Product details

What is the 3RT2526-2AF00?

It carries a 110 V 50 Hz coil with spring-type terminals on the coil side, and includes a built-in auxiliary switch block (1 NO + 1 NC).

Coil voltage and frequency — what the 110 V 50 Hz rating means

The coil is rated for 110 V at 50 Hz, drawing 10 A at the rated value. At 60 Hz the coil impedance shifts, so this variant is specified for 50 Hz networks only — if your line runs 60 Hz, the 3RT2526-2AF00 is not the correct coil tap. The spring-type coil terminals accept 2x (0.5... 2.5 mm²) solid or stranded wire, which simplifies wiring in panels where screw terminals are being phased out for vibration-resistant connections.

The 3RT2526-2AF00 is at a current-production lifecycle stage, meaning it remains in active manufacture and supply. No official successor has been issued, and the part is still the standard offering for this coil voltage and frame size.
