This is a miniature circuit breaker (MCB) designed for optimal protection in electrical installations. With three poles and a current rating of 6A, it ensures reliable performance. The MCB operates effectively at rated AC voltages of 230V and 400V.

Features & Benefits

• Type C MCB allows for medium inrush currents

• 10kA breaking capacity ensures effective short-circuit protection

• Thermal tripping mechanism supports overload prevention

• Electromechanical tripping enhances operational reliability

• Compact DIN rail mount design simplifies installation

• Screw terminal connections provide secure wiring options

Applications

• Ideal for protecting lighting and heating circuits

• For socket outlets servicing household appliances

Is it easy to install in existing systems?

Yes, it features a compact DIN rail mount design.

How does the thermal element provide overload protection?

The thermal element heats up with excess current, activating the breaker to protect the circuit from overloads.
