Its NC contact opens when the monitored switch position changes, giving a fail-safe signal for interlocking or alarm circuits. It measures 11 x 37 x 21 mm and weighs 0.015 kg.\u003c\/p\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003e1SCA022744R2240\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eAccessories for Enclosed Change-over and Transfer Switches\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalog designation\u003c\/td\u003e\n\u003ctd\u003eOA8G01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEAN\u003c\/td\u003e\n\u003ctd\u003e6417019241302\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Auxiliary Contacts NC\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConventional Free-air Thermal Current (Ith)\u003c\/td\u003e\n\u003ctd\u003e16 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConventional Thermal Current (Ithe), Fully Enclosed\u003c\/td\u003e\n\u003ctd\u003e16 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Voltage (Ur)\u003c\/td\u003e\n\u003ctd\u003e690 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRated Insulation Voltage (Ui)\u003c\/td\u003e\n\u003ctd\u003e690 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Width\u003c\/td\u003e\n\u003ctd\u003e11 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Height\u003c\/td\u003e\n\u003ctd\u003e37 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Depth \/ Length\u003c\/td\u003e\n\u003ctd\u003e21 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e0.015 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eSelection Notes\u003c\/h2\u003e\u003cp\u003eAn NC auxiliary contact is the fail-safe choice for interlocks, since loss of signal wiring or power reads the same as a change of switch state; pick the NO auxiliary contact variant in the same accessory range instead when the control logic needs a positive 'switch is in this position' signal rather than a loss-of-signal alarm.
