For reliable switching of your industrial motors, go for this contactor from Siemens. It has 3NO contacts and provides operating power to the connected load when it's energised. As an AC-3 unit, it's a practical choice for setups that don't have current-limiting devices in the circuit. The thermoplastic housing offers protection from mechanical impact and abrasion, making it suitable for use in rugged industrial settings. It also has an IP20 rating, which means it can withstand objects larger than 12.5mm in size, including your fingers. This component is commonly found in the transportation industry.

• Surge voltage resistance rating of 6kV to handle power spikes without damage
• Current rating of 55A for use in heavy-duty motor applications
• Mechanical service life of 10,000,000 operating cycles for long-term performance
• DIN rail mounting is simple and tool-free, saving time and effort
• Low power loss of 4W per pole for energy efficiency

Yes, this contactor's thermoplastic body is flame-retardant and stops burning in a short time in the event of a fire, so it can help reduce the spread of flames.
