Product details

Termination and wiring

The 3RT2024-2AL20-ZX95: Coil connection uses spring-type terminals — no screw tightening needed, which speeds up panel wiring and eliminates periodic retorquing on vibrating machinery.

Duty cycle and switching frequency

Rated for 1,000 operating cycles per hour in AC-1, AC-2, AC-3, and AC-3e duty; drops to 300 cycles per hour in AC-4 (plugging/inching) — the thermal load of frequent reversing limits the rate.

Environmental limits and endurance

Mechanical life 10 million operations typical — the contactor will outlast most machines it controls if the electrical load stays within the AC-3 rating.

Frequently asked questions

What compliance documentation does Siemens provide for 3RT2024-2AL20-ZX95?

The evidence does not list specific compliance certificates (RoHS, REACH, UL, IEC) for this order code. Standard SIRIUS contactors carry CE, UL, and CSA markings per the series datasheet; confirm the exact declaration with the supplier at RFQ time.
