BEMKO Schelinger A02-G7-1P-C40 Miniature Circuit Breaker 1P C 40A 4.5kA

The BEMKO Schelinger A02-G7-1P-C40 is a high-quality single-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in residential and commercial environments. This device is designed to monitor current flow and automatically disconnect the circuit in the event of an overload or short circuit, thereby safeguarding wiring and connected appliances from potential damage or fire hazards.

Advantages

This circuit breaker offers robust performance and long-term reliability due to its precise manufacturing standards. The C-type tripping characteristic makes it highly versatile, as it is specifically designed to handle moderate inrush currents, which is ideal for standard lighting and power circuits. Its compact design allows for efficient use of space within distribution boards, while the 4.5kA breaking capacity ensures it can safely interrupt fault currents in typical domestic and light commercial electrical systems.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting circuits
• Protection of standard household appliances
• General purpose power outlets

When it may not be suitable

This device is not intended for industrial applications requiring higher breaking capacities or for circuits with very high starting currents, such as large industrial motors or heavy-duty machinery. It is also not suitable for DC power systems as it is specifically rated for AC electrical installations.

Key specifications

• Number of poles: 1
• Rated current: 40A
• Tripping characteristic: C-type
• Breaking capacity: 4.5kA
• System compatibility: AC power systems

How to use

The circuit breaker should be installed by a qualified electrician onto a standard DIN rail within an electrical distribution board. Ensure that the power supply is disconnected before beginning the installation. The device is snapped onto the rail and the supply wires are connected to the appropriate terminals, ensuring that all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, the switch can be toggled to the ON position to energize the circuit.

What to consider before purchase

• Verify that the 40A rating matches the requirements of your circuit load
• Ensure the C-type characteristic is appropriate for the connected devices
• Check that the 4.5kA breaking capacity meets local electrical safety standards
• Confirm compatibility with your existing DIN rail distribution board

Usage recommendations

Regularly inspect the circuit breaker for any signs of physical damage or discoloration. It is recommended to test the functionality of the breaker periodically to ensure it remains operational. If the breaker trips frequently, investigate the circuit for potential faults or overloaded conditions before resetting.
