192 A three-pole switching with built-in auxiliaries
The ABB A210-30-11-84 is a 3-pole across-the-line contactor rated at 192 A, with a 120 V AC control coil and factory-fitted 1 NO + 1 NC auxiliary contacts. For a panel OEM wiring a motor starter, the 192 A continuous rating sets the load ceiling for three-phase motor or resistive loads — the contactor itself does not provide overload protection, so pair it with a separate thermal or electronic overload relay sized to the motor FLA.
Copper current path and auxiliary wiring
Copper conductors, two per pole, handle the main current path — the material choice avoids the thermal cycling fatigue of aluminium terminations in high-cycle motor starts. The integrated 1 NO + 1 NC auxiliary contacts eliminate a separate add-on block for basic status feedback or interlocking, saving DIN rail space in a crowded panel.
