IF

Fuse cards, with sum-alarm, are used to protect electronic circuits from damage due to overcurrent or short circuit.

IMPORTANT
Since the fuses are fixed and cannot be changed, the maximum load per output must not exceed 2.7 A. The maximum load for the entire board is 10 A.

What is a PTC fuse?

A PTC fuse, where “PTC” stands for “Positive Temperature Coefficient,” is a type of thermal fuse or overcurrent protection device. These fuses are used to protect electrical circuits from overcurrent and short circuits.
The fuse works by changing its resistance characteristic when it gets too hot due to high current. When the current becomes too large, the temperature in the fuse increases, causing it to become less conductive and restrict the flow of current. When the temperature in the fuse goes down, the fuse returns to its normal state and allows current to pass as usual.

MOUNTING IN BATTERY BACKUP

The card is delivered mounted in it’s plastic casing, for easy installation.
If the card has come loose, snap it back into the plastic casing.
Mount the card on any card slot in the enclosure, leave space for cables.

IMPORTANT
Install the board before screwing on wiring or commissioning. $milleteknik-A-FU122408OP02-8-Output-Module-PTC-fig- $2$$
