Product details

Panel fit and physical integration

The 3RT1476-6XB46-0LA2: This Size S12 contactor measures 225 mm deep, 160 mm wide, and 214 mm tall, secured by screw fixing through a single 11 mm diameter hole.

Termination and wiring capacity

Includes an auxiliary switch for status feedback or interlocking without an add-on block.

Switching performance and ratings

Rated 192 A at 600 V and 180 A at 480 V in AC-1 duty (resistive load), making it suitable for high-current heating or lighting banks. Maximum switching frequency is 600 cycles/hour in AC-1 and 250 cycles/hour in DC-1, important for cycling loads like resistance welders or DC brakes.

Frequently asked questions

What is the AC-1 current rating of 3RT1476-6XB46-0LA2 at 600 V?

It is rated 192 A at 600 V in AC-1 duty (resistive load). At 480 V AC-1, the rating is 180 A.
