1 Solidstate trip types Solidstate trip types, SA00E, 0E, 00E Features Equipped with a load current pretrip alarm Constantly monitors the load current, and outputs an alarm when the set current is exceeded. Adjustable rated current The rated current is easy to vary in 5 to steps using an adjustment dial. Wide trip characteristics The current and time for instantaneous tripping and short/ longtime delay tripping can be set by the user. Adjustable ground fault tripping determinate and set a current level for ground fault detection in the ranging between % to % of the rated CT current.

4 Solidstate trip types Pretrip alarm function Constantly monitors the load current, and outputs an alarm when it exceeds the set current. Helpful for preventive maintenance and power management. The pretrip alarm operates via an LED on the breaker surface and a contact output. Separate power supply is necessary. The pretrip alarm setting allows adjustment to, 0,, or 0% of the rated current. Multi protection function Wide trip characteristics with high precision. Either ground fault tripping or the pretrip alarm can be selected as an option (not both).
