LSIG Sentinel trip unit
hw+ circuit breakers fitted with LSIG trip units are for use in electrical distribution applications.
They are used for the protection of conductors and loads in cases in which protection against
ground faults is required within the framework of a TN-S neutral system. The settings by
means of adjustment dials are accessible from the front of the products and allow precise
adjustment of the protection and a tripping curve independent of the ambient temperature.
