CEICON C3–C63 OVERLOAD RELAYS
l
CEICON overload relays should be backed up by HRC fuse links
selected from the following table.
When selecting a motor rated fuse link the recommended rating relates to
the largest rated current, eg for an application requiring a 50A fuse link, a
motor rated fuse link marked 32M50 should be used.

CEICON OVERLOAD RELAY CHARACTERISTICS
l
The 3-phase overload tripping characteristics are taken from a cold condition
in an ambient temperature of 20°C and are therefore worst case curves.
The tripping times should not be longer than those shown (it will be noted
that they apply over a range: curves for individual units will operate within a
narrower band).
It should be noted that the best single phasing protection is obtained when
the overload relay is operating at or near its maximum rating.
