The LP1K06016BD3 is a 3-pole contactor from the TeSys K range, rated for AC-3 and AC-4 utilisation categories up to 440 V. Its 6 A rated operational current covers small motor switching and signalling circuits. The 24 V DC coil includes a built-in bidirectional peak limiting diode suppressor, which simplifies panel wiring by eliminating the need for an external flyback diode across the coil. Flame retardance is V1 per UL 94, also meeting NF F 16-101 and NF F 16-102 Requirement 2 — relevant for rail and transit applications where fire-smoke-toxicity compliance is specified.
Integration into a panel
The 3 NO main poles and 1 NC auxiliary contact are pre-configured; no auxiliary block to add for basic signalling. Coil hold-in power is 3 W at 20 °C, with the same 3 W inrush. The built-in diode suppressor handles back-EMF, so no additional snubber is needed on the DC coil circuit — just confirm polarity before energising.
