Schelinger A02-G7-3P-B10 Miniature Circuit Breaker 3P B 10A 4.5kA AC

The Schelinger A02-G7-3P-B10 is a high-quality 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in both residential and commercial environments. This device is specifically designed to monitor current flow and automatically disconnect power in the event of an overload or short circuit, thereby preventing damage to wiring and connected appliances. With its robust construction and precise tripping mechanism, it serves as a critical component for maintaining the safety and integrity of modern electrical distribution systems.

Advantages

This miniature circuit breaker offers exceptional reliability through its B-type tripping characteristic, which is optimized for general-purpose applications with low surge currents. The 3-pole configuration allows for the simultaneous protection of three-phase circuits, ensuring balanced operation and comprehensive safety. Its compact design facilitates easy installation in standard distribution boards, while the 4.5kA breaking capacity provides sufficient protection against typical short-circuit faults encountered in standard electrical installations.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of three-phase electrical appliances
• General electrical infrastructure maintenance

When it may not be suitable

This device is not intended for use in high-power industrial environments where fault currents may exceed 4.5kA. It is also not suitable for circuits with high inrush currents, such as those powering large motors or transformers, where a C or D-type tripping characteristic would be required instead of the B-type provided here.

Key specifications

• Number of poles: 3
• Tripping characteristic: B
• Rated current: 10A
• Breaking capacity: 4.5kA
• System type: AC

How to use

The circuit breaker should be installed by a qualified electrician onto a standard DIN rail within a distribution enclosure. Ensure that the supply cables are securely connected to the input terminals and the load cables to the output terminals, following the wiring diagram provided on the device. Once installed, the toggle switch can be moved to the 'ON' position to energize the circuit. If the breaker trips, investigate the cause of the overload or short circuit before resetting the switch.

What to consider before purchase

• Verify that the 10A rated current matches the requirements of your specific circuit load.
• Ensure the 4.5kA breaking capacity is sufficient for the prospective fault current at the installation point.
• Confirm that your electrical system requires a 3-pole configuration.
• Check compatibility with your existing distribution board and DIN rail mounting system.

Usage recommendations

Always ensure that the power supply is completely disconnected before attempting any installation or maintenance work on the circuit breaker to prevent the risk of electric shock.
