Zhejiang Hongman Electric Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of rt18-125 fuse holder ac 1140v solar pv in China. We are committed to providing high quality customized products made in China with competitive price. Welcome to wholesale bulk cheap rt18-125 fuse holder ac 1140v solar pv from our factory.
Product Introduction
This 3-pole fuse base is a general low-voltage power distribution protection component, the standard specification is RT18-125 PV Fuse holder, compatible with 22×58mm ceramic fuse links. It is widely used for AC & DC protection scenarios including industrial AC distribution cabinets, PV combiner boxes, energy storage equipment, automotive DC power distribution and so on. Adopting integrated 3-pole modular molding design, the compact all-in-one structure brings neat and convenient installation & wiring, perfectly matching universal 35mm DIN rail, which acts as the basic protective accessory for complete low-voltage power equipment.
As a universal automotive Solar Fuse base, this product focuses on stable and reliable circuit protection against short circuit and overload. The housing is made of UL94 V0 flame-retardant insulated thermoplastic material, with maximum AC 1140V withstand voltage, compatible for both AC and DC circuits. It features high temperature resistance and anti-aging performance, running stably under rated 125A high current for long-term service. Without open-close position indicator and blown-fuse indicator, it owns simple yet durable structure with low failure rate, ideal for mass standardized distribution cabinet projects to lower total procurement cost of complete equipment.
This AC 1140V Solar Fuse base integrates a three-pole combined structure without the need for separate pole assembly. Installation is completed in one step. The flip-up fuse core compartment facilitates quick replacement of the fuse core, making maintenance operations simple. The housing is reserved with standard terminal positions, and it is compatible with multiple specifications of cable compression wiring.
