Reliable motor protection – ETI MS18-6.3A circuit breaker

The MS18-6.3A motor circuit breaker is a solid and proven solution for protecting electric motors against overloads and short circuits. The device, manufactured by the renowned company ETI Polam, combines functionality, reliability and ease of installation. Thanks to its three poles and thermal-magnetic tripping characteristics, it provides effective protection in demanding working conditions.

Functionality and application

The MS18-6.3A circuit breaker is used in electrical installations powering motors with a power of up to 2.5 kW (AC-3, 400V). It can also be used as a main or emergency switch in electrical circuits. Phase failure sensitivity is an additional advantage, increasing the safety of the installation. Frame clamps facilitate connection of wires, and the adjustable overload trip setting range (4-6.3A) allows the device to be adapted to specific needs.

Key features and benefits

• Wide range of operating voltages: The ability to use it in installations with a voltage of 230V to 690V provides flexibility and versatility.
• High short-circuit breaking capacity: The rated short-circuit breaking capacity of 50 kA at 400V AC guarantees effective protection against the effects of sudden voltage surges.
• Thermal protection: Built-in thermal protection protects the motor from overheating, extending its lifespan.
• Fixed mounting: The device's design for fixed mounting ensures stability and reliable operation.
• Phase failure sensitivity: This function minimizes the risk of damage to the motor in the event of loss of one of the supply phases.
• Adjustable current range: Allows precise adjustment of protection to the characteristics of the load (4-6.3A).
• Solid construction: Made of high-quality materials, ensuring durability and resistance to mechanical damage.

The MS18-6.3A circuit breaker is an optimal choice for both professional installers and end-users looking for a reliable and effective solution for protecting electric motors. The device meets safety standards and is characterized by easy installation and intuitive operation. The IP20 protection class indicates that it is intended for use indoors, in dry places not exposed to direct atmospheric influences.
