INSTRUCTIONS FOR INSTALLATION Shunt Trip Release Z-LHASA
1. Function and Description:
The shunt trip release type is a remote release based on the working current principle. The de-
vice for modular installation has been designed for installation on DIN support bars according to EN 50022. It is
1,5 MU (=27 mm) wide, has an optical switching position indicator (red/green) and can be mounted subsequently
on the left hand side onto any PLHT, miniature circuit breaker of up to 6 module units. Remote tripping is possible
within a wide voltage range. An auxiliary switch Z-LHK which can be connected additionally permits transmission
of a message that switchoff has occurred.
The sequence of installation as shown in the diagram must be observed, i.e. the shunt trip release must always
be installed to the left of the PLHT and the auxiliary switch Z-LHK on the right side.
When applying a voltage within the permitted range, the shunt trip release responds virtually without delay and
causes internal tripping of the PLHT mounted next to it. At the same time, it cuts the power supply to its own trip
coil and thus prevents thermal overload of the triipping device in case of continuous tripping commands. Conse-
quently, excessive length of the tripping pulse does not cause damage to the device. However, a minimum pulse
length is required for reliable functioning. The switching toggles of the Z-LHASA and PLHT are coupled mechani-
cally in such a way that when the PLHT is activated the toggle of the Z-LHASA is moved simultaneously. In case
the PLHT is switched off manually, the Z-LHASA trips mechanically even if no control voltage is present. In case
of electric tripping of the PLHT, the Z-LHASA is also activated internally by mechanical means and goes to the
OFF-position. If an external obstacle prevents the ASA switching toggle from moving to the OFF-position, the de-
vice may still trip internally like any PLHT independently of the toggle position.
