Siemens SENTRON 5SY4 Miniature Circuit Breaker, 2-Pole, 6 A, Type C, 400 V AC, 60 V DC, 10 kA Breaking Capacity

Look to this MCB from Siemens when you need to protect circuits near moving machinery. It reliably resists shock and vibration, so will keep working through the bumps and jolts you'd expect in heavy-duty industrial settings. You can count on the unit to shield you and two connected devices whenever its two poles receive three to five times its rated current of 6A, so it's a safe bet for demanding jobs like motor protection. Separate breaking capacities of 10kA AC and 15kA DC mean this is a dependable choice for both AC and DC currents.

• Mechanical life of 10,000 switching cycles so you can depend on it in the long term

Thanks to this MCB's temperature range of -40°C to +70°C, you can use it safely in challenging environments.
