Product details

What this SIRIUS contactor is and what it switches

The 3RT6026-1AF00: The contactor is rated for a maximum AC-3 operating voltage of 690 V and carries an insulation voltage rating of 690 V, matching the common 400/690 V industrial supply.

Switching frequency and service life

Switching frequency depends on the duty cycle: AC-1 (resistive loads) allows up to 1,000 operations per hour, AC-3 (motor starting) allows 750 per hour, and AC-4 (plugging/inching) allows 250 per hour. The electrical switching frequency at AC-3e is also 750 operations per hour maximum, consistent with standard motor-starting duty.

Environmental and compliance specs

Pollution degree 3 means it tolerates conductive dust and humidity typical of factory floors. The contactor meets RoHS substance prohibitions per the 05/01/2012 compliance date.
