WHY 800KA?

MCG manufactures the world's largest range of SPDs--from I-peaks of 20kA up to 800kA. But 99.99% of recorded lightning is below 300kA. So why do we manufacture an SPD with 800kA? There are several reasons:

With MCG protectors the larger the I-peak capability:

	The more protection paths per phase there are. (In the SF800XT, there are 20 paths per phase. The 202XT has 5 paths per phase. The SurgeFree 120 and 160 series have 2 paths per phase.)
	The greater the joule rating. This means the larger the protector, the more joules of heat the protector can safely dissipate.
	The greater the clamping ability. MCG can clamp high amplitude surges down to safe levels. A SurgeFree 160M for example, can clamp a 10kA 6kV surge down to 1kV.
