Bemko A02-G7-1P-B25 Miniature Circuit Breaker 1P B 25A 4.5kA AC

The Bemko A02-G7-1P-B25 is a high-quality single-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in residential and commercial environments. This device is designed to monitor current flow and automatically disconnect the power supply 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 fundamental 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 specifically optimized for general-purpose applications where moderate inrush currents are expected. The device is built to withstand standard electrical loads while maintaining a consistent performance profile over time. Its compact design allows for efficient use of space within distribution boards, and the high-quality materials used in its manufacturing ensure long-term operational stability and resistance to environmental factors common in electrical enclosures.

Suitable for

• Residential electrical distribution boards
• Commercial lighting circuits
• Protection of general-purpose power outlets
• Small-scale office electrical installations

When it may not be suitable

This circuit breaker is not intended for use in DC electrical systems, as it is specifically rated for AC applications. Furthermore, it may not be suitable for circuits with high-starting-current equipment, such as large industrial motors or heavy-duty compressors, where a C or D tripping characteristic would be required to prevent nuisance tripping.

Key specifications

• Number of poles: 1
• Tripping characteristic: B
• Rated current: 25A
• Breaking capacity: 4.5kA
• System type: AC

How to use

The device is designed for standard DIN rail mounting within a distribution cabinet. Installation should be performed by a qualified electrician in accordance with local electrical regulations. The breaker is snapped onto the rail, and the supply and load cables are secured into the terminal clamps, ensuring that all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the toggle switch can be used to manually energize or de-energize the circuit.

What to consider before purchase

• Verify that the 25A rated current matches the requirements of your specific circuit load.
• Ensure the B-type characteristic is appropriate for the connected equipment.
• Confirm that the 4.5kA breaking capacity meets the short-circuit current levels of your electrical installation.
• Check the available space in your distribution board for a single-module 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 switching mechanism periodically to ensure it remains in good working order. Do not exceed the rated current capacity to avoid premature wear or tripping.
