Sentron Load Break Switch 3LD5 UL, Emergency Stop Switch, 3-pole, approved according to UL489, UL60947-4-1, and IEC60947-3, UL: 60A, SCCR 50kA at 480VAC, operational capacity at 480VAC 3-phase: 40hp, IEC: 63A, operational capacity at AC-23A at 400V: 30kW, floor mounting with door coupling, bypassable rotary drive, emergency stop, 4-hole mounting of the handle, without tolerance compensation, including terminal covers for the supply side. The main and emergency stop switch 3LD ensures safe disconnection of loads in various environments. The applications of the 3LD3 network disconnection devices are diverse. After network disconnections, they ensure the safe isolation of the entire electrical equipment and can switch off three-phase motors as well as air conditioning and ventilation systems. The 3LD3 are also ideally suited for use in control or switch cabinets, particularly for applications in small machines such as saws, compressors, pumps, concrete mixers, drills, milling machines, and woodworking machines. The Siemens main and emergency stop switches 3LD are characterized primarily by: 1. Modular design, quick and easy installation of auxiliary switches, N-PE terminal or 4th pole. 2. Versatile applicability thanks to local approvals. 3. A mechanical size for five electrical sizes. 4. Suitability for DC applications. 5. Mounting types: front mounting, mounting plate, DIN rail. 6. Optimal network disconnection from 16 A to 63 A through the lockable rotary drive.
