Eaton PL6-B20/3 Miniature Circuit Breaker, 3-Pole, B-Curve, 20A, 6kA

The Eaton PL6-B20/3 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in residential and commercial environments. This device is designed to monitor current flow and automatically disconnect the power supply in the event of an overload or short circuit, thereby preventing damage to wiring and connected equipment. With its reliable B-curve tripping characteristic and a 6kA breaking capacity, it serves as a critical component for maintaining electrical safety in AC power systems.

Advantages

This circuit breaker offers exceptional reliability and durability, meeting stringent industry standards for electrical protection. Its 3-pole configuration allows for the simultaneous disconnection of three phases, making it highly effective for protecting three-phase circuits and equipment. The B-curve characteristic is specifically optimized for applications where low-level short-circuit currents are expected, ensuring precise and timely tripping. Furthermore, the compact design facilitates easy installation in standard distribution boards, saving valuable space while ensuring high performance and long-term operational stability.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of three-phase electrical appliances
• General purpose AC circuit protection

This device may not be suitable for industrial applications requiring high-level surge protection or environments with extreme ambient temperatures outside the specified operating range. It is also not intended for DC power systems, as it is specifically designed for AC electrical installations.

Key specifications

• Number of poles: 3
• Rated current: 20A
• Tripping characteristic: B-curve
• Breaking capacity: 6kA
• System type: AC

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed to be mounted onto a standard DIN rail within an enclosure. Ensure that the supply voltage and current requirements of your circuit match the specifications of the breaker before connection. Once mounted, verify that all terminal connections are tightened securely to prevent overheating.

What to consider before purchase

• Verify that the 20A rating is appropriate for the load of your specific circuit
• Ensure the 3-pole configuration matches your electrical system requirements
• Check that the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point
• Confirm compatibility with your existing distribution board and DIN rail system

For optimal safety and performance, regularly inspect the circuit breaker for signs of wear or damage and ensure that the distribution board remains free of dust and moisture. Do not attempt to modify or repair the internal mechanism of the device.
