50 Series Miniature Circuit Breakers

Product catalog summary

Overview: The 50 Series Miniature Circuit Breakers (MCBs) by Werner Elektrik are designed for reliable protection against overload and short circuit faults. They are available in single to four-pole versions with current ratings from 2 to 63 Amps and breaking capacities of 3, 4.5, 6, and 10 kA.

Specifications: These MCBs feature uniform switching capacity across B, C, and D tripping curves, are compact, DIN mountable, and have a high mechanical and electrical lifespan. Terminals are finger-touch proof for safety.

Technical Data: Operating at 240/415 VAC and 48 VDC, with a frequency of 50 to 60 Hz, they have a rated impulse withstand voltage of 4000 V. They function in temperatures from -5 to +50°C and offer IP20 protection for terminals and IP40 for the enclosure.

Model Number Structure: Model numbers indicate breaking capacity, number of poles, tripping curve, and current rating, e.g., 50.03.32.63 for a 3 kA, 3 poles, C curve, 63 A rating.

Temperature Characteristics: MCBs maintain load capacity across various temperatures, with specific diversity factors for configurations.

Let-through Properties: Detailed graphs and data illustrate let-through energy and current characteristics for B, C, and D curves under fault conditions.

Auxiliary Options: MCBs can include auxiliary contacts, trip indicators, under-voltage releases, and shunt release blocks for enhanced functionality.

Application Considerations: Not recommended for life or property risk applications without proper rating and installation. Third-party certification documents are available upon request.

Disclaimers and Warranty: Werner disclaims responsibility for code conformity, user programming, and indirect damages. A one-year warranty covers defects if products are properly stored, installed, and maintained.

Terms and Conditions: Specifications may change without notice. Customers should consult Werner representatives for clarifications.
