The first 4PDT ice cube relay with TRIPLE ratings for hazardous locations
Phoenix Contact is pleased to introduce our new four-pole, double-throw
(4PDT) triple-rated hazardous location (HazLoc) relay. The RIF-2..EX relay
is an ice cube-style relay offered as a fully-assembled module with either
screw or Push-in (PT) connection.
The triple ratings include UL Class I, Div. 2 for use in North America, ATEX
for use in Europe, and IECex, for HazLoc applications around the globe.
Phoenix Contact continues to innovate hazardous location relay technology
by offering a triple-approved, replaceable relay at roughly half the cost of
traditional competitors. With only six new part numbers that can cover
dozens of applications, having the right-priced relay in stock just became a
lot simpler.
Why develop it?
Hazardous locations can broadly be defined as areas that are at
risk of being exposed to flammable or combustible gases, dusts,
or vapors. Hazardous locations exist virtually everywhere in
industry – from oil and gas applications, to wastewater treatment
plants, pharmaceutical production, grain handling, and many
more.
Potentially explosive areas in the industry are subject to stringent
requirements that ensure the reliability and safety of electrical
equipment installed within them. Generally speaking, hazardous
location safety approval systems require that all equipment that
could be exposed to flammable or combustible atmospheres be of
a type suitable for installation in these areas. This includes
switching components such as relays.
The IECEx, ATEX, and UL Class I, Div. 2 approval systems all exist to ensure the safety of electrical devices
located within hazardous locations. There are, however, nuances that prevent the three from being considered
completely interchangeable with one another. To complicate matters, jurisdictions around the world continue to
implement these standards independently of one another, creating a regional patchwork of approval
requirements.
