Product Description
Benefits & Applications
The Schneider Electric ZBE101 is a high-quality 1NO (normally open) auxiliary contact block designed for use with a wide range of TeSys D contactors, motor starters, and XB4/XB5 pushbutton operators. Built for industrial reliability, the ZBE101 provides dependable auxiliary signaling for control circuits, interlocks, and status indication in commercial and industrial electrical systems.
Its snap-on design makes installation fast and secure, allowing panel builders and maintenance teams to expand existing control logic without rewiring the main power circuit. The ZBE101 is widely used in motor control centers, HVAC equipment, automated machinery, and OEM control panels.
Typical Applications
- Auxiliary signaling for motor starters and contactors
- Interlock circuits and PLC inputs
- Start/stop pushbutton stations
- Control panels and MCCs
- HVAC equipment and building automation systems
Technical Advantages
- 1 Normally Open (1NO) contact for auxiliary control circuits
- Quick, tool-free mounting on Schneider TeSys contactors
- Long electrical and mechanical endurance
- High-quality silver alloy contacts for reliable signal transfer
- Compatible with pushbutton operators and selector switches
- Compact footprint optimized for tight panel designs
Compatibility Notes
The ZBE101 is part of Schneider Electric’s TeSys and Harmony accessory ecosystem. It is compatible with:
- TeSys D contactors (LC1D09–LC1D38 frames)
- LC1K miniature contactors (with adaptor)
- Harmony XB4 / XB5 pushbutton operators
- Motor starters using LRD overload relays
If your system uses a Schneider TeSys D contactor or Harmony control operator, the ZBE101 is the standard 1NO auxiliary contact block for expanding control logic.
Frequently Asked Questions
Q: What does “1NO” mean for the ZBE101?
“1NO” means the contact is normally open. It closes only when the device (contactor, relay, or button)is operated.
Q: Which Schneider contactors does the ZBE101 fit?
It fits most TeSys D LC1D-series contactors from LC1D09 through LC1D38. It also fits Harmony XB4/XB5 operators and can be used with LC1K miniature contactors when an adapter is used.
Q: Can I stack multiple ZBE101 contacts?
Yes. Multiple auxiliary blocks can be stacked to increase the number of NO/NC contacts needed for your control logic.
Q: What is the difference between ZBE101 and ZBE102?
The ZBE101 is a 1NO auxiliary contact. The ZBE102 is a 1NC auxiliary contact. Both can be combined for NO/NC configurations.
Q: Is the ZBE101 suitable for PLC input circuits?
Yes. Its silver-alloy contacts provide clean, reliable signaling for PLCs and automation systems.
