This new series of controllers are made to replace ordinary electromechanical circuit breakers, and can switch, monitor, report status and provide circuit protection for circuits from 2 to 25 amps within MIL-STD-1275 voltage limits and conditions. They offer current flow status, load voltage status, trip status signals and built-in transient suppression. They offer the protection of a traditional circuit breaker and the control options of solid-state technology. They measure 2.74 x 1.34 x .370 inches, or 69.6 x 1.34 x 9.4 mm, and have an additional 0.24 inches, or 6.1 mm for pin depth, and weigh 2.3 oz, or 65g. They cost $500 each in quantities of 500 units.
