ABB SZ201-C16 Miniature Circuit Breaker, 1-Pole, 16A, 6kA

The ABB SZ201-C16 is a professional-grade 1-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits. Designed for both residential and commercial applications, this device effectively monitors current flow to prevent damage from overloads and short circuits. With a 16A rated current and a 6kA breaking capacity, it serves as a critical component in modern power distribution systems, ensuring that electrical installations remain safe and operational under varying load conditions.

Advantages

This miniature circuit breaker stands out due to its robust construction and high reliability in demanding electrical environments. The C-curve characteristic allows for versatile use, providing a balanced response to both standard and slightly higher inrush currents. Its compact 1-pole design facilitates easy installation in standard distribution boards, while the high-quality materials used by ABB ensure long-term durability and consistent performance, minimizing the risk of nuisance tripping and enhancing overall system safety.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of standard household appliances
• Small-scale industrial control panels

When it may not be suitable

This device is not intended for high-power industrial machinery that requires a different tripping characteristic or higher breaking capacity. It is also not suitable for direct current (DC) applications unless specifically rated for such use, as this model is designed for standard alternating current (AC) systems.

Key specifications

• Number of poles: 1
• Rated current: 16A
• 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 regulations. It is designed to be mounted onto a standard DIN rail within a distribution enclosure. Once securely snapped into place, the input and output cables are connected to the respective terminals. Ensure that all connections are tightened to the manufacturer's specified torque to prevent overheating. After installation, the device can be manually switched on or off using the toggle lever on the front.

What to consider before purchase

• Verify that the 16A rating matches your circuit requirements
• Ensure the C-curve characteristic is appropriate for your connected loads
• Check available space in your distribution board for a 1-pole module
• Confirm compatibility with your existing DIN rail system

Usage recommendations

Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to test the functionality of the device periodically to ensure it remains in good working order. Do not attempt to modify or repair the internal mechanism, as this will void safety certifications and compromise protection.
