Description
The Model 2734 Current Sensitive
Relay monitors a single-phase AC current for an over-current
condition. A top-mounted current transformer (CT) provides
complete isolation from the control voltage as well as easy
installation.
Operation begins when the
current being monitored rises to 10% of the trip setting,
which initiates the start-up delay. When the delay expires,
over-current sensing begins.
In the AUTO mode, the Model
2734 resets when current drops below the trip setting. In
the MANUAL mode, the unit must be reset by momentarily switching
to the AUTO mode, and back, after the current fault is cleared.
The TRIPPED LED indicates the output relay status. Current
must drop below 10% of the trip setting for the start-up
delay to restart.
The standard model operates
in a non-failsafe mode; if control power is lost, over-current
detection is lost. A failsafe option is available, fixed
or switchable. An adjustable dead band option is also available.
