CFPV-H3LB Fuse Base for CFPV-H3L Fuse 1500VDC 125-500A
The CFPV-H3LB Fuse Base is applicable for CFPV-H3L Fuse 1500VDC 125-500A. It is specifically designed to protect and isolate Photovoltaic (PV) combiner boxes and other DC system.
This fuse set is suitable for PV inverter protection and combiner boxes applications.
It is small in size, saves space, has high steel plate strength and is durable. The NH screw mount is best placed in the cabinet of the Photovoltaic system.
DC Fuse mainly used in DC combiner box in solar PV systems. When PV panel or inverter caused overload or short circuit, it trip off immediately, to protect PV panels, DC fuse aslo used to protect other electrical parts in DC circuit, when overload or short
circuit.
Application:
PV combiner
Inverter
PV array protection
Re-combiner
In-line PV module protect

FAQ
Q: What is the pre-arcing time of a fuse?
A: Interval of time between the beginning of a current large enough to cause a break in the fuse_element(s) and the instant when an arc is initiatedinterval of time between the beginning of a current large enough to cause a break in the fuseelement(s) and the instant when an arc is initiate.
Q: What is the total clearing time of a fuse?
A: Sum of the pre-arcing time and the arcing time.
Q: What is the power dissipation (in a fuse-link) of a fuse?
A: Power released in a fuse-link carrying a stated value of electric current under prescribed conditions of use and behaviour.
