More Information
Summary:An electrical protection device (12) includes a first moving contact (66), a trip (114), and a switching mechanism (150) configured to switch between a standby configuration and a trip configuration, the first contacts being in a conductive position or an isolated position, respectively. The release is configured to switch the switching mechanism to a trip configuration when the release is excited by a predetermined type of electrical fault. According to the invention, the protection device comprises:-a slider (262) movable between a standby position and a tripped position, in which the slider switches the switching mechanism to the tripped configuration,-a slider spring (266) tending to move the slider from the standby position to the tripped position, and-a lock (264) holding the slider in the standby position in the locked position. The release is configured to switch the locking member from its locked position to an unlocked position when the release is energized.
