It is designed for control-circuit switching in motor starter and contactor assemblies, typically mounted alongside a main contactor to add signal feedback or interlocking.
Rated operational current at AC-12 (resistive control loads) is 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 1 A at 690 V. These are the actual switching limits for the four NO contacts — use the AC-12 curve, not a motor-contactor rating, when sizing this auxiliary block. The contactor accepts solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², or 2x 4 mm² per terminal, which covers typical control wiring.
