Product details

The contactor is rated for 3 hp at 230 V and carries DC switching capability up to 10 A at 24 V, 2 A at 48 V, and 0.3 A at 220 V — useful for DC motor brake or solenoid loads in mixed-voltage cabinets.

Duty-cycle and switching frequency

Maximum switching frequency depends on the load duty: 1 000 operations per hour at AC-1 (resistive), 750/h at AC-2 and AC-3 (motor starting/running), 250/h at AC-4 (plugging/inching), and 750/h at AC-3e. For a conveyor or pump running continuous motor duty, the 750/h ceiling is the practical limit; the 250/h AC-4 ceiling matters only if the contactor sees frequent reversing or jogging.

Wiring and auxiliary contacts

Auxiliary switch terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²).

Frequently asked questions

What are the key switching ratings for 3RT2026-1BP40?

The contactor is rated 3 hp at 230 V AC. For DC loads it switches 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. Maximum switching frequency is 750 operations per hour for AC-3 motor duty.

What is the physical size and mounting of 3RT2026-1BP40?

It is a Size S0 contactor measuring 85 mm high, 45 mm wide, and 107 mm deep. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715.
