Industrial Contact Block 22 mm 10 A 600 V
This Schneider Electric contact block provides a single normally-closed circuit rated at 10 amperes and 600 volts AC. It mounts in a standard 22 mm panel cut-out and is designed for use with chrome ZB4 metal operators. The screw-clamp terminals accept wire without special tools, and the momentary action suits push-button or selector-switch applications. It carries CSA, IEC, JIS and UL 508 listings for industrial control panels.
Passive Component Thermal and Power Profile
As a passive electromechanical device the block generates no measurable heat and operates silently in normal service. Power draw is limited to the contact circuit itself, so no additional cooling or power-budget allowance is required. The screw-clamp terminals maintain a secure connection under vibration without loosening. Compliance with IEC 60947-5-1 and UL 508 confirms suitability for continuous industrial duty.
Standards-Driven Integration Benefits
Certification to CSA C22.2 No. 14, IEC 60947-1, IEC 60947-5-1, IEC 60947-5-4, IEC 60947-5-5, JIS C8201-1, JIS C8201-5-1 and UL 508 allows the block to be specified in panels that must meet North American and international codes. The A600/Q600 NEMA designation simplifies contactor and relay coordination. Buyers needing normally-open contacts or multiple poles will require additional blocks.

Questions about this item
How do you mount the 22 mm contact block onto a panel and what step is often missed?
Insert the block through a 22 mm cut-out, align the anti-rotation notch, then tighten the locking nut; the step often missed is engaging the notch before final torque.
What maintenance or replacement will the screw-clamp terminals need over time?
Periodically re-tighten the screw clamps to counter vibration loosening and inspect contacts for pitting; replace the block if contact resistance rises or the 1NC action fails.
At what current does the 10 A 600 V AC rating become the limiting factor during sustained operation?
Continuous loads above 10 A at 600 V AC will exceed the A600/Q600 rating, causing overheating and premature contact wear.
