03.38.13N-34CU

The 03.38.13N-34CU is a high-performance spring set brake from KEB’s Combistop Spring Brakes series, designed for reliable torque control in industrial automation environments. This compact unit, designated as Type 38 with Size 03, engages automatically when power is removed and disengages upon power application, ensuring safe holding of rotational inertias. Weighing just 1.8 kg (Mass: 1.8 kg), the brake features a zinc-plated housing (Zinc plating: Yes) for corrosion resistance and durability. The brake carries CE marking (Marking: CE) and TÜV approval, underscoring compliance with international safety and quality standards.

Featuring an electromagnetic-actuated dual-surface design, the brake applies force via high-tension springs (Hand Release: Yes) and neutralizes braking torque with electromagnetic excitation. It offers an adjustable braking torque range, allowing precise tuning through clearance adjustment, while steel drive discs with pressure-bonded lining material deliver consistent friction performance. The unit is rated for 100% continuous duty (Duty: 100%) in dry operation and includes connection cables for straightforward integration. With a nominal operating temperature of 0 to 40 °C (Operating Temperature: 0 to 40 °C), it maintains stable performance under standard industrial conditions.

Operational features include IP20 protection (Protection Class: IP20), which can be upgraded to IP44 with an optional dust-protection ring, safeguarding internal components from particulate ingress. The dual-surface configuration ensures uniform wear between spring-applied and electromagnetic surfaces, extending maintenance intervals. An integrated hand release provides manual disengagement for setup and emergency purposes, while the steel drive disc construction minimizes thermal deformation under load. KEB recommends installation by trained technical personnel only, with maintenance performed after complete stop to ensure personnel safety and prevent torque loss when operating near extreme temperature limits.

The 03.38.13N-34CU brake seamlessly integrates into crane systems, stacking equipment, gate drives, and driverless transport vehicles requiring precise holding and stopping functions. Its compact Size 03 form factor and standardized connection cables facilitate straightforward retrofits and new installations. Offering TÜV-approved safety, CE certification, and upgraded protection options, this Combistop Spring Brake is ideal for industrial applications demanding robust, maintenance-friendly torque control solutions.
