Product Introduction
RT18-125 standard base is the basic version of RT18-125 PV Fuse base series, a cost-effective Ceramic Fuse holder designed for general 500V~1140V photovoltaic AC distribution circuits. Without built-in position microswitch and transparent blown fuse viewing window, it focuses on stable basic overcurrent protection for conventional PV combiner boxes. This Solar Fuse holder matches full range 22×58mm HM18 ordinary ceramic fuse links from 0.5A to 125A. Adopting UL94-V0 flame retardant PA66 shell and integrated thickened pure copper conductive frame, the RT18-125 PV Fuse base fully complies with IEC60269-2 standards, supporting maximum 80kA short-circuit breaking capacity when paired with gG ceramic fuses. It features simple plug-in replacement, low maintenance cost and stable long-term conduction, widely adopted in small & medium distributed solar power stations.

Product Advantage
Cost-Effective Basic Ceramic Fuse holder Different from W position-signal and Y indicator variants, this RT18-125 PV Fuse base removes extra monitoring components, greatly cutting procurement cost for mass solar projects. As standard Solar Fuse holder for conventional PV cabinets, it retains full overcurrent isolation performance while simplifying internal structure.
Stable Low Thermal Loss Conductive System The integral thick copper frame of this Ceramic Fuse holder provides uniform clamping pressure for 22×58mm ceramic fuses. Long full-load operation brings slight temperature rise, and flame retardant plastic shell blocks AC short-circuit arcs to avoid cabinet fire hazards.
Full Compatibility for General PV Layout This RT18-125 PV Fuse base fits all 0.5–125A HM18 ceramic fuse links. Unified outline dimension allows direct replacement of old Solar Fuse holder without cabinet rework for PV renovation projects.

FAQ
Q1: Which fuse links match this basic Ceramic Fuse holder?
A1: This RT18-125 PV Fuse base only fits HM18 ordinary non-indicator 22×58mm ceramic fuses, cannot cooperate with HM18Y signal-type fuses.
Q2: Does this RT18-125 PV Fuse base support remote circuit signal feedback?
A2: No, it belongs to basic version Solar Fuse holder without built-in position microswitch and blown observation window, unable to realize remote signal & visual fault checking.
Q3: Can this Ceramic Fuse holder replace W/Y type bases on old PV cabinets?
A3: Unified overall size of RT18-125 PV Fuse base series, direct interchange without modifying cabinet mounting holes.
