Installation Guidelines<\/h2>\n<h3>Selection Principles<\/h3>\n<ul>\n<li>Voltage matching: Choose fuse voltage rating according to actual AC \/ DC working voltage of your system.<\/li>\n<li>Current matching: Select fuse rated current to be 1.1\u20111.25\u202ftimes of circuit continuous working current; never use higher\u2011ampere replacement.<\/li>\n<li>Installation\u2011space consideration: Choose CNL \/ CNN when dedicated fuse\u2011base mounting is available; select ANL for compact\u2011space direct bolt\u2011on installation.<\/li>\n<\/ul>\n<h3>Installation &amp; Maintenance Tips<\/h3>\n<ul>\n<li>Disconnect main power supply before installation or replacement to prevent accidental short\u2011circuit.<\/li>\n<li>Tighten mounting bolts to required torque value, avoid poor contact and over\u2011heating caused by loose bolts.<\/li>\n<li>Check fuse status via visual indicator for CNL and CNN; test ANL integrity by multimeter.<\/li>\n<li>Only replace with identical\u2011model fuses to keep original circuit\u2011protection performance.<\/li>\n<\/ul>\n<h2>FAQ<\/h2>\n<p><strong>Q: What are CNL CNN ANL bolt\u2011down fuses?<\/strong><br \/>\nA: CNL CNN ANL bolt\u2011down fuses are heavy\u2011duty stud\u2011mount high\u2011current fuses for automotive and mobile\u2011equipment, for over\u2011current and short\u2011circuit protection of battery, alternator and high\u2011power loads.<\/p>\n<p><strong>Q: What is the main difference between CNL and CNN?<\/strong><br \/>\nA: Both adopt DIN43560 standard with same mounting dimensions.
