Siemens 3LC5 187-1TB53 Disconnect Switch

Siemens 3LC5 187-1TB53 Disconnect Switch is a preowned, 3LC5-series disconnect device rated for 55 A at 600 VAC, engineered to provide a safe, reliable means of isolating a circuit in industrial electrical installations. As a manual disconnect, it offers a straightforward opening and closing of the circuit to prevent unintended energization during maintenance or service work, with a robust mechanical design characteristic of Siemens disconnect switches. The 187-1TB53 designation identifies this unit as a precise variant within the Siemens 3LC5 family, clarifying its model code for selection and replacement in compatible systems. Because the unit is preowned, it should be inspected for signs of wear, corrosion, or damage before reuse in any live electrical installation.
