For all-round service, choose this motor protection circuit breaker from Siemens. When the job calls for isolation and on-off control, as well as overvoltage and overcurrent defences, it has you covered. As a Class 10 device, it trips in 10 seconds or less when it receives more than its maximum current rating of 4A. This means it acts fast to shield people and equipment. This is an especially practical pick for load-drawing applications such as motor starting where high power ratings and inrush currents can send operating temperatures soaring. Thanks to low power losses of just 6W, the breaker produces little waste heat. It handles a broad temperature range of -20°C to +60°C so you can count on it in challenging industrial conditions.

• Impulse withstand rating of 6kV means it holds its own against significant voltage surges
• Shock resistant, so safe to use in demanding settings
• 3-pole device lets you control up to 3 circuits at a time

Yes, this product has an IP20 rating, meaning its terminals are touch-safe so you don't have to worry about electric shocks.
