The device offers an Ics of 25kA at 380/415V AC and an Icu of 36kA at 220/230V AC, ensuring robust performance in industrial and commercial power distribution systems. It is rated IP20 for indoor installation.

## Long description

The Kanlux KMCCB-RT-125A is a high-performance 3-pole molded case circuit breaker (MCCB) engineered to provide reliable protection for electrical circuits in demanding environments. This device is specifically designed to manage power distribution effectively, featuring a rated current of 125A and an adjustable thermal release mechanism that allows for precise calibration according to specific load requirements. With its robust construction and high breaking capacity, it serves as a critical component for maintaining safety and operational continuity in industrial and commercial electrical installations.
Advantages
The primary advantage of this circuit breaker lies in its adjustable thermal release, which offers flexibility in protecting various types of electrical equipment by allowing the user to fine-tune the trip settings. Its high short-circuit breaking capacity ensures that the device can safely interrupt significant fault currents, thereby preventing damage to downstream infrastructure. The 3-pole configuration makes it ideal for standard three-phase power systems, providing a compact and durable solution that meets professional standards for electrical safety and reliability.
Suitable for
Industrial power distribution panels
Commercial building electrical systems
Protection of three-phase motors and machinery
Main circuit protection in sub-distribution boards
When it may not be suitable
This device is not intended for outdoor use or environments exposed to moisture, dust, or extreme weather conditions, as it carries an IP20 ingress protection rating. It is also not suitable for applications requiring single-pole protection or specialized DC circuit management.
Key specifications
Number of poles: 3
Rated current: 125A
Service short-circuit breaking capacity (Ics): 25kA at 380/415V AC
Ultimate short-circuit breaking capacity (Icu): 36kA at 220/230V AC
Ingress protection: IP20
Release type: Adjustable thermal
How to use
The Kanlux KMCCB-RT-125A should be installed by a qualified electrician within a suitable electrical enclosure. The device is designed for mounting on a flat surface or within a distribution board. Before installation, ensure that the power supply is disconnected. Connect the input and output cables to the corresponding terminals, ensuring that all connections are tightened to the manufacturer's specified torque. Once installed, the thermal release can be adjusted using the integrated control dial to match the specific current requirements of the protected circuit.
What to consider before purchase
Verify that the rated current of 125A matches your circuit load requirements.
Ensure the installation environment is dry and protected, meeting the IP20 rating.
Confirm that the breaking capacity (Ics/Icu) is sufficient for the prospective short-circuit current at the installation point.
Check the available space in your distribution board for a 3-pole MCCB unit.
Usage recommendations
Always perform a final inspection of all terminal connections after installation to prevent overheating. Regularly test the circuit breaker functionality according to local electrical safety regulations to ensure long-term reliability.
