Features and benefits
• Slow break contact operation type, using standard contacts with spring clamp terminals for the connections.
• Air temperature operation ranging from -40°C to +70°C presenting you various different areas it can be used.
• Fast wiring - 3 times faster to wire saving you time and money in the long term.
• The XB4 range has a high resistance to vibration.
• Accepts stranded or solid wires with/without cable ends depending on your need:
- Wire sizes can range from 1x24 AWG/0.2mm² for cables without an end
- Wire sizes with an end can range from 1x26 AWG/1.5mm²
- No tools required to fit the cables! Fittings are standard across ZB4 & ZB5 devices (that use screw clamps).
• There is a single lever action required to open both cable clamps, limiting time unclamping several different ends, saving you time.
