ABB SZ201-B10 Miniature Circuit Breaker, 1-Pole, B-Curve, 10A, 6kA

The ABB SZ201-B10 is a professional-grade 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in residential and commercial environments. This device is designed to detect and interrupt overcurrents and short circuits, ensuring the safety of connected appliances and wiring systems. With its compact design and reliable performance, it serves as a critical component in modern AC power distribution boards, maintaining operational stability and preventing potential electrical hazards.

Advantages

This miniature circuit breaker offers high reliability due to its precise B-curve tripping characteristic, which is optimized for general applications with low surge currents. The 6kA breaking capacity ensures that the device can safely handle significant fault currents, providing a high level of protection for your electrical infrastructure. Its 1-pole configuration allows for efficient space utilization in distribution panels, while the ABB build quality guarantees long-term durability and consistent performance under standard operating conditions.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• General purpose power outlets
• Protection of resistive loads

This circuit breaker may not be suitable for applications involving high inrush currents, such as large motors or transformers, where a C-curve or D-curve characteristic would be required to prevent nuisance tripping. It is also not intended for DC power systems or environments exceeding its rated voltage and current specifications.

Key specifications

• Number of poles: 1
• Rated current: 10A
• Tripping characteristic: B-curve
• Breaking capacity: 6kA
• System voltage: AC

Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is designed for mounting on a standard DIN rail within an enclosure. Ensure that the supply power is disconnected before beginning the installation process. Secure the wires firmly into the terminals, ensuring proper contact to prevent overheating during operation.

What to consider before purchase

• Verify that the 10A rating matches your circuit load requirements
• Ensure the B-curve characteristic is appropriate for your specific equipment
• Check compatibility with your existing DIN rail distribution board
• Confirm the breaking capacity meets local safety standards for your installation

For optimal safety and longevity, regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to test the functionality of the breaker periodically to ensure it remains responsive to fault conditions.
