The Bryant line of manual motor controllers (MMC) now available through AutomationDirect is UL listed as "suitable as motor disconnects." Because the NEC recognizes that a controller and disconnect can be the same unit (article 430.109), Bryant has designed a compact controller to meet the rigorous demands of a motor disconnect. By utilizing Bryant's MMC devices, the user benefits from the convenience of one device fulfilling two needs. Bryant's controllers feature thermoset bodies, to provide high resistance to electrical arc tracking, and AC-rated silver alloy contacts for conductivity and extended life. The compact devices are available in NEMA 1, 3/3R and 4X enclosures; each controller has lockout/tag out capability. Bryant Toggle AC manual motor controllers feature quick-make/slow break operation to provide reliability and long life. Each toggle switch controller has a 10,000 amp 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 60 Amp sizes, up to 600 VAC, and 2-pole and 3-pole configurations. 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 with1/2" 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 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 1/2" NPT wiring knockouts for 30 Amp models; 60 Amp models feature 3/4" and 1" conduit knockouts. NEMA 4X enclosed rotary AC manual motor controllers, suitable for heavy wash down 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.
