Frequently asked questions
What is the coil voltage of the Siemens 3RT2526-1BJ80 contactor?
Buyers must match the 72 V DC coil to their control circuit before committing to purchase.
What are the main and auxiliary contact configurations of the 3RT2526-1BJ80?
The 2 NO + 2 NC main and 1 NO + 1 NC auxiliary contacts determine if it fits the motor wiring scheme.
What is the difference between 3RT2526-1BJ80 and other 3RT2526 variants?
Only the coil suffix (e.g., 1BJ80 vs 1BB40) differs across the family, and picking the wrong coil wastes lead time and budget.
How much does the Siemens 3RT2526-1BJ80 cost?
Pricing variance between authorized distributors and brokers drives sourcing decisions for spares and new builds.
Where can I buy the Siemens 3RT2526-1BJ80 contactor?
Buyers need confirmed stock from authorized channels to avoid counterfeit or obsolete risk.
What cross-reference equivalents exist for the 3RT2526-1BJ80?
Identifies alternates when lead times spike or the MPN is allocated, critical for MRO spares continuity.
