Bemko A02-G8-3P-C25 Miniature Circuit Breaker 3P C 25A 6kA AC

The Bemko A02-G8-3P-C25 is a high-quality 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits. Designed for AC systems, this device effectively monitors current flow to prevent damage from overloads and short circuits. With its robust construction and precise engineering, it serves as a critical safety component in modern electrical distribution boards, ensuring the longevity and security of connected equipment.

Advantages

This miniature circuit breaker offers exceptional reliability through its C-type tripping characteristic, which is specifically calibrated to handle standard inductive and resistive loads. The 6kA breaking capacity ensures that the device can safely interrupt high fault currents, providing a significant safety margin for residential and commercial installations. Its 3-pole configuration allows for the simultaneous disconnection of three phases, making it an ideal choice for three-phase power systems where balanced protection is required.

Suitable for

• Residential electrical distribution boards
• Commercial building power systems
• Three-phase motor protection
• General lighting and appliance circuits
• Industrial control panels

When it may not be suitable

This device is not intended for use in DC electrical systems, as its internal mechanism is specifically designed for AC current characteristics. Furthermore, it should not be used in environments where the expected short-circuit current exceeds 6kA, as this would surpass the device's rated breaking capacity and compromise safety.

Key specifications

• Number of poles: 3
• Rated current: 25A
• Tripping characteristic: C-type
• Breaking capacity: 6kA
• System compatibility: AC

How to use

The circuit breaker is designed for standard DIN-rail mounting within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical regulations. Ensure that the supply power is disconnected before mounting the device. Once securely clipped onto the DIN rail, connect the incoming power lines to the top terminals and the outgoing load lines to the bottom terminals, ensuring all connections are tightened to the specified torque to prevent overheating.

What to consider before purchase

• Verify that the 25A rated current matches the requirements of your electrical circuit.
• Ensure the 6kA breaking capacity is sufficient for the prospective short-circuit current at the installation point.
• Confirm that your system is a 3-phase AC configuration.
• Check the available space in your distribution board for a 3-pole module.

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 smooth operation. If the breaker trips, investigate the cause of the overload or short circuit before resetting the switch.
