Wire Size: #28-14 AWG
Torque: 2.25 lb. in.
Open Fuse Indicator Status Output Description:
The open fuse indicator status output acts very much like
an on/off switch. With all three fuses in place and operating
properly, this status output has a high resistance value of
greater than ten mega-ohms. When one or more of the fuses
are open, the status output becomes turned-on with a
resistance value less than 35 ohms. This status output
withstands voltage (AC or DC) up to 35 volts at off-state
and conducts current up to 40 milli-amps at on-state.
Applying voltage and current exceeding these limits will
result in damage to the components inside this status output
device permanently. There is some time-delay when the
status output changes on/off state. The open fuse
communications or status output device includes optical
isolators within the unit.
Communications output states:
Fuse Good
NO - High Resistance, >10 mega-ohms
Opened Fuse
NC - Low Resistance, < 35 ohms

Note: When energized, a low load terminal voltage will be present when fuses are
open or when pullout module is removed. The leakage current is limited to
.5mA maximum.
Note: Operating this device beyond the above limits will
cause permanent damage to the components on
the board.
For applications requiring status output below a system
voltage of 460V, contact Bussmann.

*The communication device requires a minimum circuit voltage (1L1-3L2-5L3) of
460 volts for the status indicating device to operate. Below 460 volts, but above
120 volts the indicator lights will luminate, but there will not be any communication
status output.
