⚡ Key Features

4 A AC-3 rated — suits up to a 4 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 where applicable — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised CS940285OOO 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 CS940285OOO rated 4 A for AC-3 motor duty or AC-1 resistive duty?

A: The 4 A rating of this CS940285OOO 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 CS940285OOO selection table.

Q: The CS940285OOO has a coil voltage of 48V DC — what control supply is needed?

A: This CS940285OOO 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: Can the CS940285OOO 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 CS940285OOO 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 CS940285OOO contactors be wired for star-delta starting?

A: Yes. Star-delta starters use three contactors: main (KM1), star (KM2), and delta (KM3). The CS940285OOO 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 CS940285OOO?

A: CS940285OOO 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.
