OEM Cross Reference Seaflo MPN SFBS-25-03A Internal SKU BS2503A EAN / Barcode 6971170931873 Questions & Answers Is this a genuine original part? Yes, this is an authentic SEAFLO product, manufactured to the highest marine standards for high-amperage applications. How do I know if it is compatible? Check the current draw of your pump. If your pump draws 25 Amps or less, this switch is designed to handle it. It is primarily used for pumps with flow rates above 3000GPH. What is the difference between BS2503A and BS2503B? The BS2503A (this model) is the standard version without a filter/strainer housing. The 'B' model typically includes a detachable strainer housing to protect the float from debris. Note: Always ensure electrical connections are made above the water level and sealed with marine-grade waterproof sealant (e.g., heat shrink butt connectors). Domain: 4boats.co.uk
