Schneider ZB4BZ102 Single Contact Block with Body Fixing Collar
Product Overview
Main Functions
- Single-Pole Normally Closed (1NC) Switching
The contact block maintains a closed circuit in its resting state and opens when actuated by an XB4 operator head, making it ideal for stop signals, emergency interlocks, fault detection, and safety-related control functions.
- Integrated Body Fixing Collar
The built-in zinc-alloy (Zamak) collar locks the assembly to the control panel without separate hardware, ensuring a stable, anti-vibration fit for continuous operation.
- Modular Compatibility
Fully compatible with all XB4 series operator heads (push buttons, selectors, mushroom heads, pilot lights) and stackable with additional contact blocks (up to 6 poles) to create multi-circuit control solutions.
- Secure Screw-Clamp Terminals
Tool-assisted screw terminals provide high clamping force, resisting loosening from vibration or thermal cycling for maintenance-free electrical connections.
- Standard 22 mm Panel Mount
Designed for a universal 22 mm panel cutout, enabling consistent, fast installation across control panels and machinery interfaces.
