Rectangular sensors are available for the following trip currents: 5-60A, 30-360A and 100-1200A. The table above lists the
available sensors sizes. Any window width (A1) may be combined with any window length. (B1)
Rectangular sensors are also available as a split core (take-apart) style for assembly to existing electrical installation without
the need for dismantling the primary bus or cables.
CAUTION:
Proper safety precautions must be followed during installation by a trained electrician. It is recommended that the incoming
power de-energized before installation. The sensor must have its secondary terminals short circuited or the relay connected,
before energizing the primary circuit .
