Schneider Electric 9001KA42 Contact Block
The Schneider Electric 9001KA42 is a 30 mm industrial contact block rated for 0.5A at 120V AC. It provides a single normally open momentary contact designed for low-energy control circuits. The black unit fits Schneider 9001K series 30 mm operators and terminates with screw-clamp connections.
Screw-clamp terminals and CSA, IEC, UL listings
The screw-clamp terminals accept solid or stranded wire without special tooling, speeding panel assembly. Compliance with CSA C22.2 No. 14, IEC 60947-1, IEC 60947-5-1, IEC 60947-5-4, JIS C4520, JIS C852 and UL 508 means the block meets North American and international safety requirements for industrial control equipment. Class II insulation to IEC 60536 adds protection against electric shock.
NEMA A600/Q600 rating for low-energy circuits
The NEMA A600/Q600 designation confirms reliable switching of 0.5A inductive or resistive loads at 120V AC, typical of pilot lights, relays and PLC inputs. The single 1NO momentary action suits start, reset or jog functions but cannot maintain a latched state or break higher currents required by motor starters or heating elements. Builders needing maintained contacts or multi-pole switching must select a different block.

Questions about this item
How often will the screw-clamp terminals on this 9001KA42 contact block need re-torquing?
The screw-clamp terminals are designed for secure, maintenance-free connections; periodic visual inspection is recommended but no scheduled re-torquing interval is specified by Schneider Electric.
What is the first limit reached when this 1NO block runs continuously at 0.5 A and 120 V AC?
The contact rating of 0.5 A at 120 V AC is the primary electrical limit; exceeding this current or voltage risks contact welding or premature wear under sustained load.
How much heat does the 30 mm block generate when carrying 0.5 A all day?
At the rated 0.5 A the block produces minimal heat; it meets Class II insulation per IEC 60536 and the A600/Q600 designation, so no active cooling is required for continuous operation.
