The ABB B7-30-01-84 is a 3-pole contactor rated for 16 A at 600 VAC, with a 110-120 VAC control coil.
The 16 A rating applies to the main power contacts; at 600 VAC it handles typical three-phase motor loads up to roughly 7.5 kW (per IEC 60947-4-1 AC-3 duty), though the exact motor rating depends on the load type and duty cycle. The 3-pole configuration switches all three phases simultaneously, which is standard for three-phase motors or resistive heater banks. The 110-120 VAC coil is a common control voltage in North American panels; verify the control transformer matches before wiring.
Panel Integration
DIN rail mounting means it clips onto a standard 35 mm rail inside the enclosure. The contactor occupies a single modular width; leave clearance for the coil terminals and any auxiliary contact block added alongside.
