Square D Company 88002 HP Class 9001 Type KA-3 Contact Block

Square D 88002 Class 9001 Type KA-3 contact block is a red, 1 normally closed (1NC) contact block designed to add a single NC contact to 30 mm push‑button assemblies in Square D’s Class 9001 line (types K, SK, and KX). It mates with 9001 KA‑series operators and uses screw‑terminal connections for secure wiring, with a maximum rating of 600 VAC (AC/DC max). The KA‑3 is commonly cataloged as part of the 88002 Series G configuration, offering a compact 30 mm footprint and an approximate mounting depth of 0.75 in (19 mm) to fit standard 30 mm operator housings. In industrial control and motor‑control panels, this block provides interlock or stop functionality by adding a dedicated normally closed contact to a control button, enabling simple, reliable circuit logic for safety and control applications.
