    • A parallel pole magnetohydraulic circuit breaker (10), having a single trip element (271) and a pair of trip mechanisms (101, 102), achieving an increased 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) of 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.
    • 具有单个跳闸元件(271)和一对跳闸机构(101,102)的并联极磁液压断路器(10),通过减少的扰动跳闸实现增加的载流能力。 脱扣机构(101,102)与独立的壳体(14,16)一起包含有通过公共壁(14')中的孔连通的电连接(30,40)和多极脱扣机构(101,102)。 优选地,跳闸元件(271)的电枢(260)作用在单个跳闸机构(101,102)上,该乘法器将可用的力乘以触发另一个跳闸机构的跳闸。
