Compact circuit breaker LS TS1250N NG5 1250A 3P

LS TS1250N NG5 1250A 3P compact circuit breaker is a reliable protective element designed to protect electrical installations and devices from overloads and short circuits. It is a key component in power distribution systems, ensuring safety and continuity of supply.

Characteristics and application

This circuit breaker, with a rated current of 1250A, is designed to operate in AC networks with a voltage of up to 690V. Its three-pole design (3P) makes it ideal for protecting three-phase circuits. The NG5 release, equipped with normal operating functions, provides effective protection without the need for additional communication. This makes the circuit breaker easy to install and operate while offering a high level of safety.

LS TS1250N compact circuit breakers are used in a wide range of facilities – from commercial and industrial buildings to critical infrastructure. They are suitable for anywhere where reliable protection against the effects of electrical failures is required.

Parameters and capabilities

The LS TS1250N NG5 1250A 3P circuit breaker is characterized by a high short-circuit breaking capacity (Icu) of 50kA at 380/415V AC and 35kA at 660/690V AC. This means that it is able to effectively interrupt even strong short-circuit currents, minimizing the risk of damage to the installation and danger to people. The Ics value (short-circuit making capacity) is 100% Icu, which confirms its reliability in real-world operating conditions.

The electronic release provides comprehensive protection:

• L – protection against overload (long-term).
• S – protection against short-circuit (short-term).
• I – protection against instantaneous short-circuit.

Additionally, the circuit breaker has protection against earth fault (G), which increases the safety of the entire system. The ability to adjust the rated current allows for precise adaptation of the circuit breaker characteristics to the specific needs of the installation.

Construction and mounting

The LS TS1250N NG5 1250A 3P circuit breaker is distinguished by its solid construction and high quality of workmanship. Connection of wires is made using screws on the front terminals, which facilitates the installation and disassembly of the device. Compact dimensions (210 x 327 x 152.5 mm) allow for installation in limited space. The circuit breaker meets IP30 standard, which provides protection against accidental contact and against the influence of solid objects larger than 2.5 mm. Designed to operate in temperatures from -20°C to +70°C.
