Product Description

Product Description:

The isolation power supply creates a definitive disconnection point, which is essential for ensuring maintenance safety. This type of power supply must be used together with circuit breakers to function properly and safely.

Switching operations involve changing the dual bus circuit or modifying the operating mode. These actions help in managing the electrical system's configuration and maintaining its optimal performance.

Turning on and off small currents is typically done when dealing with no-load lines, transformers with current less than or equal to 5 amperes, or lightning arresters. This allows for safe control of low-current components within the electrical system.


Features:

The product is designed to be safe and reliable, boasting a long mechanical lifespan. For instance, the GW9-12 model can endure up to 3 million operational cycles, making it an excellent choice for applications that demand durability. Additionally, it is well-suited for outdoor environments where harsh conditions are common.

Featuring a flexible structure, this product supports both manual and electric operation modes to accommodate different user preferences. Moreover, it offers customization options, such as the GW4-35/630A, enabling it to meet specific requirements and enhance overall functionality.


Applications:

The High Voltage Isolation Switch by TNNPI, manufactured in Henanzhengzhou and certified with CE and ISO standards, is a versatile and reliable solution designed for a wide range of application occasions and scenarios. With a robust protection level of IP54 / IP65 and an operating temperature range from -40°C to +55°C, this isolator switch 400a 3p is well-suited for both indoor and outdoor environments, ensuring dependable performance even under harsh weather conditions.

In industrial settings, the High Voltage Isolation Switch serves as a crucial component for safely disconnecting electrical circuits during maintenance or emergency shutdowns. Its switching capacity supports both load break and no load break operations, making it ideal for use in power distribution systems where interrupting current loads safely is essential. The isolator disconnect switch functionality allows operators to isolate electrical equipment without risk, thereby enhancing workplace safety and minimizing downtime.

Another common application scenario includes renewable energy installations such as solar power plants and wind farms. Here, the lockable battery isolator switch feature is particularly valuable, providing secure isolation of battery banks during servicing or system faults. This lockable mechanism ensures that the switch remains in the off position, preventing accidental re-energizing and protecting maintenance personnel from electrical hazards.

The product’s frequency compatibility with both 50Hz and 60Hz systems enables its use across various regional power grids, further expanding its applicability. Additionally, with a minimum order quantity of just 3 units and pricing ranging from $55 to $450 depending on specifications, the High Voltage Isolation Switch offers cost-effective scalability for both small-scale and large-scale projects.

Packaging in sturdy wooden crates reinforced with steel frames ensures safe delivery within a swift lead time of 7 days, making TNNPI’s High Voltage Isolation Switch an excellent choice for urgent requirements and reliable long-term installations. Whether used in commercial buildings, industrial plants, or energy infrastructure, this isolator disconnect switch guarantees secure, efficient, and durable electrical isolation solutions tailored to modern power management needs.
