Bulletin 1694 Electronic circuit protection for 24V DC
(Cat xxxx-xxx)
WARNING: Electrostatically sensitive sub-assemblies can be destroyed by voltages far below the human perception threshold. These voltages already occur if you touch a component
or electrical terminals of a sub-assembly without being electrostatically discharged. The damage of a sub-assembly caused by an overvoltage is often not immediately
recognised, but will be noticed only after a longer operating time.
Mounting or actuation of the 1694 connector arm must only be effected at dead-voltage. For start-up the 1694 connector arm must be closed.
Device to be installed, operated and maintained by trained personnel only.
The device can’t be serviced or repaired.
To secure device properly against unintended access, product shall be mounted in locked cabinet.

Bulletin 1694 Electronic circuit protection for 24V DC
• Connection to a higher or not reliably disconnected voltage can cause hazardous conditions or damages
• Only the intended circuit protectors must be used
• The technical data of the circuit protectors used have to be observed
• The entire power distribution system must only be installed by qualified personnel
• Only after expert installation must the device be supplied with power
• After tripping of the circuit protector and before reset, the cause of the failure (short circuit or overload) must be remedied
• The national standards have to be observed for installation and selection of feed and return cables.
• Combination of supply modules, circuit protection and power distribution
• Selective load protection by means of electronic trip curve
• No accessories required for connecting the components
• Width per channel only 12.5 mm (1-channel) or 6.25mm (2-channel)
• Integral fail-safe element, adjusted to current rating
• Switching capacitive loads up to 20,000 µF (at IN > 6A)
• Manual ON/OFF/reset momentary switch
• Clear status indication by means of LED and auxiliary contact (1694-PF supply module)
• Connection via push-in terminals
• 1694-PMx available in Class 2 version with nominal currents: 1A, 2A, 3A, 4A
Bulletin 1694 Electronic Circuit Protection is a modular solution with a max. system capacity of 40A. The protection modules come in a fix current rating
in a range from 1A…10A. Designed for 24V DC circuits, the 1694 provides comprehensive protection against short circuit and overcurrent conditions
while allowing for inrush current.
