Resistor de frenagem SIMOVERT MASTERDRIVES Siemens 6SE7022-0ES87-2DC0

The 6SE7022-0ES87-2DC0 is a high-performance braking resistor engineered for the SIMOVERT MASTERDRIVES series, specifically optimized for Compact Plus drive units. This resistor is designed to dissipate the kinetic energy generated during the deceleration of industrial motors, protecting the drive’s DC link from overvoltage. It provides a nominal braking power of 12 kW and is rated for a continuous dissipation (P_perm) of 900 W, with a resistance value of 33.3 Ohm. Capable of handling peak power (P3) levels up to 18 kW, this unit is essential for applications requiring controlled, high-torque deceleration in automated production lines.

Installation Guidelines

• Thermal Clearance: Due to the heat dissipated during braking, ensure adequate clearance is maintained around the resistor to prevent thermal saturation of surrounding components.
• Ventilation: If installed within a control cabinet, verify that the cabinet has sufficient forced-air ventilation to exhaust the heat generated by the resistor.
• Wiring: Use high-temperature resistant cabling for the connections between the drive braking unit and the resistor, as terminal temperatures can reach high levels during operation.
• Placement: Position the resistor as close to the drive as possible to minimize cable inductance, while adhering to required clearance distances.
