## Long description

The Eaton PLSM B20/3-MW is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is designed to detect and interrupt overcurrents, effectively preventing damage to wiring and connected equipment caused by overloads or short circuits. With its precise B-curve tripping characteristic and a 20A rated current, it offers a reliable solution for maintaining the integrity and safety of modern electrical distribution systems.
Advantages
This circuit breaker stands out due to its high breaking capacity of 10kA, which ensures reliable performance even under demanding electrical conditions. The 3-pole configuration allows for the simultaneous disconnection of three phases, providing comprehensive protection for three-phase systems. Its compact design facilitates easy installation in standard distribution boards, while the high-quality construction materials ensure long-term operational stability and durability in various environmental conditions.
Suitable for
Protection of three-phase electrical circuits in residential buildings
Safeguarding commercial lighting and power distribution systems
Integration into industrial control panels for machinery protection
General electrical installations requiring reliable overload and short-circuit defense
This device may not be suitable for applications requiring a different tripping characteristic, such as C or D curves, which are better suited for high-inrush current loads like large motors or transformers. Additionally, it is designed specifically for AC systems and should not be used in DC circuits unless explicitly rated for such use.
Key specifications
Number of poles: 3
Rated current: 20A
Tripping characteristic: B-curve
Breaking capacity: 10kA
System compatibility: AC
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a distribution enclosure. Ensure that the supply voltage and load requirements match the specifications of the breaker before connecting the conductors. Securely tighten all terminal connections to prevent overheating and ensure optimal electrical contact.
What to consider before purchase
Verify that the 20A rating is appropriate for the specific circuit load
Ensure the B-curve characteristic matches the type of connected equipment
Confirm that the 3-pole configuration is required for your electrical system
Check available space in your distribution board for installation
For optimal safety and longevity, regularly inspect the circuit breaker for signs of wear or thermal damage and ensure that the distribution board remains free of dust and moisture.
