Overview
The Lenze ERBM082R100W brake resistor is a fixed resistor designed for dissipating regenerative braking energy in inverter-driven motion control systems. With an aluminum profile housing mounted next to the inverter and connected via a ready-made connecting cable with integrated thermal contact for temperature monitoring, this unit protects variable frequency drives from DC-bus overvoltage during rapid motor deceleration.
Key Features
- Aluminum profile housing design for reliable heat dissipation
- Integrated thermal contact for temperature monitoring to prevent thermal runaway
- Ready-made connecting cable for simplified integration
- Switches on when DC-bus voltage exceeds threshold, preventing overvoltage fault and drive coasting
- Rated 82 Ohm / 100W for compact industrial applications
Technical Specifications
The ERBM082R100W delivers precise braking energy dissipation in regenerative drive applications where motors must decelerate rapidly or hold loads on inclines.
Typical Applications
- Lenze AC Tech and modern Lenze drive systems (i500, i550, 8400, 9400 series)
- Variable frequency drives requiring regenerative braking
- Industrial automation systems with frequent dynamic braking cycles
- Material handling, conveyor, and crane applications
- Renewable energy systems with energy recovery requirements
Compatibility & Replacements
Compatible With
- Lenze inverter drives (all series with brake chopper support)
- Lenze i500 and i550 servo drives

Replaces / Drop-In Replacement For
Verify specific replacement compatibility with Lenze documentation or your system integrator, as brake resistor selection depends on drive model, motor inertia, and braking cycle duty cycle. Contact technical support with your inverter model and application parameters for exact cross-references.
Works With
- Lenze DSD (Drive Selection and Design) Engineering Tool for resistor selection
- External brake chopper modules (30% continuous braking power rating per cULus standards)
- Temperature monitoring relays and safety interlocks
- Standard industrial motor control cabinets and panel layouts
