For AC service, verify that the circuit and equipment requirements are within the fuse's 600VAC maximum rating and are compatible with its 200 kA interrupting rating at 600VAC.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003ePhysical compatibility deserves the same attention as the electrical ratings. The equipment should accommodate the JLS350's knife-blade configuration and its fuse block, clip, or holder mounting method. The supplied specifications identify the LFJ60400 Series as the corresponding holder family. Confirming all of these characteristics together provides a much more useful compatibility check than selecting a fuse based solely on its 350A rating.\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003cdiv\u003e\n\u003cblockquote\u003e\n\u003cp style=\"font-size: 12px;\"\u003e\u003cem\u003eUse of Original Equipment Manufacturer (OEM) trademarks, names, and logos is for informational and identification purposes only.
