Many believe that installing circuit breakers in their home or facility eliminates the need for additional protection against surges. The reality is that while both devices are essential, they solve very different problems.<\/p>\r\n<p data-start=\"792\" data-end=\"1091\">Circuit breakers protect against overcurrent and prevent fires, while surge protectors (SPDs) guard against dangerous voltage spikes that can destroy sensitive electronics.

Grounding resistance should be below 10 \u03a9 for effective diversion.<\/p>\r\n<\/li>\r\n<\/ul>\r\n<p data-start=\"4851\" data-end=\"5225\"><strong data-start=\"4851\" data-end=\"4873\">Practical example:<\/strong><br data-start=\"4873\" data-end=\"4876\" \/>In UPS-protected data centers, a Type 2 SPD is installed upstream of the UPS rectifier. It prevents voltage spikes from damaging UPS electronics and batteries. Our product line supports this: the SLP40-275\/3S+1 Type 2 SPD works with a BRSCB dedicated breaker, while the BR-30FU SPD integrates a built-in fuse for compact installations.<\/p>\r\n\r\n<h2 data-start=\"5232\" data-end=\"5271\">Common Misconceptions and Mistakes<\/h2>\r\n<p data-start=\"5273\" data-end=\"5348\">From years of engineering experience, I\u2019ve seen the same errors repeated:<\/p>\r\n\r\n<ol data-start=\"5350\" data-end=\"6629\">\r\n \t<li data-start=\"5350\" data-end=\"5554\">\r\n<p data-start=\"5353\" data-end=\"5554\"><strong data-start=\"5353\" data-end=\"5397\">\u201cMy breaker protects against lightning.\u201d<\/strong><br data-start=\"5397\" data-end=\"5400\" \/>Wrong.
