ASEA AL16-40-00 Direct Current Contactor

The ASEA AL16-40-00-81 is a four-pole, 24 V DC coil contactor from ABB's AL series, designed for reliable DC-controlled switching in industrial control panels. It uses four normally open main contacts (4NO) and a 24 V DC coil, with a nominal current rating of 30 A. The -81 suffix denotes the 24 V DC coil option within the AL16-40-00 family. The unit weighs about 2.0 lb, reflecting its compact footprint for space-constrained installations. For performance, catalog data lists a 15 hp rating at 550–600 VAC and a lower-voltage equivalence, illustrating its suitability for motor and load switching in automated equipment. This direct current contactor is manufactured by ABB (formerly ASEA Brown Boveri) and aligns with ABB/ASEA control gear for integration in standard industrial control systems.
