Thy types CZ1, SZ1<\/strong> are current-sensitive switches, automatically resetting, with connecting cables, with or without epoxy<\/h5>\n
<\/h5>\n
The type CZ1<\/strong> is not isolated<\/h5>\n
<\/h5>\n
The type SZ1<\/strong> is insulated with a Mylar\u00ae-Nomex\u00ae cap<\/h5>\n
<\/h5>\n

 <\/p>\n

<\/h5>\n
<\/h5>\n
Ideal for installation on windings of electric motors, transformers or ballasts<\/h5>\n
