Its 600VAC\/300VDC maximum ratings, along with separately specified AC and DC interrupting capacities, give you concrete electrical characteristics to compare against the requirements of the equipment being serviced. It is also a natural replacement candidate when the equipment documentation specifically identifies JLLS045, provided you confirm all application and mounting requirements.\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.
