2.3 Product description
The WIC1 is a CT-powered protection relay with inverse time and definite time protection characteristics and is
specifically designed for switchboards with CBs and small rated output currents.
Together the specific CTs and the WIC1 form a joint protective system. A low-energy coil is needed for realizing trip
of the CB.
Parameter setting can be done in different user-friendly ways. By means of casting all electronic components incl.
the housing are safely protected against climatic and mechanic influences.
In the WIC1 the following protection functions are realized:
 3 phase definite time over current and short-circuit protection with variable tripping times
(ANSI 50/51)
 3 phase over current protection with selectable inverse time characteristics and definite
time short-circuit current element (ANSI 50/51)
 definite time earth over current protection by internal calculation (ANSI 50N/51N) – (Option)
