DESCRIPTION

The Kele Models CS1A, SCS1.5A, CS1150A and

SCS1150A are solid-state switches that operate when the

AC current level sensed by the internal current transformer

exceeds a ﬁxed or adjustable trip point. Internal circuits

are totally powered by induction from the conductor being

monitored. There is zero off-state leakage current in the

solid-state relay output that can switch AC or DC circuits. The

Smart LED indication option eliminates the need for meters

when setting the adjustable trip point of the current switch.

Solid-core and split-core models are available.

FEATURES

• Models with ﬁxed or adjustable trip point

• Switch AC or DC circuits

• Power and status LED

• Applicable for VFD applications down to 6Hz

• Powered by monitored line

• Available in solid-core models or split-core models that

clamp easily around cables

• One-year warranty

• UL listed, CE certiﬁed
