Product details

The 3RT2024-2AG20: The coil connection uses spring-type terminals — no screw torque to verify on the magnet coil (cites:).

At 230 V the contactor is rated 2 hp; at 400 V the auxiliary contact is rated 3 A (cites:,).

Switching frequency by duty class — 1 000 ops/h for AC-1 through AC-3e

Maximum switching rate is 1 000 operations per hour for AC-1, AC-2, AC-3, and AC-3e duty; AC-4 duty is limited to 300 ops/h (cites:,). The arcing time is 10 ms at 50 Hz and 10 ms at 60 Hz (cites:,).

Active production — quoted to order against BOM quantities

Lifecycle stage is current production (cites:).
