WATSN SERIES PC level automatic transfer switch WATSN-100/32/4A NA00324 100A/160A/250A/630A
The benefits of this new generation TransferPacT WATSN can be described as "compact and exquisite, with great promise" in words:
Compact: with small footprint, it can fit into very limited spaces. With a small form factor, the width of the cabinet can be as low as 400mm.
Exquisite: unique and ingenious design. Three positions of excitation are integrated to provide fast switching in milliseconds.
Refined: excellent performance resulting from repeated honing: category AC-33B, full range of short-time withstand current (Icw).
Quality:quality and safety always come first. Automated lean production line creates high quality products with intelligent manufacturing.
Great: smart and classic. Full-range controllers support Modbus communication protocol to enable full interconnection.
Diverse: meet different needs-simple and complete controls, full multi-system certification.
Flexible: allow flexible building and expansion. Modular design allows customized function expansion.
Tailored: designed for your needs. Fully equipped with TIDE 2.0 intelligent control system and unified platform architecture.
The new TransferPacT WATSN series automatic transfer switch is designed for switching between two power sources in a power supply and distribution system with a rated working voltage of AC 400V and below and a rated frequency of 50 or 60 Hz to ensure continuity, safety and reliability of key loads. Incorporating an excitation drive structure. With its outstanding performance and high-end quality, it is widely applicable in various environments and meets every single customer
Class PC
• Transfer switch equipment based on mechanical switching devices, that do not need electrical power to hold the main contacts open or closed and capable of making, carrying, and breaking currents under normal circuit conditions including operating overload conditions, and making and withstanding short-circuit currents.
Extract from IEC60947-6-1
WATSN automatic transfer switch is specially designed in accordance with the standard requirements for power transfer. It does not provide
protection but has a great withstanding and connectivity capacity. In other words, it can guarantee the safety of switch itself, and will not be
damaged due to failure such as overload or short circuit, thus keeping a reliable connectivity of circuits.
