ABB AL26-30-10 Auxiliary Contact Block for AL26 Series Contactor

The ABB AL26-30-10 Auxiliary Contact Block for AL26 Series Contactor extends control signaling in industrial automation by adding an auxiliary contact to a standard AL26 device. It provides 3 normally open main contacts and 1 normally open auxiliary contact, with a DC-operated coil rated at 24 VDC (variant dependent) and a rated operational voltage up to 690 V AC / 220 V DC. The unit is designed for DIN rail or panel mounting and uses screw terminals, supporting a rated current of ~26 A at 400 V (AC-3). It is commonly used in motor control centers, conveyor systems, HVAC equipment, industrial machinery, and automation schemes where interlocking and status indication are required. Common replacements include ABB AL26-30-01, ABB AF26 series contactors, and Schneider LC1D25.
