controllers feature thermoset bodies to provide high resistance to
electrical arc tracking and ac-rated silver alloy contacts for excellent
conductivity and extended life. The compact devices are available in NEMA 1,
3/3R and 4X enclosures; each controller has lockout/tag out capability.
Toggle ac manual motor controllers feature quick-make/slow break operation
to provide reliability and long life. Each toggle switch controller has a
10,000A high-fault short circuit withstand rating, excellent dimensional
stability and superior dielectric strength. Optional NEMA 1 enclosures without
switches, as well as side guards for close wall applications and finger-safe
environments are also available.
Single-phase and three-phase toggle controllers are available in 30, 40 and
60A sizes, up to 600V ac, and 2-pole and 3-pole configurations. Designed with a
clamping plate for back or side wiring, toggle switch type controllers start at
Available enclosed toggle ac manual motor controllers feature NEMA 1 or NEMA
3R enclosures. NEMA 1 metal enclosed switch controllers, ideal for use in
indoor environments, are designed with 1/2 and 3/4 inch NPT wiring conduit
knockouts. The all-aluminum cover and base are designed with top, bottom or
back wire entry points; the base is pre-drilled for rear surface mounting. NEMA
1 enclosed toggle controller prices start at $27.50.
NEMA 3R rain-tight enclosed toggle controllers are available in either all-aluminum
or chemical and impact resistant thermoplastic enclosures, making them ideal
for outdoor applications. The all-aluminum enclosure, with pre-drilled base for
rear surface mounting, is designed with Â½ inch NPT wiring knockouts for 30A
models; 60A models feature Â¾ and 1 inch conduit knockouts. NEMA 3R enclosed
toggle controller prices start at $40.
NEMA 4X enclosed rotary ac manual motor controllers, ideal for heavy
washdown and corrosive environments, feature impact and chemical resistant
thermoplastic enclosure bodies. An over-center rotary switching mechanism
ensures reliable operation and allows positioning of up to two N.O. / N.C.
auxiliary contacts. NEMA 4X enclosed rotary controllers start at $99.
As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers.
