Siemens MCB, Shock Resistant, DIN Rail Mounting - Sentron Series - 5SY4310-7 To boost safety around mechanical applications involving high inrush currents, opt for this MCB from Siemens. It takes care of shutting down electrical circuits in the event of overcurrent conditions, so that's a load off your mind. As it has type C breaking characteristics, it trips when it receives three to five times its rated current of 10A. This makes it your ideal workmate for high-load industrial tasks such as starting motors or switching on fluorescent lights. Thanks to its three poles, you can use this unit to protect multiple circuits at once. Features & Benefits • Effective insulation protects you against voltage surges up to 440V AC
• Mechanical lifespan of 10,000 switching cycles, so you can count on it to last
• IP20 rating means you can touch it without risking an electric shock
• Operating temperature range between -40°C and +70°C for compatibility with harsh environments
• Snaps onto a standard 35mm DIN rail, so mounting is quick and simple What size wires can I use with this MCB? The product accepts any wire with a cross-section between 0.75 and 35mm², so you can use it with 18 to 4AWG.
