Housed in the control panel assembly, this fuse protects the heater's electrical circuits from overcurrent conditions that could damage control components or create unsafe operating conditions.\u003c\/p\u003e\u003cp\u003eThe FNQ series designation indicates a time-delay, midget fuse format, which allows brief inrush currents to pass without nuisance tripping while still responding to sustained overloads. The 500V rating provides a substantial voltage margin above the heater's operating voltage, and the 3A current rating is matched specifically to the control panel circuit requirements of these hydronic heating units. When a fuse of this type opens, the heater will fail to power on or will shut down unexpectedly. Inspecting and replacing this fuse is a straightforward diagnostic step when troubleshooting a non-responsive control panel.\u003c\/p\u003e\u003cp\u003eThis fuse fits the following Wacker Neuson models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eE700M\u003c\/li\u003e\n\u003cli\u003eHP252\u003c\/li\u003e\n\u003cli\u003eHSH 350\u003c\/li\u003e\n\u003cli\u003eHSH 650\u003c\/li\u003e\n\u003cli\u003eHSH350\u003c\/li\u003e\n\u003cli\u003eHSH700G\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43401186082864,"sku":"WACKER-5200008087","price":44.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5200008087.jpg?v=1784137458","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-bussmann-fnq-3-3a-500v-fuse-5200008087-for-hydronic-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
