Product details

Size S10 power contactor for 480 V motor circuits

The 3RT1466-2XB46-0LA2: The contactor carries an auxiliary switch and supports a 24 V DC coil with a 6 A holding current at rated voltage, so the control transformer and PLC output must be sized for that inrush.

Panel fit and mounting flexibility

Mounts via screw fixing on a vertical surface, rotatable ±90° and tiltable ±22.5° front-to-back, which helps when the gland plate or busbar layout forces an off-axis orientation.

Operating temperature and switching cycles

Maximum switching rate: 600 cycles/hour at AC-1, 350 cycles/hour at DC-1.

Frequently asked questions

What is 3RT1466-2XB46-0LA2's rated current at 480 V?

Rated 156 A at 480 V in AC-3 duty — that's the motor-switching current, not the resistive load rating. For resistive loads (AC-1), the maximum switching rate is 600 cycles/hour, but the current rating differs.
