Eaton PLSM-C20-MW Miniature Circuit Breaker, 1-Pole, C-Characteristic, 20A

The Eaton PLSM-C20-MW is a professional-grade 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is specifically designed to detect and interrupt overloads and short circuits, ensuring the safety of connected wiring and electrical appliances. With its reliable C-characteristic tripping mechanism and a 20A rated current, it serves as a critical component in modern electrical distribution boards.

Advantages

This circuit breaker offers exceptional reliability and durability, meeting stringent safety standards for electrical installations. Its modular design allows for seamless integration into standard distribution panels, facilitating quick and efficient installation. The C-characteristic ensures a balanced response to current surges, making it highly effective for protecting circuits that experience moderate inrush currents, such as those powering lighting systems or small motors.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• Small motor and appliance protection
• General purpose branch circuit protection

This device may not be suitable for industrial applications requiring high-interrupting capacity or specialized protection for sensitive electronic equipment that demands specific tripping curves. It is also not intended for use in environments with extreme moisture or corrosive atmospheres without appropriate protective enclosures.

Key specifications

• Number of poles: 1
• Rated current: 20A
• Tripping characteristic: C
• Mounting type: DIN rail
• Protection class: IP20

To install the device, ensure the power supply is disconnected. Snap the circuit breaker onto a standard 35mm DIN rail within the distribution board. Connect the incoming power supply to the top terminal and the outgoing load circuit to the bottom terminal, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 20A rating matches the requirements of your circuit wiring
• Ensure the C-characteristic is appropriate for your specific load type
• Check available space in your distribution board for a 1-pole module
• Confirm compatibility with existing DIN rail systems

For optimal performance and safety, always ensure that the circuit breaker is installed by a qualified electrician in accordance with local electrical regulations and that the wire gauge is correctly sized for a 20A load.
