Schneider TeSys LADN22 Front Auxiliary Contact Block, 2NO + 2NC
Submit your RFQ. Our team will send a quotation confirming price and availability.
Schneider Electric LADN22 is a front-mounted TeSys Deca auxiliary contact block with 2NO + 2NC instantaneous contacts for compatible contactors and control relays. Screw-clamp terminals support control and signalling wiring. Its 10A thermal rating is separate from the voltage-dependent AC-15 and DC-13 switching ratings. The contactor or control relay is selected separately.
