Choose this two-pole MCB from Eaton to stand guard against excess current. In the event of an overload or short circuit, this 4A unit de-energises your system in a flash to prevent costly faults and equipment failures. Type D characteristics mean it trips when it receives three to five times its current rating. When supplied with 400V AC, it breaks currents up to 15kA, so it's just the thing for your high-powered electrical systems. Compact dimensions of 85 (W) x 36 (L) x 73mm (D) mean that it doesn't take up a lot of space on your DIN rail. You'll find units like this one doing duty in process control, industrial automation and electric engineering applications.

• IP20 rating assures you it's touch-proof and protected against objects larger than 12mm
• DIN-rail mounting to ensure a simple, speedy setup
• Rated impulse withstand voltage of 4kV for extra protection from electrical damage
• Contact position indicator allows for easy status monitoring

This MCB works reliably in temperatures between -40°C and +75°C, so it's just the thing for use in harsh work areas.
