Square D's 480V277V manual motor controller is a reliable industrial component designed for 480V/277V AC applications. This 2-pole unit is part of the ABL Sursum G10 series, known for its robust manual control features. It is typically supplied in lots of two pieces, making it suitable for paired installations.
While not directly comparable to Siemens BQD390 or BQD220 circuit breakers, the 480V277V specification aligns with other industrial breakers like the GE TEY350 and Siemens BQD370. This controller is ideal for applications requiring precise manual control and is compatible with similar industrial setups.
