Intrinsically Safe

The term Intrinsically Safe (I.S.) and also known as explosion-proof is often used generically to describe products destined for hazardous (explosive) areas. In reality, I.S. is a protection concept based around limiting the available electrical energy to nonincendive levels so that sparks cannot occur from short circuit or failures which could cause an explosive atmosphere to ignite.

Here you'll find an extensive grouping of products that offer you the necessary protection using I.S. standard to keep you and your teams safe for all your applications.
