⚡ Key Features

Genuine SS946511OOO OEM accessory — manufactured to the same specification and tested to the same standards as the parent device; ensures mechanical and electrical compatibility that third-party alternatives cannot guarantee.
Undervoltage release (MN/MNF) — holds the circuit breaker closed only while control voltage is present above ~70% of nominal; automatically trips on voltage loss, preventing re-energisation after a power failure without operator action.
Release rated 110V DC — must be permanently energised while the breaker is in the ON position; connect to a reliable supply (UPS or separate feeder) to avoid nuisance tripping.
Direct clip-on or screw-mount to parent device — fits without panel modification or additional wiring between the accessory and main device; field-retrofittable.
Manufactured to IEC 60947 (tested as part of the parent device certification) — 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 SS946511OOO 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: The SS946511OOO has a coil voltage of 110V DC — what control supply is needed?

A: This SS946511OOO device requires a 110V 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: How do I know the SS946511OOO replacement coil matches my contactor?

A: Match three things: (1) the contactor series and frame size stated for the SS946511OOO, (2) the coil voltage — the replacement must equal the control circuit voltage exactly, and (3) AC or DC supply type. Fitting a coil of the wrong voltage causes failure to pull in (too low) or coil burnout (too high). The original coil’s voltage is printed on its face — verify before ordering.

Q: What causes a contactor coil to fail and need replacement like the SS946511OOO?

A: The most common causes are: sustained undervoltage (coil hums and overheats while failing to seal the magnetic circuit), overvoltage, voltage spikes from nearby switching inductive loads, dust or rust on the magnet faces preventing full closure (coil draws inrush current continuously), and simple ageing of the insulation. If coils fail repeatedly, fit a surge suppressor and check the control supply voltage stability before fitting the new coil.
