Compact circuit breaker LS TD160NA DSU 160A 3P

Compact LS Electric Disconnector – Reliable Installation Protection

The LS Electric TD160NA DSU compact disconnector is a three-pole device designed for manual switching of electrical circuits on and off. It is a key element ensuring safety in industrial and commercial installations, as well as in public buildings. The design of this disconnector combines solidity, reliability and compact dimensions, making it easy to install even in limited spaces.

Application and design features

The TD160NA DSU 160A 3P disconnector is used wherever manual disconnection of circuits with a rated current of up to 160A is required. Thanks to its high short-circuit strength of 50 kA (for Ue = 400V) and the ability to operate in direct current circuits (up to 500V DC), it is a versatile solution for various applications. Made of high-quality materials, it ensures long-lasting and trouble-free operation. The lever mechanism allows for quick and reliable switching of the circuit.

• Rated current: 160A – ensures safe operation for loads with appropriate power.
• Three-pole design: allows disconnection of all phases simultaneously, increasing safety during maintenance and repairs.
• High short-circuit strength (Icu = 50 kA / 400V): guarantees protection against the effects of short circuits, minimizing the risk of damage to installations and equipment.
• Possibility of operation in DC circuits: expands the range of applications, allowing use in installations powered by direct current.
• Mechanical durability (25,000 operations) and electrical durability (10,000 operations): ensures long device life and minimizes operating costs.
• Protection degree IP20 (IP40 with additional covers): protects against contact and the influence of solid bodies, and in the case of using additional covers – also against splashing water.
• Rated insulation voltage Ui: 750V – ensures safe operation in installations with higher voltage.

Installation and compliance with standards

The LS TD160NA DSU disconnector complies with IEC60947-2 standard, which confirms its safety and reliability. Installation is simple and intuitive, which translates into time savings during installation. Compact dimensions (90x140x86 mm) allow for easy adaptation to existing electrical infrastructure. The device is manufactured by the renowned company Aniro Sp. z o.o., which guarantees high quality workmanship and availability of technical service. The weight of the device is only 1.5 kg, which facilitates transport and installation.
