BEMKO Schelinger A02-G7-3P-B32 Miniature Circuit Breaker 3P B 32A 4.5kA AC

The BEMKO Schelinger A02-G7-3P-B32 is a high-quality 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in various environments. Designed for AC systems, this device effectively monitors current flow to prevent damage from overloads and short circuits, ensuring the safety and longevity of your electrical infrastructure.

Advantages

This circuit breaker offers robust performance and reliable operation for modern electrical installations. Its B-type tripping characteristic makes it particularly suitable for circuits with low surge currents, providing a precise response to potential faults. The compact design allows for efficient use of space within distribution boards, while the 4.5kA breaking capacity ensures that the device can safely interrupt fault currents, protecting both the wiring and connected appliances from electrical hazards.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Small-scale industrial equipment protection
• General purpose AC electrical installations

When it may not be suitable

This device is not intended for use in DC electrical systems or high-voltage industrial applications exceeding its rated specifications. It may also be unsuitable 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.

Key specifications

• Number of poles: 3
• Tripping characteristic: B
• Rated current: 32A
• Breaking capacity: 4.5kA
• System type: AC

How to use

The circuit breaker is designed for standard DIN-rail mounting within an electrical distribution panel. Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. Ensure that the supply power is disconnected before mounting the device. Once securely snapped 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 manufacturer's specified torque settings.

What to consider before purchase

• Verify that the 32A rated current matches the requirements of your circuit load.
• Ensure the B-type characteristic is appropriate for your specific application.
• Confirm that the 4.5kA breaking capacity meets the short-circuit current potential of your installation site.
• Check that your distribution board has sufficient space for a 3-pole module.

Usage recommendations

Regularly inspect the circuit breaker for signs of physical damage or overheating. It is recommended to perform a functional test of the tripping mechanism periodically to ensure continued reliability in protecting your electrical system.
