Product Description
Benefits & Applications
The Schneider Electric ZBE102 is a durable 1NC (Normally Closed) auxiliary contact block designed for use with Schneider’s TeSys D contactors and Harmony XB4/XB5 industrial pushbutton operators. Known for high electrical reliability and long mechanical life, the ZBE102 is widely used in control panels, motor starters, interlock circuits, and automation equipment where dependable auxiliary signaling is essential.
With its snap-on mounting design, the ZBE102 installs quickly on the front or side of compatible devices, allowing panel builders and technicians to expand control logic without modifying the primary power circuit. It is ideal for stop functions, safety interlocks, and PLC input logic requiring a normally closed signal.
Typical Applications
- Motor starter auxiliary signaling
- Stop and safety interlock circuits
- PLC and automation feedback inputs
- Control panels, MCCs, and OEM equipment
- Harmony XB4/XB5 pushbutton stations
Technical Advantages
- 1 Normally Closed (1NC) auxiliary contact for safety and stop circuits
- High electrical endurance for industrial switching environments
- Fast, tool-free snap-on installation
- Compatible with TeSys D contactors (LC1D series)
- Works with Harmony XB4/XB5 switches and operator heads
- Compact, modular design ideal for dense control panel layouts
Compatibility Notes
The ZBE102 integrates seamlessly with Schneider Electric’s TeSys and Harmony platforms, including:
- TeSys D contactors: LC1D09 – LC1D38
- LC1K miniature contactors (with adaptor)
- Harmony XB4 metal operator heads
- Harmony XB5 plastic operator heads
- TeSys D motor starters using LRD overload relays
If your application requires a 1NC auxiliary contact for a Schneider pushbutton, selector switch, or contactor, the ZBE102 is the correct OEM replacement.
Frequently Asked Questions
Q: What does “1NC” mean for the ZBE102?
“1NC” means the contact is Normally Closed and opens when the operator or device is actuated. This is commonly used for stop, safety, and interlock functions.
Q: Which Schneider contactors does the ZBE102 fit?
It fits the LC1D TeSys D contactor series (09–38 amps) and can also be used with LC1K miniature contactors when an adapter is added.
Q: Is the ZBE102 compatible with Harmony pushbuttons?
Yes. It works with XB4 metal and XB5 plastic operator heads, including pushbuttons, selector switches, and pilot devices.
Q: Can multiple ZBE102 contacts be stacked?
Yes. You can stack additional ZBE102 (NC) and ZBE101 (NO) blocks to create multi-contact configurations.
Q: What is the difference between ZBE101 and ZBE102?
ZBE101 = 1NO (Normally Open) auxiliary contact.
ZBE102 = 1NC (Normally Closed) auxiliary contact.
