⚡ Key Features

55 A AC-3 rated — suits up to a 30 kW squirrel-cage induction motor at 415V for direct-on-line (DOL) starting and running.
48V DC coil — connects directly to pushbutton station, PLC digital output, or timer relay; suitable for standard 50Hz Indian industrial control circuits.
4 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.
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.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: Is the LC1DT55ED rated 55 A for AC-3 motor duty or AC-1 resistive duty?

A: The 55 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 LC1DT55ED has a coil voltage of 48V DC — what control supply is needed?

A: This Schneider Electric device requires a 48V 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 is the electrical and mechanical life of the LC1DT55ED?

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.

Q: Can the LC1DT55ED be used for reversing duty (forward/reverse motor control)?

A: Contactors used for reversing must be wired with two contactors interlocked so only one can energise at a time. The Schneider Electric series provides mechanical interlock kits that physically prevent both contactors from closing simultaneously — mandatory for reversing and brake applications to prevent phase-to-phase short circuits.

Q: Can multiple LC1DT55ED 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.
