HLT01.1N-01M0-A-007-NNIT

The Bosch Rexroth Indramat HLT01.1N-01M0-A-007-NNIT unit is part of the HLT Braking Units Series and provides robust protection against overvoltage in industrial drive systems. Featuring a Degree of Protection: IP20 rating and designed For IT Nets, this braking chopper is optimized to dissipate excessive regenerative energy as heat, ensuring reliable operation under dynamic load conditions. Its primary function is to protect the drive converter by diverting peak currents into an external resistor during deceleration or emergency stops.

This HLT01.1N-01M0-A-007-NNIT model operates at a nominal DC voltage of 750 V, with the capability to dissipate up to 1000 kW of braking energy. The heat generated during braking is released to the surrounding air, maintaining the unit’s temperature within specified limits. The module protects against solid particles down to 12.5 mm but is not rated for liquid ingress. Installation into an enclosure with a minimum IP54 protection rating is required. Only trained personnel should mount and service the unit in the permissible orientation to ensure safety and performance.

Built for demanding industrial environments, the HLT01.1N-01M0-A-007-NNIT withstands ambient temperatures from –10 °C to +40 °C and can be stored between –25 °C and +70 °C. It offers built-in resistance to shocks and vibrations and is fully operational up to 1000 meters above sea level. The design variant for IT Nets supports modern power distribution architectures. Adhering to Bosch Rexroth’s quality standards, this braking unit enhances equipment uptime and prolongs drive component life, making it an essential asset for automated manufacturing and material handling applications.
