Compact circuit breaker LS TS250N FMU 200A 3P

Compact power switch – reliable installation protection

This three-pole LS TS250N FMU 200A compact switch is a key protection element in every electrical installation. It provides effective protection against overloads and short circuits, guaranteeing the safety of devices and people. It is a solid solution for both professional installers and end-users looking for reliable protection.

Construction and application

The TS250N FMU 200A switch is designed to operate in AC networks up to 690V and DC up to 500V. Its construction based on high-quality materials ensures long-lasting and trouble-free operation. The thermal release with adjustment allows you to adapt the switch characteristics to the specifics of the protected circuit, and the non-adjustable short-circuit release provides a quick response in the event of a short circuit. This makes the device perfect for protecting various loads, from electric motors to lighting and sockets.

Key features and benefits

• High breaking capacity: Short-circuit breaking capacity up to 50 kA at 400V guarantees effective protection even in the event of large short-circuit currents. This translates to minimizing the risk of damage to the installation and equipment.
• Adjustable thermal release: The ability to adjust the thermal release tripping threshold (in the range of 200-250A) allows for precise adjustment of the protection characteristics to the load, avoiding unnecessary tripping.
• Durable construction: Made of high-quality materials and a solid construction ensure a long service life – confirmed by mechanical endurance of 25,000 cycles and electrical endurance of 10,000 cycles at 415 VAC.
• Compact dimensions: Dimensions of 105 x 160 x 86 mm allow for easy mounting in switchboards with limited space.
• Compliance with standards: Compliance with IEC60947-2 standard guarantees the safety and reliability of the device.
• Versatile connections: The ability to connect wires both from the front and the back of the switch simplifies installation and configuration.

Technical parameters in practice

The TS250N FMU 200A switch is characterized by a rated current of 250A, making it an ideal choice for circuits with higher power demand. The rated operating voltage Ue is AC: 690 V and DC: 500 V, which provides a wide range of applications. It is worth paying attention to the high short-circuit breaking capacity (Icu) of up to 100 kA at 220/240 V, which is crucial for ensuring the safety of the installation in the event of a failure.
