Zusammenfassung:A parallel pole magnetohydraulic circuit breaker (10), having a single trip element (271) and a pair of trip mechanisms (101, 102), achieving an increas ed current carrying capacity with reduced nuisance trips. The trip mechanisms (101, 102) are contained wit hin separate housings (14, 16), with electrical connections (30, 40) and multipole trip mechanism (101, 102) communicating through apertures in the common wall (14'). Preferably, the armature (260) o f the trip element (271) acts on a single trip mechanism (101, 102), which multiplies the available force to trigger a trip of the other trip mechanism .
