Note 1: LTD operating time t

LTD

is calculated by the following equations.

(I/1.1155Ir) a -1 x T L


Ir = 0.5~1.0 x In (A)

T

L

= 1~18 (s)

The accuracy of operating time is ± 30% (1.5Ir

≦ load current<4Ir) or ± 20% (4Ir ≦ load current).

LTD operating time is 0.8s(FLAT) when the operating time becomes 0.8s or less.

Note 3: When Tsd = "0.06" setting, operating time is 0.04~0.08s.

I 2 t is selectable : ON or OFF.
