2P Pole DIN Rail Switch Disconnector
Rehemeter Electric is a professional manufacturer of low-voltage power distribution equipment. Our SF219G Small Dual Power Source Transfer Switch is a DIN rail-mounted manual transfer switch designed for reliable dual-power switching, overload protection, and short circuit protection. Featuring a V0 flame-retardant shell, high-quality copper terminals, double-layered thickened handle, and flexible modular combination, it ensures safe and stable power switching for residential, commercial, and photovoltaic power systems. With complete specifications (1P/2P/3P/4P, 16A-80A), long service life, and support for OEM/ODM, it provides cost-effective power safety solutions for global customers.
Product Description
Our SF219G Small Dual Power Source Transfer Switch is a compact, high-performance manual transfer switch engineered for seamless dual-power switching. It enables safe isolation and switching between two independent power sources, with built-in overload protection, short circuit protection, and arc extinguishing functions to prevent electrical hazards. The V0 flame-retardant shell self-extinguishes within 30 seconds after high-temperature combustion, while high-conductivity copper terminals resist current surges and burnout. Ideal for household distribution, industrial control, and photovoltaic power generation systems, it delivers 24/7 reliable power safety for your family and equipment.
NEW QUALITY UPGRADE & MORE DURABLE
Our SF219G transfer switch has undergone comprehensive quality upgrades. Precision-engineered from the inside out, every component is meticulously inspected from material selection to final assembly. We utilize high-precision internal components and advanced manufacturing processes to ensure stable performance and long service life. The shell is made of high-strength V0 flame-retardant engineering plastic, which is heat-resistant, impact-resistant, and anti-aging. Each product undergoes strict aging tests, electrical life tests, and flame retardant tests before leaving the factory, enabling long-term stable operation in harsh environments.
STRUCTURAL ANALYSIS
The transfer switch adopts a compact and scientific structure, including 6 core components:
1. LINE INPUT END : Top terminals for dual power source input, marked for easy wiring.
2. CHOTAI LOGO & PRODUCT PARAMETERS : Clear brand identification and technical specs (SF219G 63A, 400V~ 50Hz) for quick reference.
3. WIRING DIAGRAM : Intuitive panel diagram to avoid wrong wiring during installation.
4. DOUBLE-LAYERED THICKENED SPLIT HANDLE : Ergonomic design for comfortable operation, improving service life and operational fullness.
5. OUTGOING END : Bottom terminals for load output, with secure screw fixation.
6. DIN RAIL MOUNTING CLIP : Standard 35mm rail design, gently press to lock firmly for easy installation.
DOUBLE-LAYERED THICKENED HANDLE FOR COMFORTABLE OPERATION
Equipped with a double-layered thickened D-type handle, the SF219G transfer switch improves service life while increasing operational fullness and comfort. The ergonomic curvature conforms to human operating habits, reducing fatigue during frequent switching, and the high-strength engineering plastic handle is wear-resistant and durable for long-term use.
