Why Choose the Original WAGO 280-905
- Tool-free wiring via CAGE CLAMP® technology — reduces installation time by up to 50% vs. screw terminals
- Vibration-resistant spring-clamp connection — ideal for mobile machinery and harsh environments
- Proven reliability in millions of global installations across industrial automation, building technology, and energy sectors
- Compact footprint — maximizes DIN rail density in space-constrained panels
- Full compliance with IEC, UL, and CSA standards — simplifies certification of end equipment
- Long service life — no re-tightening required, unlike screw terminals subject to thermal cycling
Typical Applications
- Industrial control panels and switchgear
- PLC I/O wiring and field device termination
- Machine building and OEM automation systems
- Building automation (HVAC, lighting, access control)
- Power distribution and energy management panels
- Railway and transportation control systems
- Process instrumentation and sensor wiring
System Compatibility
- DIN Rail: EN 60715 / DIN 35 — standard 35 mm rail, compatible with all major DIN rail systems
- Conductor Types: Solid, stranded, and fine-stranded wire (with ferrule)
- Accessories: Compatible with WAGO 280-series end stops, partition plates, and marking systems
- Adjacent Terminals: Can be combined with WAGO 280-series ground, fuse, and disconnect terminals for integrated terminal strip assemblies
- PLC Brands: Siemens, Allen-Bradley (Rockwell), Mitsubishi, Omron, Schneider Electric, ABB — all standard DIN rail panel builds
Selection Guide
Use the following criteria to confirm the WAGO 280-905 is the right terminal block for your application, or to select an appropriate alternative:
- Conductor cross-section: If your wire gauge is 0.08–4 mm² (AWG 28–12), the 280-905 is a direct fit. For larger conductors (6–16 mm²), consider WAGO 285 or 286 series.
- Rated current: 16 A is suitable for most control circuit wiring. For power circuits above 16 A, select a higher-rated terminal (e.g., WAGO 285-series or Phoenix Contact UK 6).
- Connection method: CAGE CLAMP® (tool-free) is preferred for high-vibration or high-cycle environments. If screw terminals are required by specification, see equivalent screw-type models above.
- Environment: IP20 is suitable for enclosed panels. For outdoor or wash-down environments, consider IP-rated enclosure solutions.
- Quantity / Pack size: Confirm pack quantity (unit vs. box) when ordering — the 280-905 is typically sold in packs of 50 or 100 units.
- Certifications required: UL 508 listed for North American markets; IEC 60947-7-1 for international/EU applications.

Replacement & Compatibility FAQ
Q: Can I replace WAGO 280-905 with Phoenix Contact UK 4 N directly?
A: In most control panel applications, yes — both are 4 mm² DIN rail feed-through terminals. Verify rated current (UK 4 N is rated 32 A vs. 16 A for 280-905) and physical width before substitution in tight assemblies.
Q: Is the WAGO 280-905 compatible with ferrule-terminated wires?
A: Yes. CAGE CLAMP® accepts fine-stranded wire with or without ferrules. Ferrules are recommended for fine-stranded conductors to ensure reliable contact.
Q: What is the difference between WAGO 280-905 and WAGO 281-905?
A: The 281 series uses a lever-actuated PUSH WIRE® connection instead of CAGE CLAMP®. Both accept similar conductor ranges but differ in actuation method — 281 series is preferred for very frequent re-wiring scenarios.
Q: Can WAGO 280-905 be used in UL-listed panels in North America?
A: Yes. The 280-905 carries UL 508 listing and is suitable for use in UL-listed industrial control panels.
Q: Are spare parts and accessories available?
A: Yes — WAGO 280-series accessories including end stops (280-301), partition plates, and test plugs are available. Contact us for a complete accessories list.
