Hazardous Transformers
Encapsulated transformers are rated for use in hazardous
locations as well as harsh industrial environments.
Encapsulation and rugged NEMA 3R enclosures protect the
transformer from dust and moisture while providing extra
shock and vibration resistance. UL Listed transformers fully
comply with the latest edition of the National Electrical Code
for Class I, Division 2, Group A-D locations when installed in
compliance with NEC 501.100(B).
Features
• Encapsulated (suitable for hazardous locations)
• Single phase: .05 – .25 kVA and .50 – 25 kVA;
ree Phase: 3 – 45 kVA
• Electrostatically shielded for quality power on sizes 1 kVA
and larger
• UL Class 200°C insulation system, 115°C temperature rise
under full load
• Conduit knockouts for side entry into wiring compartment
• .50 – 45 kVA units are encapsulated with electrical grade
silica and epoxy for industrial applications
Applications
• Industrial plants
• Chemical processing plants
• Water / wastewater facilities
• OEM equipment

• DIN Rail DC Power Supplies
• Constant Voltage Transformers
ese small, single phase, dry type distribution transformers
are designed and shipped as insulating/isolating transformers.
ey have a dual voltage primary and secondary that can
be connected for a wide range of voltage combinations. e
most common use is to buck (lower) or boost (raise) the
supply voltage a small amount, usually 5 to 27%. Buck-boost
transformers are in compliance with NEC Article 210-9,
Exception 1 when eld connected as an autotransformer.
Features
• Hardshell® encapsulated on sizes 5 kVA and below
• UL-3R enclosures for indoor or outdoor service (some sizes
may require the use of weathershields)
• Low cost, smaller, lighter, more ecient to operate than
equivalent isolation transformers
Applications
• Motor loads
• HVAC
• Low voltage lighting (when used as an
Isolation transformer)
• Sustained high or low voltage conditions
