The B6-22-00-80 is a 4-pole mini contactor rated 20 A at 690 VAC with a 240 VAC coil, carrying 2 normally open and 2 normally closed auxiliary contacts on screw terminals. Surface-mount form factor — no DIN-rail clip, so it bolts directly to a panel or subplate.
Panel fit — what the surface mount means
Surface mount means no DIN-rail adapter — you drill and tap the panel or use a mounting plate. The screw terminals accept up to 4 mm² stranded or solid copper. Coil draws roughly 5–8 VA inrush, 2–3 VA sealed at 240 VAC; verify your control transformer has headroom if you're switching multiple contactors from the same 240 VAC circuit.
