Abstract
An electromagnetic circuit breaker assembly, comprising at least one circuit breaker, is provided with a reverse polarity circuit that reduces the voltage presented to the terminals of the circuit breaker to which it is electrically connected when the terminals are further connected to a source of voltage in reverse polarity. The circuit breaker assembly is tripped due to the reverse polarity set-up, and remains tripped until the polarity is corrected. The electromagnetic coil is continuous provided with sufficient voltage so that the breaker may not be manually reset until the polarity is corrected. Preferably, the breaker is mechanically connected with another circuit breaker to create an assembly that will protect circuitry and devices against both a reverse polarity condition and an overload condition under normal operation. To this end, the reverse polarity circuit does not affect operation of the circuit breaker assembly if the polarity is in accordance with the normal set-up.
