Help with Electrical Contactors facets:

Type



	Your choices are...
	Electrical Contactor		Electrical contactors are electrical devices used to switch high power in power circuits. Unlike relays, contactors are normally directly connected to the load (current carrying) circuit.
	Aerospace Contactor		Aerospace contactors are high-performance, high-capacity circuit controls designed for aerospace applications.
	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.

Features



	Your choices are...
	Time Delay		Contactors provide delay-on-make, delay-on-break, single-shot, recycling, and interval timing functions.
	Intrinsically Safe		Intrinsically safe (IS) is an adjective for equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most ignited concentration. The IS terminations and wiring may be brought into any hazardous location of any group classification for which it is accepted without requiring explosion proof housing or other means of protection.
	Visual Indicators		Contactors provide visual guidance for both power and signal monitoring.
	Hermetically Sealed		Contactors are hermetically-sealed to prevent contamination, the ingress of water, etc.
	Latching		Contactors "latch" into the actuated position. In other words, they stay in position until actively actuated to another position.
	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		The full-required range of operating temperature.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
