SKU: ORCATX-103IS Category:


The ORCA TX-103IS has been certified as a UL913 Intrinsically Safe Apparatus for use in Class I, II & III, Division I Hazardous (Classified) locations.

Intrinsic safety is a requirement that may be applicable to devices that are being operated in areas where the potential for fire or explosion exists because of gases, dust or easily ignitable fibers in the atmosphere. In short, an intrinsically safe piece of equipment won’t cause an explosion by igniting the flammable agents.

Intrinsically Safe approval certifications are made up of multiple classes, groups and divisions that correspond to the specific hazardous environment a device is approved to operate in. Each class consists of two divisions and certain classes have multiple groups. For example, Class I includes flammable gases, Class II includes flammable dust, and Class III includes flammable fibers. Each class has two divisions. Division 1 includes environments where explosive material is present in the air at all times. Division 2 includes environments where explosive material is stored in sealed containers, and explosive material is only present for short time intervals (when a failure occurs or during maintenance).
