M22 1NC Contact Block

Numer katalogowy: M22 - K01
Eaton M22 Seria Introduced circa 2000

Eaton M22 series 1NC contact block.

Typowe Zastosowania

1NC contact block for stop and safety circuits. The NC contact breaks the circuit when pressed — fail-safe design. Wire in series with motor contactor coil. Keep spares on hand — contact blocks are the most common failure point.

Kompatybilność

Same compatibility as M22-K10. NC version. Fits all M22 operators.

Naprawa i Konserwacja

NC contacts are safety-critical — replace every 5 years as preventive maintenance on e-stop circuits regardless of test results.

Skrócona Instrukcja Montażu

Mounting: Snap onto the rear of any compatible button body in the same series. The latch clicks audibly when properly seated. Some models require a mounting adapter.

Wiring: Terminals are marked NO (11/12) or NC (21/22). Use 0.5-2.5mm² wire with ferrules. Tighten to 0.8 Nm. Verify with a multimeter before energizing.

Rozwiązywanie Problemów

Intermittent switching

Silver contacts are pitted from arcing. Replace the contact block — they are consumable parts. If arcing is severe, check that the switched load doesn't exceed the contact rating (typically 6A at 120VAC).

Contact block won't snap onto button body

Verify the contact block series matches the button head series (e.g., Schneider ZB4 blocks fit ZB4 heads only, not ZB5). Check for debris or damage on the mounting tabs.
