some cases these contacts may be connected in parallel for high current ratings isolation of single pole construction permits lower tooling costs and facilitates pole to pole electrical and magnetic isolation where needed the similar size and geometry for both contactors and eobcp 200 will allow for simplified control panel layout and power cabling safety contactor functions can be done with a single device rather than with two as is common today the smaller footprint will allow for smaller enclosures lower panel projection and reduced heat dissipation eobcp 200 is well suited in size performance and cost for protecting the line side of invertors and variable frequency drives they will also be ideal for isolating the load side of invertors and variable speed drives when used in place of a standard circuit breaker eobcp 200 has the potential of simplifying the traditional through the door mechanically interlocked operator also the combination of electrical and mechanical operation creates new opportunities for cost reduction and safety for enclosed equipment electrical interlocking is simpler and provides two levels of safety the first is by means of a door switch and the second by means of a lockable handle on the switch mechanism eobcp 200 allows the circuit breaker function to.
