For each voltage phase connected to the PAN-42 sensor, a current-limiting device must be connected in series. Modular rail-mount fuse holders are
recommended.

For installations with more than one phase, one multiple-phase fuse holder should be used, so that all phases are disconnected at once when
the fuse holder is put in the open position. The neutral wire should not be connected through a current-limiting device.

The following are recommended fuse holders:
• Littelfuse LPSC series (LPSC0001Z for 1 phase, LPSC0002Z for 2 phases, LPSC0003Z for 3 phases)
• Cooper Bussman CHCC series (CHCC1DU for 1 phase, CHCC2DU for 2 phases, CHCC3DU for 3 phases)
 

Fuses used should not exceed 1A rating.

The following are recommended fuses (0.5A):
• Littlefuse KLKR.500
• Edison HCLR0.5
