Harmony XB4 Contact Block for Industrial Panels
This Schneider Electric ZB4BZ1025 is a pre-assembled contact block and fixing collar designed for Harmony XB4 push-button heads. It provides one normally closed contact and carries an IP20 rating to protect operators from live parts. The metal body weighs 49 g and operates from -40 °C to 70 °C.
Suits Builders Completing XB4 Stations
Electricians finishing Harmony XB4 control stations will appreciate the push-in terminals and the 1 million cycle endurance that reduces maintenance. Installers who need normally open contacts, multiple contact blocks in one collar, or a different mounting diameter should look at other configurations.
Simple Push-In Installation
The block snaps onto a 22 mm cut-out and the push-in terminals accept solid or ferruled wires without tools. The most common issue is exceeding the single NC contact rating or using a head not designed for the XB4 collar, which prevents a secure lock.

Questions about this item
Which Harmony XB4 operator head do I need to complete the 22 mm metal body assembly?
Any Harmony XB4 head — push button, selector switch, pilot light or mushroom — clips onto the pre-assembled collar to finish the 22 mm unit.
Can the push-in terminals on this 1 NC contact block accept solid and stranded wire without ferrules?
Yes, the push-in terminals are designed for direct insertion of both solid and stranded conductors, no ferrules required.
How do I verify the IP20 protection and NC contact operation after wiring the block?
Confirm the IP20 finger-safe shroud covers all live parts, then use a continuity tester to prove the circuit opens when the operator is actuated.
