Frequently asked questions
What is the coil voltage and main/aux contact arrangement of the 3RT2526-1BE40?
Buyers must confirm 60 V DC coil and 2 NO + 2 NC main + 1 NO + 1 NC aux match the panel design before sourcing.
What is the difference between 3RT2526-1BE40 and 3RT2526-1BE60?
The -BE40 vs -BE60 suffix changes coil voltage and is the most common cross-misorder in the 3RT25 family.
Is the 3RT2526-1BE40 still active or obsolete, and what is the lifecycle status?
Drives last-time-buy, FFF alternate search, and PCN monitoring for legacy S0 4-pole SKUs.
What are the wiring, terminal torque, and wire gauge specs for the 3RT2526-1BE40?
Panel builders and wiremen need exact screw torque, gauge, and DIN-rail mounting details for S0 build compliance.
Which motor protection breaker (3RV) coordinates with the 3RT2526-1BE40 at 11 kW / 400 V?
Required for Type 2 coordination, kAIC selection, and short-circuit discrimination in motor branch design.
What is a form-fit-function equivalent or authorized alternate for the 3RT2526-1BE40 4-pole 25A contactor?
Maintenance techs and LTB managers need a qualified substitute that preserves the 2 NO + 2 NC arrangement when stock is constrained.
