The Schelinger A02-G7-3P-C16 is a high-quality 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in both residential and commercial environments. This device is specifically designed to safeguard electrical installations against the risks of overloads and short circuits, ensuring the long-term operational stability of connected equipment and wiring systems. With its precise engineering, it serves as a critical component in modern electrical distribution boards, offering reliable performance in AC power systems.

Advantages

This miniature circuit breaker stands out due to its reliable tripping mechanism and durable construction, which contribute to enhanced safety in electrical networks. Its C-type characteristic makes it versatile for various applications, effectively managing moderate inrush currents without unnecessary tripping. The compact 3-pole design allows for efficient space utilization within distribution panels, while the 4.5kA breaking capacity provides sufficient protection for standard electrical circuits, ensuring that faults are isolated quickly and effectively to prevent damage to the infrastructure.

Suitable for

• Residential electrical distribution boards
• Commercial office building power circuits
• Protection of lighting and general-purpose socket circuits
• Small industrial machinery and equipment installations

When it may not be suitable

This circuit breaker is not intended for use in high-power industrial environments where fault currents exceed 4.5kA. It is also not suitable for DC electrical systems, as it is specifically designed for AC applications.

Key specifications

• Number of poles: 3
• Rated current: 16A
• Tripping characteristic: C-type
• Breaking capacity: 4.5kA
• System compatibility: AC

How to use

The device is designed for standard DIN-rail mounting within an electrical distribution enclosure. Installation should be performed by a qualified electrician to ensure all connections are secure and compliant with local electrical regulations. The breaker is snapped onto the rail, and the supply and load wires are connected to the respective terminals, ensuring that the torque specifications are followed to prevent loose connections.

What to consider before purchase

• Verify that the 16A rated current matches the requirements of your circuit load.
• Ensure the 4.5kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Confirm that the 3-pole configuration is appropriate for your specific electrical system layout.

Usage recommendations

Regular inspection of the circuit breaker is recommended to ensure that all terminal connections remain tight and free from signs of overheating. If the breaker trips, investigate the cause of the overload or short circuit before resetting the switch.
