Bemko A02-G8-3P-B20 Miniature Circuit Breaker 3P B 20A 6kA AC

The Bemko A02-G8-3P-B20 is a high-quality 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in various environments. This device is specifically designed to monitor and safeguard electrical installations by automatically disconnecting the power supply in the event of an overload or a short circuit, thereby preventing potential damage to wiring and connected equipment. With its robust construction and precise engineering, it serves as a critical component for maintaining safety and operational continuity in modern electrical systems.

Advantages

This miniature circuit breaker offers exceptional reliability and performance for AC electrical systems. Its B-type tripping characteristic ensures a balanced response to current surges, making it highly effective for standard residential and commercial lighting or heating circuits. The 6kA breaking capacity provides a sufficient safety margin for handling fault currents, while the 3-pole configuration allows for the simultaneous protection of three-phase power lines, ensuring comprehensive coverage for complex electrical setups.

Suitable for

• Residential electrical distribution boards
• Commercial office building power circuits
• Protection of lighting systems
• General purpose heating and appliance circuits

When it may not be suitable

This circuit breaker is not intended for use in DC electrical systems or high-voltage industrial applications that require higher breaking capacities. It is also not suitable for circuits with high inrush currents, such as those powering large motors, where a C or D-type tripping characteristic would be required instead of the B-type.

Key specifications

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

How to use

The device is designed for standard DIN rail mounting within an electrical distribution cabinet. Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The wires should be securely connected to the terminals, ensuring proper torque is applied to prevent loose connections. Once installed, the breaker can be manually toggled to the ON position to energize the circuit, and it will automatically trip to the OFF position if a fault is detected.

What to consider before purchase

• Verify that the 20A rated current matches the requirements of your specific circuit load.
• Ensure the 3-pole configuration is compatible with your three-phase electrical installation.
• Confirm that the B-type tripping characteristic is appropriate for the types of devices connected to the circuit.
• Check the available space in your distribution board for a 3-module wide device.

Usage recommendations: Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform a functional test of the tripping mechanism periodically to ensure the device remains in optimal working condition.
