Braking unit for SIMOVERT drives High DC voltage range (675-780V) 10KW power dissipation IP20 protection Controlled energy dissipation Industrial drive component

Product description

The Siemens 6SE7021-3FS87-2DA0 is a braking unit from the SIMOVERT MASTERDRIVES series. It is designed for operation with DC input voltages ranging from 675 to 780V and has a power rating of 10KW. The unit features an IP20 protection rating, indicating it is suitable for indoor environments where protection against solid objects greater than 12.5mm is provided.

This braking unit is essential for applications requiring controlled deceleration or stopping of motor loads, particularly in heavy-duty industrial machinery such as cranes, elevators, conveyors, and high-inertia drive systems. It dissipates excess energy generated during regenerative braking, preventing overvoltage within the drive system.

Stanlo Automation, a veteran-owned distributor of surplus industrial automation components, provides the Siemens 6SE7021-3FS87-2DA0 braking unit. We ensure you have access to reliable parts to maintain the safety and performance of your drive systems.
