But unlixe the fuse which must be replaced, simply gushing the Re-Cork-It prolctors reset bullon closes the circuit again once ihe electrical prob lem has been conected. Positive action The Re-Cirk-It protector trips withoul delay upon short cireuil and wilh a controlled delay (see time delay curves) woon sustained over- loads. Upon tripping, Ihe contacts apen with a positive snag action, Ihereby suppressing ihe arc.

Reliable operation KOT operalion is based upod the aclon ola bimetallic element When Ihe host electrical equipment is operting normally, the contact on the bimetallic element is part of the circuil in series with a fixed contact (see cross-sectional drawing). The contact on ihe bimetallic element tits Ihraugh a hole in the non-conduelive slide, It halds lhe warting button in place agains! the force of ihe slide return spring. Winer 2 Suslained overcurrent heals the bimetallic element, il snaps ile comiact away Irom the fixed contact and oul of the bale in the slice breaking Ihe cirturl and shutling down the aquigment. The spring forces Ihe waming butlon out of the housing. Separation of the contacts is maintained by the non-conductive slide. When ihe bulton is pushed back into the housing (alter the electrical lault has been cleared), the contact snaps back inke the hole in ihe slide, makes connection with the lived coniact and closes the circuit. Easy installation The Re-Cirk-lt reseltable circuil protector is easily inglalled ina 48" fund or D-shaped panel cutout similar to that used for conventional panel-mounied luseholders. Han be mourned either Irom trond or rear, and i held in place by special hardware (see dimension drawings). Its 14" quick-conmect terminals are solderable. Wide selection of ratings The Re-Cirk-It protector is available in a range af ralings from 0.254, Ihrough 104 at 250 Vac andfor 50 Vode. Also to 154 at 250 Vac andor 32 Vide.
