⚡ Key Features

18 A AC-3 rated — suits up to a 11 kW squirrel-cage induction motor at 415V for direct-on-line (DOL) starting and running.
24V DC coil — connects directly to pushbutton station, PLC digital output, or timer relay; suitable for standard 50Hz Indian industrial control circuits.
3 Poles main contacts with silver-alloy (AgSnO₂) tips — rated for AC-3 duty (DOL motor starting/stopping); low contact resistance reduces heat at rated current.
Main contacts rated up to 440V AC — compatible with 415V AC three-phase Indian supply and 480V AC North American systems.
TeSys D series — world-standard contactor footprint; clip-on LA1D/LA4D auxiliary contact blocks and accessories attach without tools; compatible with TeSys LRD overload relays for direct-mount DOL starters.
Manufactured to IEC 60947-4-1 / IS 13947-4-1 — 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.

❓ Frequently Asked Questions

Q: Is the LC1D18BL rated 18 A for AC-3 motor duty or AC-1 resistive duty?

A: The 18 A rating of this Schneider Electric contactor applies to AC-3 duty (squirrel cage motor starting and running). For AC-1 (resistive/non-inductive) loads, the current can be up to ~1.3× the AC-3 rating. AC-4 (plugging/reversing) requires significant de-rating — consult the Schneider Electric selection table.

Q: The LC1D18BL has a coil voltage of 24V DC — what control supply is needed?

A: This Schneider Electric device requires a 24V DC control supply connected to the coil terminals (A1 and A2). For DC coils, observe polarity where marked. DC coils produce no inrush and are preferred for PLC output cards. Always fit a surge suppressor across the coil when switching with a PLC or solid-state relay.

Q: What circuit can the 3 NO (Normally Open) contacts of the LC1D18BL switch at 440V AC?

A: The 3 NO (Normally Open) contacts on the LC1D18BL are rated for switching at up to 440V 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: Can multiple LC1D18BL contactors be wired for star-delta starting?

A: Yes. Star-delta starters use three contactors: main (KM1), star (KM2), and delta (KM3). The Schneider Electric contactor series supports mechanical and electrical interlocking accessories that prevent simultaneous energisation of star and delta contactors — critical for safety. Ensure all three contactors are rated correctly for the motor FLC and star-delta transition current.

Q: What is the electrical and mechanical life of the LC1D18BL?

A: Schneider Electric contactors are rated for millions of operations: typically 10–30 million mechanical operations and 1–3 million electrical operations at rated current and voltage (AC-3 duty). High-frequency switching applications (>10 operations/hour) require checking the specific thermal capacity of the contactor for continuous duty without overheating.
