Product Description
Schneider Electric ZBE101 Contact Block — 1 N.O., Harmony XB4 / ZB4
The Schneider Electric ZBE101 is a single-pole, normally open (1 N.O.) contact block from the Harmony XB4 / ZB4 series, designed for front-mounting on Schneider Electric 22mm pilot device operators including pushbuttons, selector switches, emergency stop devices, and pilot lights. Featuring screw clamp terminals and a snap-fit construction, the ZBE101 is the standard N.O. contact block for Harmony ZB4 and XB4 panel-mount operators in industrial and commercial control applications.

Product Features
- Universal XB4 / ZB4 Compatibility: Snaps directly onto any Schneider Electric Harmony ZB4 or XB4 22mm operator without tools. Multiple ZBE101 blocks can be stacked on a single operator to add additional N.O. contacts as required by the circuit.
- Screw Clamp Terminals: Accepts rigid or flexible conductors for secure, tool-based wiring. Terminals are clearly marked for fast, accurate installation.
- Slow-Break Contact Action: The 1 N.O. slow-break contact provides reliable circuit switching for standard industrial control applications including motor start circuits, PLC inputs, and signalling.
- High Endurance: Rated for millions of mechanical operations, suitable for demanding industrial environments with frequent switching cycles.
- Global Certifications: Fully compliant with IEC, CE, UL, and CSA standards for domestic and international panel builds.

Frequently Asked Questions
What does ZBE101 mean?
The ZBE101 follows Schneider Electric’s Harmony naming convention: ZB = Harmony ZB4 series contact block body, E = contact element type, 1 = 1 normally open (N.O.) contact, 01 = standard slow-break action. It is the most commonly ordered contact block for Harmony XB4 and ZB4 operators and is the correct block for adding a single N.O. contact to any 22mm Harmony pilot device.
What is the difference between ZBE101 and ZBE102?
The ZBE101 provides 1 normally open (N.O.) contact and the ZBE102 provides 1 normally closed (N.C.) contact. Both are front-mount slow-break blocks compatible with the same Harmony ZB4 and XB4 operators. Choose ZBE101 for circuits that need to close when the operator is actuated (e.g., a motor start button), and ZBE102 for circuits that need to open when the operator is actuated (e.g., an interlock or stop circuit).
How many ZBE101 blocks can be stacked on one operator?
Up to 3 contact blocks (ZBE101, ZBE102, or a combination) can typically be stacked on a single Harmony ZB4 or XB4 operator, depending on the operator body depth and panel cutout. When stacking more than one block, a ZB4BZ009 fixing collar is required to secure the assembly into the 22mm panel hole. Check the specific operator’s datasheet for the maximum stacking configuration.
Is the ZBE101 compatible with XB5 series operators?
Yes — the ZBE101 is compatible with Schneider Electric’s XB5 series operators in addition to XB4 and ZB4. All three series use the same 22mm mounting format and the same Harmony contact block interface. If you are building a panel with a mix of XB4 and XB5 operators, a single ZBE101 stock covers contact block requirements across all of them.
What wire sizes are compatible with the ZBE101 terminals?
The ZBE101 screw clamp terminals accept rigid conductors from 0.5mm² to 4mm² (AWG 20 to AWG 12) and flexible conductors from 0.5mm² to 2.5mm² (AWG 20 to AWG 14). For flexible wire, ferrules are recommended for the most secure connection. Tighten terminals to the torque specification in the product datasheet to avoid loose connections under vibration.
