Schneider Electric GC2520M6 TeSys GC 25 A 2P 60 Hz Contactor
Description
GC2520M6 contactor: the 60 Hz, 220 to 240 V coil version of the 25 A GC contactor
The GC2520M6 is the TeSys GC 25 A two-pole modular contactor with a 220 to 240 V AC coil specified for 60 Hz control circuits. Its power section is the same as the other GC25 two-pole units: two normally open poles, AC-7a rating of 25 A, 250 V maximum operational voltage. What separates it is the coil, and the coil frequency is the reason a buyer asks for this reference instead of the 50 Hz one. Seven Star LLC supplies the GC2520M6 in Oman and the GCC as an independent supplier based in Muscat.
In the reference, GC25 gives the frame, 20 the two-pole arrangement, and M6 the mains-voltage 60 Hz coil that the datasheet title spells out as 220 to 240 V AC 60 Hz. Equipment built for North American or Asian markets and shipped to Gulf sites is the usual origin of 60 Hz control.

Matching the GC2520M6 to a 60 Hz installation
Most Gulf networks run at 50 Hz, so a 60 Hz contactor is a deliberate choice. It fits imported machines, marine and offshore packages and skids from 60 Hz countries, where the control supply is generated or transformed at 60 Hz. If the machine uses a 230 V control circuit at 50 Hz, a 50 Hz coil version is the correct neighbour instead.
The power side is unaffected by the coil frequency. Two poles switch a single-phase load up to 25 A AC-7a at up to 250 V AC, so lighting banks, heater elements and resistive loads are the natural fit.
What the 60 Hz coil means for the GC2520M6
The datasheet lists the control circuit type as AC at 60 Hz with a coil range of 220 to 240 V. Inrush is 15 VA 50 Hz (at 20 °C) and hold-in is 3.8 VA 50 Hz (at 20 °C), with the operating limits written as Drop-out: 0.2 to 0.75 Uc at 50 Hz (at <50 °C); Operational: 0.85 to 1.1 Uc at 50 Hz (at <50 °C).
Be careful when swapping coils between 50 and 60 Hz machines. A coil made for one frequency can overheat or chatter at the other, so a replacement should always carry the frequency that the control supply actually has.

GC2520M6 ordering checklist
- Confirm the control frequency is 60 Hz and the voltage lies in the 220 to 240 V range.
- Check the load type: 25 A applies to AC-7a, while 8.5 A applies to AC-7b motor duty.
- Check the number of poles needed; this is the two-pole version with 2 NO.
- Mounting is a clip-on DIN rail module, 17.5 mm wide.
- Look at the sale unit in the datasheet: it quotes a set quantity of 12 for this reference.
- Compare the part with the existing nameplate if you replace a unit, since the coil code is on the front.
Where a 60 Hz GC2520M6 turns up in Oman and the GCC
Typical sites are imported packaged plant: desalination and water-treatment skids, camp and accommodation equipment, workshop machines and marine auxiliaries built to 60 Hz standards. The contactor often drives a heater, a lighting contactor circuit or a small auxiliary load inside such a package.
For spares, the 60 Hz coil is the detail that people forget. Keeping the GC2520M6 as a labelled spare avoids a machine standing idle because only the 50 Hz variant was in stock.
Installing the GC2520M6
Clip the module on the rail, wire the 60 Hz coil to A1 and A2 and the load across the two power poles. Screw clamps on both circuits are tightened to 0.8 N.m according to the datasheet.
After energising the circuit, check that the coil does not hum. Hum or heat points to a wrong frequency or a supply with high harmonic content, and it is much cheaper to find that at commissioning than after the first summer.

About brand
Schneider Electric is the French group for energy management and industrial automation: low and medium voltage switchgear and circuit breakers, motor control, drives, PLCs, power monitoring, UPS systems and building management. Its history goes back to 1836, when the brothers Adolphe and Eugène Schneider took over the iron and steel works at Le Creusot in Burgundy. Over the 20th century the company left steel and heavy engineering and became an electrical group through acquisitions such as Merlin Gerin, Télémécanique, Square D and Modicon. Its head office is in Rueil-Malmaison near Paris, and its shares are listed on Euronext Paris.

Choosing Schneider Electric breakers and motor control
Circuit breakers are chosen by current and breaking capacity. Acti9 miniature circuit breakers (iC60, C120) protect final circuits up to 125 A. ComPacT NSX molded case breakers cover about 16 to 630 A, and the letter after the frame size sets the breaking capacity: B, F, N, H, S, L from lowest to highest. MasterPacT air circuit breakers are used as main incomers on large switchboards. For motors, a TeSys contactor with an LRD overload relay or a GV2 motor circuit breaker suits direct starting, an Altistart soft starter reduces starting current, and an Altivar drive controls speed. The breaking capacity must always be at least the prospective short-circuit current at the point of installation.
Where Schneider Electric products are used
In Oman and the GCC, Schneider Electric equipment is found in main and sub-main switchboards of commercial and residential buildings, motor control centres in water, oil and gas and industrial plants, substations protected by Sepam and Easergy relays, data centres powered by Galaxy and APC UPS systems, and buildings controlled by EcoStruxure Building Operation.
APC by Schneider Electric: UPS and critical power
Since 2007, APC has been part of Schneider Electric and is now its product brand for uninterruptible power supplies, replacement batteries, battery packs, network management cards and rack power distribution. Our APC catalogue covers Smart-UPS line-interactive and on-line models, Easy UPS On-Line, the modular Symmetra LX, RM and PX ranges, Silcon three-phase systems and their spare part kits, and the RBC cartridges that keep them running. Schneider Electric breakers, drives and PLCs can be quoted together with APC UPS systems in one request.
