Industrial Contact Block
The Schneider Electric ZB4BZ104 is a 22 mm contact block with a 2NC configuration designed for industrial control panels and automation systems. It suits engineers and maintenance teams building or servicing machinery that requires reliable momentary switching.
Panel Integration
The block mounts on 22 mm cut-outs and pairs with ZB4 chrome metal operators, using screw-clamp terminals for secure wiring. It frees up panel space by combining two normally closed contacts in a single compact unit rated for 10 A at 600 V AC.
Sustained Operation
Built to IEC 60947-1, 60947-5-1, 60947-5-4 and 60947-5-5 plus CSA C22.2 No. 14, UL 508 and JIS C8201 standards, the block maintains its A600/Q600 NEMA rating under continuous industrial duty. It is not suited for applications needing normally open contacts or higher current ratings.

Questions about this item
How many amps can the 10 A @ 600 V AC contact block handle continuously?
The contact block is rated for 10 A at 600 V AC under the A600/Q600 NEMA designation, so sustained loads up to that level are within specification.
Does the screw-clamp terminal block generate noticeable heat during all-day operation?
At its rated 10 A the block operates within the thermal limits defined by IEC 60947-5-1 and UL 508, so heat rise stays low enough for continuous industrial duty.
Which 22 mm metal operators are required to mount this contact block?
It is designed for Schneider Electric ZB4 chrome metal operators, so you must already have compatible ZB4 series pushbuttons, selector switches or pilot lights.
