Product details

It fastens via screw and snap-on mounting onto 35 mm standard mounting rail per DIN EN 60715, and the mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° tilt forward and backward — useful when fitting into a crowded panel where the rail orientation isn't ideal.

The contactor accepts solid conductors from 2.5 to 16 mm² and stranded from 6 to 70 mm², so it covers a wide range of motor feeder sizes without needing terminal adapters.

Switching rates: up to 900 operations per hour at AC-1 (resistive loads), 400 at AC-2, 1,000 at AC-3 (standard motor starting), and 300 at AC-4 (plugging/inching).

Frequently asked questions

How do I get current pricing and availability for 3RT2045-1AN60?

Submit an RFQ. We source and quote to order through independent distribution; availability and current pricing are confirmed at quote time. No stock or price figures are published here.

What is the depth of 3RT2045-1AN60?

The depth is 152 mm. That's the dimension from the mounting surface to the furthest projection — critical when panel depth is limited.

What conductor sizes does 3RT2045-1AN60 accept?

Solid conductors from 2.5 to 16 mm² and stranded from 6 to 70 mm². The screw-type terminals handle a wide range without adapters.
