Working Principles

The KLKR02.5T operates based on the principle of thermal-magnetic protection. It utilizes a bimetallic strip for thermal protection and a magnetic coil for instantaneous short-circuit protection. When the current exceeds the rated value, the bimetallic strip deflects, causing the contacts to open and interrupt the circuit.

Detailed Application Field Plans

The KLKR02.5T circuit breaker finds extensive application in residential, commercial, and industrial electrical installations. It is commonly used for protecting lighting circuits, power outlets, and control circuits from overcurrent conditions. Additionally, it is suitable for use in motor protection applications where a low-rated current is required.

Detailed and Complete Alternative Models

• Model 1: KLK03T
  • Rated Current: 3A
  • Voltage Rating: Up to 415V AC
  • Breaking Capacity: 6kA
• Model 2: KLKR06T
  • Rated Current: 6A
  • Voltage Rating: Up to 240V AC
  • Breaking Capacity: 10kA

In conclusion, the KLKR02.5T circuit breaker offers reliable overcurrent protection in low voltage electrical systems, making it a crucial component in various applications. Its compact design, quick trip response, and compatibility with DIN rail mounting make it a preferred choice for many electrical installations.
