ABB SZ201-C10 Miniature Circuit Breaker, 1-Pole, 10A, 6kA

The ABB SZ201-C10 is a high-performance 1-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 overcurrent conditions, including overloads and short circuits, thereby safeguarding wiring and connected equipment from potential damage. With a rated current of 10A and a 6kA breaking capacity, it offers a reliable solution for maintaining the integrity and safety of electrical distribution systems.

Advantages

This miniature circuit breaker stands out due to its high manufacturing standards and consistent performance under varying electrical loads. The C-curve tripping characteristic makes it particularly versatile for general applications where moderate inrush currents are expected. Its compact design allows for efficient use of space within distribution boards, while the robust construction ensures long-term operational stability and durability in demanding electrical installations.

Suitable for

• Residential electrical distribution boards
• Commercial lighting and power circuits
• Protection of small appliances and office equipment
• General purpose branch circuit protection

When it may not be suitable

This device is not intended for use in circuits requiring higher current ratings than 10A or in systems where the prospective short-circuit current exceeds 6kA. It is also not suitable for DC applications unless specifically rated for such use, as this model is designed for standard AC electrical systems.

Key specifications

• Number of poles: 1
• Rated current: 10A
• Breaking capacity: 6kA
• Tripping characteristic: C-curve
• Mounting type: DIN rail

How to use

The circuit breaker should be installed by a qualified electrician in accordance with local electrical codes and safety regulations. It is designed for mounting onto a standard DIN rail within a distribution enclosure. Ensure that the supply wires are correctly terminated to the input terminals and that the load wires are connected to the output terminals, maintaining proper torque settings as specified by the manufacturer to ensure secure electrical contact.

What to consider before purchase

• Verify that the 10A rating matches the requirements of your specific circuit load.
• Ensure the 6kA breaking capacity is sufficient for the prospective fault current at the installation point.
• Confirm that the C-curve characteristic is appropriate for the type of equipment being protected.
• Check the available space in your distribution board for a 1-pole module.

Usage recommendations

Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to perform periodic testing of the installation to ensure that the protection device remains functional and that all electrical connections remain tight and free from corrosion.
