Product details

96 A AC-3 at 480 V — the headline rating that decides the motor load

The 3RT2047-1AB04 is a SIRIUS power contactor rated 96 A at 480 V in AC-3 duty — that is the current it can switch motor loads under the standard IEC 60947-4-1 utilization category, covering starting and disconnecting of squirrel-cage motors during running. Size S3 frame, 140 mm high, 70 mm wide, 195 mm deep — the depth is the dimension that matters most when the panel depth is tight, especially with the required 20 mm forward clearance for arc quenching.

Mounting and wiring — DIN rail snap-on with screw terminals

Snaps onto 35 mm standard mounting rail per DIN EN 60715, with screw-type terminals on the magnet coil and main contacts — the main contact wiring accepts stranded 6 to 70 mm², solid 2.5 to 16 mm², or two smaller conductors per clamp. Mounting position is flexible: ±180° rotation on a vertical surface, plus ±22.5° tilt forward/backward — useful when the contactor sits on a swing frame or angled subpanel.

Lifecycle and sourcing — active production, quoted to order

No stock-holding claim; sourced per RFQ from authorized supply.

Frequently asked questions

What is the 3RT2047-1AB04 used for?

It is a power contactor for switching three-phase motor loads up to 96 A in AC-3 duty at 480 V, typically in motor control centers, conveyor drives, pump panels, and compressor starters.
