Product details

The LA1KN113M is a TeSys K auxiliary contact block — 1 NO + 1 NC instantaneous contacts, front-mounted onto a contactor or starter base (EN 50012 profile). Spring-cage terminals accept 0.75…1.5 mm² flexible or rigid cable. It is rated 10 A conventional free-air thermal current (Ith) at 50 °C, with a rated insulation voltage (Ui) of 690 V per IEC 60947-5-1 and 600 V per UL/CSA. Lifecycle: this order code is marked obsolete. There is no official successor listed on the record, so any replacement must be verified against the existing panel layout — contact rail spacing, terminal style, and the front-mounting footprint.

Integration and mounting constraints

Mounts on the front of a TeSys K contactor or reversing starter. Spring terminals — no screw torque to check, but the strip length needs to be clean 8 mm to avoid whiskers under the cage. The 690 V AC insulation (25…400 Hz) covers 480 V and 600 V line-to-line systems with margin.

Frequently asked questions

What is the closest pin-compatible replacement?

No official successor order code is published for LA1KN113M. A parametric cross-reference against TeSys D or Deca front-mount auxiliary blocks should be done on terminal pitch, contact configuration (1NO+1NC), and mounting profile (EN 50012). Verify before ordering — the record does not name a direct substitute.

What are the key ratings for LA1KN113M?

1NO+1NC instantaneous contacts, 10 A Ith at 50 °C, 690 V rated insulation voltage (IEC) / 600 V (UL/CSA), IP20 finger-safe, spring terminals for 0.75…1.5 mm² wire, dimensions 35 mm deep × 38 mm wide × 30 mm tall.

What compliance documentation exists for this part?

The part carries IEC 60947-5-1, UL 60947-5-1, and CSA C22.2 No. 60947-5-1 ratings for insulation voltage. The protective treatment is TC conforming to IEC 60068. No RoHS or REACH statement is in the record.
