rates. The strip is attached to a spring on a contact. As the strip bends, the spring pulls the contacts apart, breaking the circuit.
	Solid State		The solid-state relay measures current or a change in resistance instead of generating heat to facilitate a trip. The solid-state relay also provides advanced functions (i.e. ambient temperature sensing, programmable trip time and detecting changes in current).
	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.

	Additional Features
	Your choices are...
	Low Voltage Protection		If the line voltage drops or fails, the contactor will latch open and stop the motor. It must be manually reset to restart the motor.
	Phase Failure (Loss) Trip		If power fails is one wire of a polyphase circuit, power is interrupted in all the wires.
	Phase Reversal (Unbalance) Trip		If phase rotation reverses in a polyphase circuit, power is interrupted in all wires of the circuit.
	Multi-Speed Starter?		Multi-speed starters are designed to be operated at constant frequency and voltage.
	Reduced Voltage Starter (RVS)		Reduced voltage starters (RVS) use motor windings that may be reconnected to form different numbers of poles to change speed. It is designed to be operated at constant frequency and speed.
	Reversing		Reduce voltage starters are used when there is a need to avoid overloading the power distribution system (utilities impose limits on the amount pf power their customers may draw at any one time) or to avoid unnecessary wear and tear on equipment by reducing starting torque. The five main types of Reduced Voltage Starters are Primary Resistor, Autotransformer, Part Winding, Wye Delta and Solid State.
	Full Voltage Non-Reversing Starter		Full-voltage non-reversing starters are designed with two contactors (one for forward direction and one for reverse) and an overload relay. The contactors are mechanically and electrically interlocked.
	Manual Starter		Manual starters are the most commonly used general purpose starter. These starters connect the incoming power directly to the motor and are particularly suitable for squirrel cage motors. They can be used in any application where the motor runs in only one direction, at one speed and where the draw of inrush current at start up is not a concern.
	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.

Environment


	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.
