The circuit breakers used in the ACD-100 are high-inrush magnetic types designed specifically for critical data processing and broadcast applications where nuisance tripping cannot be allowed. They have a pulse tolerance* of 10 times the rated current, or 200 amperes. This makes them particularly suited for use with power amps and other devices with high-reactance loads, since the high pulse tolerance will keep them from tripping falsely at the instant power is applied or on musical peaks. If a breaker should trip, it can be reset as soon as the overload is corrected-there is no cool-down delay time required. Temperature compensations which affect fuses and inexpensive thermal breakers are not a concern. The breakers are of the highest industrial grade, NRTL-C TUV listed, precise in operation and rugged in construction. They may be used as on-off switches for the five circuits.
The ACD-100's design incorporates four oversized busses, allowing wiring for 120V or 240V single phase, or 208V three phase power. A strain relief clamp is provided that can accommodate a cable or wire bundle up to 1.5 inches in diameter. Cable termination is a simple process of breaking out and stripping the individual conductors and connecting them with set screws, and then tightening the strain relief clamp. Complete instructions accompanying the unit guide the user through the process of selecting and terminating the supply cable.
The ACD-100 provides basic spike and surge suppression, with metal oxide varistors (MOV's) connected between the hot and neutral conductors of each circuit. The MOV's respond to line-derived spikes in nanoseconds, clamping transient voltages to safe levels of 200V peak or less.
