RANGE OF MOLDED CASE LOW VOLTAGE CIRCUIT BREAKERS

摘要

A range of molded case low voltage circuit breakers is achieved from standard single-pole units, having an envelope made of insulating molded material (11) containing the contacts and extinguishing chambers. A multipole circuit breaker is achieved by arrangement of several single-pole units (10) in a common case (31), arranging between the single-pole units (10) a gap defined by a spacer (32), to achieve a modularity defined by the width of the case of the single-pole circuit breaker of the range. The spacer (32) comprises an overpressure actuator (45).
