Abstract (en)
[origin: EP0028389A1] 1. A single- or multi-pole low-tension line circuit breaker with a contact position (22, 24) comprising a movable contact (22) and a fixed contact (24) for each pole, having an arc extinction chamber associated with the contact position (22, 24), on which position by means of a switch mechanism (12) an overcurrent trip acts in the event of an overload current or short circuit current, the fixed contact (24) being mounted on a guide bar which forms both an arc guide bar (26, 50) and a terminal, characterised in that the contact position (22, 24) is associated with a component (42, 58a, 63, 64) which is made from a memory alloy and which is deformed when and after its transition temperature is exceeded and so forces the contacts irreversibly apart.
