⚡ Key Features

2 NO (normally-open) contacts for load switching and sequencing; 2 NC (normally-closed) contacts for interlocking, fail-safe, and alarm circuits — all contacts independently switchable up to the contact voltage rating.
220–230V AC coil — energises from PLC digital output (transistor or relay type), timer contact, or pushbutton; no separate relay driver card required.
Contact voltage rating 690V AC — switches 230V AC loads (solenoid valves, motor starters, indicator lamps) and DC loads (PLC inputs, LED panels) within the same contact rating.
TeSys K control relay — identical DIN rail footprint to TeSys D contactors; accepts LA1KN auxiliary contact blocks for additional NO/NC outputs; mountable on 35mm or 20mm DIN rail.
Manufactured to IEC 60947-5-1 — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified, CE marked, RoHS compliant — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Schneider Electric product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.

❓ Frequently Asked Questions

Q: The CA2KN22M7 has a coil voltage of 220–230V AC — what control supply is needed?

A: This Schneider Electric device requires a 220–230V AC control supply connected to the coil terminals (A1 and A2). For AC coils, ensure the control circuit voltage is stable — voltage drops below 85% of rated coil voltage can cause chatter and coil overheating. Always fit a surge suppressor across the coil when switching with a PLC or solid-state relay.

Q: What circuit can the 2 NO + 2 NC contacts of the CA2KN22M7 switch at 690V AC?

A: The 2 NO + 2 NC contacts on the CA2KN22M7 are rated for switching at up to 690V AC. These auxiliary contacts are typically used for: (1) indication lamps and buzzers, (2) PLC input feedback to confirm device state, (3) interlocking with other contactors or relays in control circuits. Check the current rating of the auxiliary contact (typically 10A at 250V AC) — do not use for power load switching.

Q: How do I test the CA2KN22M7 relay in the field without a signal source?

A: Most Schneider Electric relays can be manually forced using the test button (if fitted) — this mechanically closes the relay contacts without energising the coil, allowing functional testing of the controlled circuit. For coil testing, use a multimeter to measure coil resistance (typically 500–2000Ω for AC coils at rated voltage) and compare with datasheet values.

Q: Can the CA2KN22M7 relay be mounted on a DIN rail socket for easy replacement?

A: This Schneider Electric relay typically requires direct panel or DIN rail wiring. For applications requiring frequent relay replacement, consider the plug-in relay variant of this series with a matching socket base.
