BS IEC 62246-2:2007 pdf free.Reed contact units— Heavy-duty reed switches.
BS IEC 62246-2 This part of lEC 62246 applies to the switching performance of heavy-duty reed switches for usein industrial applications based upon Part 1.
This part of lEC 62246 specifies reliability tests, rated making and breaking capacities, ratedimpulse voltages,rated conditional short-circuit currents，temperature rise and constructiontesting in addition to the requirements of Part 1.
Heavy-duty reed switches are glass sealed contact units and include high pressure sealed types.This part of lEC 62246 does not apply to mercury-wetted reed contact units.
NOTE 1 Heavy-duty reed switches are mainly used within electromagnetic switching devices,valves,solenoids,power relays, etc., as the electromagnetic load switching elements. The load conditions should be selected from thestandard inductive loads and the load specifications specified in lEC 61810-1 and IEC 60947-5-1.
NOTE 2 For elementary relays using heavy-duty reed switches as contact elements, this standard should be usedtogether with IEC61810-1 and lEC 61811-1 as applicable.
NOTE 3 For electromechanical control circuit devices using heavy-duty reed switches as contact elements, thisstandard should be used together with lEC 60947-5-1 as applicable.
