Built to the DZ47-63Z \/ IEC EN 60898 DC standard, it delivers a 6kA rated breaking capacity with thermal-magnetic trip technology that responds instantly to both overload currents and dangerous short-circuit faults — protecting your solar panels, charge controllers, and battery banks from potentially costly damage. The 2-pole (2P) design simultaneously disconnects both the positive and negative conductors, providing a true isolation point that meets best-practice safety requirements for DC solar circuits.\u003c\/p\u003e\u003cp\u003eWhether you're building out a rooftop solar array on your caravan or motorhome, wiring a 4WD dual-battery system, or commissioning an off-grid cabin in the Australian bush, the MCB500202P gives you a reliable, standards-compliant protection and isolation device that's quick to install and easy to operate. Its 35mm DIN rail mounting drops straight into standard combiner boxes and distribution enclosures, while the clear ON\/OFF toggle lever makes manual isolation fast and unambiguous — ideal for roadside servicing, campsite troubleshooting, or any situation where you need to safely de-energise a DC circuit in seconds.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e500V DC rated, 2-pole (2P) configuration — simultaneously isolates both positive and negative conductors\u003c\/li\u003e\n\u003cli\u003e20A rated current with 6kA short-circuit breaking capacity for robust fault protection\u003c\/li\u003e\n\u003cli\u003eThermal-magnetic trip mechanism protects against overload currents and short-circuit faults\u003c\/li\u003e\n\u003cli\u003e35mm DIN rail mount for tool-free installation in combiner boxes and distribution enclosures\u003c\/li\u003e\n\u003cli\u003eCompatible with 24VDC–500VDC systems — suits caravan, motorhome, RV, marine, and off-grid solar\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Slocable","offers":[{"title":"Default Title","offer_id":56392995176614,"sku":"MCB500202P","price":49.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0466\/4688\/6566\/files\/MCB500202P.png?v=1776462114","url":"https:\/\/campingaustralia.com.au\/products\/mcb-500v-2p-20a-dc-solar-isolator","provider":"Camping Australia","version":"1.0","type":"link"}
