Schneider Electric 22 mm 2NC Contact Block
This Schneider Electric contact block is a 22 mm industrial control component rated for 10 A at 600 V AC. It uses a 2NC momentary action and screw/clamp terminals. The unit is designed for use with ZB4 or ZB5 series operators in automation panels.
Check operator series and wiring method
Verify that your existing panel uses ZB4 or ZB5 chrome or plastic operators before ordering. Confirm that the control circuit voltage does not exceed 600 V AC and that the 10 A rating matches the load. Ensure screw/clamp termination suits your wire gauge and installation practice.
Standards-backed thermal and electrical performance
The block complies with IEC 60947-1, IEC 60947-5-1, IEC 60947-5-4, UL 508, CSA C22.2 No. 14 and JIS C8201-1, C8201-5-1. These standards define temperature-rise limits and dielectric withstand for the rated 10 A, 600 V AC duty. No active cooling or fan is required in normal panel operation.

Questions about this item
Does the Schneider Electric 22 mm 2NC contact block ship with the ZB4 or ZB5 operator, or must the operator be ordered separately?
The contact block is sold alone. A compatible ZB4 or ZB5 chrome or plastic operator must be purchased separately to complete the assembly.
The block is listed as 2NC — does that mean two normally closed contacts in a single 22 mm body?
Yes, the contact form is 2NC, providing two normally closed circuits within one 22 mm block rated 10 A at 600 V AC.
What does the 10 A 600 V AC rating mean when the block is mounted on a ZB4 or ZB5 operator in a control panel?
It means each normally closed contact can switch up to 10 amperes at 600 volts AC under the NEMA A600/Q600 designation when properly installed.
