The Allen-Bradley 140G-R-BC12 Molded Case Circuit Breaker Protection Door is an IP 54 rated mounted protection door for the Allen-Bradley Bulletin 140G series of circuit breakers. The 140G-R-BC12 Protection Door belongs to the 140G and 140MG accessories family, and it is compatible with the R-Frame Circuit Breakers. The R-Frame Circuit Breakers are complete factory assembled circuit breakers with ratings from 2000 Amps to 3000 Amps and they are available in either 3-pole or 4-pole setups. These breakers have a maximum interrupting rating of 12 Kilo-Amps (KA) and they are suitable for circuits with an operating voltage range of 240 to 480 Volts AC. The R-Frame Molded Case Circuit Breakers are also available with either electronic protection units (Electronic LSIG long, short, instant, and ground fault) or a molded case switch (isolator), and they are also rated for either 80% or 100% use.
The 140G-R-BC12 Protection Door confers an IP 54 ingress environmental protection rating to all R-Frame circuit breakers, making them suitable for extreme applications and outdoor use. It protects the internal components of the R-Frame Molded Case Circuit Breakers from foreign objects or external contaminants, thus making them resistant to harsh environmental conditions. The 140G-R-BC12 Molded Case Circuit Breaker Protection Door has a transparent plastic cover that is mounted directly to the enclosure door, providing the operators with the means to view all of the breaker's internal components. This door can be mounted on the hinges of the control panel platform, and it comes with a lock and key that helps to restrict access to only authorized users. The 140G-R-BC12 Molded Case Circuit Breaker Protection Door provides a 0 to 55 degrees Celsius internal ambient operating temperature for its internal components.
