Rated at 40 amps, it is engineered to protect high-draw circuits — such as compressor fridges, electric winches, auxiliary lighting, and solar charge controllers — from damaging overcurrent events. The surface mount housing allows direct bolt-to-panel or bracket installation, eliminating the need for a dedicated fuse holder and making wiring neat and accessible. Once tripped, the breaker resets manually with a simple button press, so you are never left hunting for a spare fuse in the middle of the Australian outback.\u003c\/p\u003e\n\u003cp\u003eDesigned for the demands of off-road travel and remote-area camping across Australia, the AS-CB40SM suits installations in caravan battery compartments, 4WD dual-battery trays, RV control panels, camper trailer electrical boxes, and motorhome service bays. Its compact, vibration-tolerant construction handles corrugated dirt roads and rough bush tracks without nuisance tripping, making it a trusted choice for serious grey nomads, overlanders, and weekend warriors who rely on a dependable 12V system. Whether you are protecting a portable fridge running off your second battery, securing a hardwired DC–DC charger circuit, or safeguarding an onboard 240V inverter feed, this circuit breaker is a straightforward, long-service upgrade over standard blade fuses.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e40A rating protects high-draw 12V\/24V DC circuits including fridges, winches, and lighting\u003c\/li\u003e\n\u003cli\u003eResettable design — push-button manual reset eliminates the need for replacement fuses\u003c\/li\u003e\n\u003cli\u003eSurface mount housing for direct panel or bracket installation — no separate fuse holder required\u003c\/li\u003e\n\u003cli\u003eVibration-tolerant construction suits corrugated outback roads and off-road 4WD use\u003c\/li\u003e\n\u003cli\u003eCompact form factor fits caravan battery bays, 4WD dual-battery trays, and RV control panels\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AllSpark","offers":[{"title":"Default Title","offer_id":56393094987942,"sku":"AS-CB40SM","price":49.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0466\/4688\/6566\/files\/AS-CB40SM_7b44473d-d7e5-4793-b23d-7ac327974215.jpg?v=1776472695","url":"https:\/\/campingaustralia.com.au\/products\/allspark-circuit-breakers-surface-mount-40a","provider":"Camping Australia","version":"1.0","type":"link"}
