Product information

Description

The ABB SZ203-B20 is a high-quality 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in various environments. This device is designed to monitor current flow and automatically disconnect power in the event of an overload or short circuit, thereby safeguarding electrical infrastructure and connected equipment from damage. With its robust construction and precise tripping mechanism, it ensures consistent performance and safety in AC power distribution systems.

Advantages

This circuit breaker offers exceptional reliability due to its advanced B-curve tripping characteristic, which is specifically optimized for applications where low-level short-circuit protection is required. Its 3-pole configuration allows for the simultaneous protection of three-phase circuits, making it a versatile component for modern electrical panels. The 6kA breaking capacity provides sufficient headroom for typical residential and light commercial fault conditions, ensuring that the device can safely interrupt high currents without failure. Furthermore, the compact design facilitates easy installation in standard distribution boards, saving valuable space while maintaining high safety standards.

Suitable for

  • Residential electrical distribution boards
  • Commercial building power systems
  • Protection of lighting circuits
  • General-purpose three-phase electrical installations

This device may not be suitable for industrial applications requiring higher breaking capacities exceeding 6kA or for circuits with high inrush currents that might cause nuisance tripping with a B-curve characteristic. It is also not intended for use in DC power systems unless specifically rated for such applications.

Key specifications

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

To install the ABB SZ203-B20, ensure the main power supply is disconnected. The device is designed for mounting onto a standard DIN rail within an electrical enclosure. Secure the breaker firmly onto the rail and connect the incoming and outgoing supply cables to the appropriate terminals, ensuring that all connections are tightened to the manufacturer's specified torque settings to prevent overheating. Once installed, verify the wiring and restore power to test the circuit functionality.

What to consider before purchase

  • Verify that the 20A rating matches the requirements of your circuit load
  • Ensure the B-curve characteristic is appropriate for your specific equipment
  • Confirm that the 6kA breaking capacity meets local electrical safety standards
  • Check the available space in your distribution board for a 3-pole device
Always consult with a qualified electrician to ensure that the circuit breaker is correctly sized and installed in accordance with local electrical codes and safety regulations.
