Product Introduction
The RT18-125 W Fuse Holder is a signal-equipped DIN rail fuse base designed exclusively for PV power distribution systems, supporting quick tool-free TH35 rail installation and built-in auxiliary microswitch to feed real-time on/off position feedback signals. Compatible with full-range 0.5A–125A PV Ceramic Fuse sized 22×58mm, this RT18-125 Fuse variant fits AC500V/690V/800V/1000V/1140V low-voltage circuits, widely deployed in PV combiner boxes, energy storage cabinets and industrial automation control panels. Constructed with high flame-retardant PA66 housing and integrated thick pure copper conductive parts, the position signal module of this RT18-125 Fuse works stably under long full-load operation. It can remotely transmit circuit open/closed status to monitoring PLCs, eliminating manual cabinet inspection and greatly improving operation efficiency for large-scale solar stations, while maintaining perfect matching performance with all standard PV Ceramic Fuse models.

Product Advantage
Unique Built-In Position Signal Function, Exclusive RT18-125 Fuse W Variant Different from ordinary RT18-125 Fuse without signal, this RT18W-125 holder integrates precision auxiliary microswitch. It outputs reliable on/off state signals to remote monitoring systems, enabling unattended operation of PV stations and avoiding frequent manual cabinet opening to check PV Ceramic Fuse circuit status.
High Safety Flame Retardant & Low-Temperature Rise Design Heat-resistant PA66 insulating shell resists deformation under continuous high ambient temperature. Thick pure copper conductive structure of this RT18-125 Fuse minimizes power loss, no hidden overheating risks even when matched with high-current PV Ceramic Fuse for long-term full-load running.
Standard DIN Rail Modular Maintenance Snap-on TH35 rail installation without tools; only replace damaged PV Ceramic Fuse after faults. The RT18W-125 base can be reused for many years, effectively cutting spare part procurement and labor costs for medium & large photovoltaic projects.

FAQ
Q1: Can this RT18W-125 Fuse Holder transmit real-time circuit position signals for PV systems?
A1: Yes. As a signal version of RT18-125 Fuse, it has a built-in microswitch that outputs accurate on/off signals to PLC monitoring devices, so operators can remotely check the working state of PV Ceramic Fuse without opening distribution cabinets.
Q2: What is the maximum allowable working voltage of this position signal fuse base in solar cabinets?
A2: It supports up to AC1140V rated voltage, fully meeting the safety requirements of 800V PV power circuits when matched with standard PV Ceramic Fuse.
Q3: Does the auxiliary position signal component have long-term anti-vibration performance?
A3: The signal microswitch passes vibration aging testing, maintaining stable signal output after years of continuous operation with the RT18-125 Fuse and PV Ceramic Fuse in PV stations.
