Product details

The 3RT2326-2BG40: Mechanical endurance is quoted at 10,000,000 typical cycles — that figure assumes the contactor is switching rated load within its utilisation category, not dry-circuit or stalled-motor duty.

Mounting position and wiring capacity — planning the enclosure layout

The auxiliary switch is included, with two attachable auxiliary contact blocks possible — the auxiliary wiring uses the same spring-cage terminals as the coil. If the panel ambient near the contactor exceeds 60 °C — say, above a drive heatsink or near a steam line — you need to derate or relocate.

Sourcing and lifecycle — active production, quoted to order

A panel specified around those parts cannot drop in the 3RT2326-2BG40 without a full wiring review.

Frequently asked questions

What are the DC switching ratings for the 3RT2326-2BG40?

These are the steady-state holding currents for the DC coil.

How can I order the 3RT2326-2BG40 or check availability?

The contactor is sourced to order against the BOM through independent distribution channels.
