R. STAHL 8530/1-MCB-STA102-B16-000-2 Miniature Circuit Breaker
Components for system solutions
Model: 8530/1-MCB-STA102-B16-000-2
Art. No.: 293918
Product Type: MCB Miniature circuit breaker
The R. STAHL 8530 series miniature circuit breakers are overcurrent devices offering excellent current limiting for short circuits and high switching capacity (10, 15, or 25 kA). They provide a low load on cables and high selectivity for upstream fuses. These components feature a modular design and are available in 1- to 4-pole versions for rated currents of 0.5-63 A. The maximum installation capacity is 4.5 subunits.
Key Features:
- Isolation function in accordance with EN60947-2
- Energy limitation class 3
- Modular design for simple replacement or expansion of systems
- Easy installation: snaps onto the mounting rail in Ex e enclosures
- Non-adjustable thermal and magnetic releases
- Ergonomically shaped operating lever for safe switching on and off
- Padlocks (Accessories) provide protection against being switched on again during maintenance work
