Description
The Siemens 1250A, 3-pole switch disconnector (Frame Size 5) is a heavy-duty, premium isolation device engineered for high-demand low-voltage power distribution networks. Part of the robust Siemens industrial portfolio (typically the SENTRON series), this component is designed to safely make, carry, and break nominal currents under load, ensuring maximum operational safety and system reliability during maintenance or emergency procedures.
Key Specifications & Features:Current Rating: 1250 A, built for high-capacity industrial applications and machinery.
Configuration: 3-Pole (3P) architecture for standard three-phase electrical systems.
Connection Type: Flat terminal design, allowing for secure, low-resistance connections directly to busbars or heavy-duty cable lugs.
Frame Size: Size 5, offering an optimized footprint that balances a compact form factor with the necessary dielectric strength for high-amperage routing.
Operational Safety: Delivers a high short-circuit withstand capacity and reliable isolation gaps, effectively protecting personnel and downstream equipment.
