⚡ Key Features

80 A AC-3 rated — suits up to a 37 kW squirrel-cage induction motor at 415V for direct-on-line (DOL) starting and running.
24V AC 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.
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 CS97077GOOO 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 CS97077GOOO rated 80 A for AC-3 motor duty or AC-1 resistive duty?

A: The 80 A rating of this CS97077GOOO 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 CS97077GOOO selection table.

Q: The CS97077GOOO has a coil voltage of 24V AC — what control supply is needed?

A: This CS97077GOOO device requires a 24V AC control supply connected to the coil terminals (A1 and A2). For AC coils, ensure the control circuit voltage is stable — voltage drops below 85% of rated coil voltage can cause chatter and coil overheating. Always fit a surge suppressor across the coil when switching with a PLC or solid-state relay.

Q: Can multiple CS97077GOOO contactors be wired for star-delta starting?

A: Yes. Star-delta starters use three contactors: main (KM1), star (KM2), and delta (KM3). The CS97077GOOO 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 CS97077GOOO?

A: CS97077GOOO 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 CS97077GOOO 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 CS97077GOOO 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.
