New NEMA 4 Housing for AFB and NFB Damper Actuators
Versatile, Rugged, Weather Tight, Long Lasting
Belimo developed
unique NEMA 4 housing that incorporates its damper actuator product
lines. The design combined with extensive independent testing provides
complete, unmatched protection in extreme environments. Weather-tight
for the harshest indoor and outdoor conditions UV protected housing
will resist cracking and discoloration. Independently tested and listed
by North American and European agencies.
Ideal for extreme conditions
NEMA 4 actuators are weather tight
and UV resistant under the harshest conditions including rooftop
applications, wood drying kilns, agriculture and food industries. The
housing provides some internal space for customer installed components
such as a relay or controller. For high humidity or low temperature
(-40°F) applications.
• NEMA 4
actuators have been developed for similiar applications that do not
require corrosion resistant protection.
• New housings
offer NEMA 4 protection to our spring return AFB and NFB models.These
new models AFBUP-S N4, AFB24-MFT-S N4, NFBUP-S N4, NFB24-MFT-S N4 can
be found in our 2010 PGPL.
UL Type, NEMA, IP66 and IP67
What is the difference?
UL Type 4 and 4X enclosure rating
designations are independently tested by Underwriters Laboratories (UL)
in accordance with UL standard 50.
NEMA ratings are described in NEMA
standard 250. NEMA does not test or confirm these ratings. It is the
responsibility of the manufacturer to ensure these ratings unless an
agency lists the product, e.g. UL.
IP ratings are governed by IEC 60529
which is a European standard. IEC 60529 outlines an international
classification system for the sealing effectiveness of enclosures of
electrical equipment against the intrusion of foreign bodies (e.g.,
tools, dust, and moisture) into the equipment.
