1sna299555r0000 – dre2,5/8,ado
TE Connectivity 1SNA299555R0000 DRE2.5/8.ADO is a grey 2.5 mm² miniature ADO feed-through terminal block with 8 mm width, 24 A IEC rated current and 1000 V rated voltage for compact industrial control wiring.
Why Choose the TE Connectivity 1SNA299555R0000 DRE2.5/8.ADO Mini Feed-Through Terminal Block?
The TE Connectivity 1SNA299555R0000, type DRE2.5/8.ADO, is a compact 2.5 mm² ADO feed-through terminal block designed for industrial control and signal wiring where panel space is restricted. Part of the Entrelec ADO miniature terminal range, it combines a space-saving format with insulation-displacement connection technology for fast and reliable conductor termination.
The DRE2.5/8.ADO is the 8 mm-wide feed-through version without the assembly rib, intended for use at the extremity of a compatible terminal strip. Two identification notches indicate its 1–2.5 mm² conductor range, while the ADO connection system supports up to two conductors per connection and avoids conventional screw-clamp termination.
With an IEC rated current of 24 A, rated voltage of 1000 V and impulse withstand voltage of 8 kV, this miniature terminal provides substantial electrical performance in a compact package. Its grey polyamide housing, IP20 main-terminal protection and TH15-5.5 DIN rail mounting make it suitable for automation, machine control and other demanding industrial installations.

Reliable ADO Connectivity for Compact Control Systems
The ADO insulation-displacement system is designed to provide fast and repeatable conductor connections without the conventional screw-clamping process. The DRE2.5/8.ADO combines this technology with an 8 mm-wide miniature housing, helping panel builders increase wiring density while maintaining a rated cross-section of 2.5 mm².
Designed for control applications exposed to demanding conditions including vibration, shock and corrosion, the DRE2.5/8.ADO provides 24 A IEC current capability and a 1000 V IEC voltage rating. Its TH15 rail mounting and extremity configuration make it particularly useful for completing compact modular terminal assemblies.
Typical Applications
- Compact industrial control panels.
- PLC and automation wiring systems.
- Machine control equipment.
- Signal and control circuits.
- Instrumentation and monitoring systems.
- Transportation electrical equipment.
- Space-constrained electrical cabinets.
- TH15 DIN rail miniature terminal assemblies.
