Schneider Electric GC2530M5 TeSys GC 25 A 3P Contactor

GC2530M5 contactor: three-pole 25 A modular contactor on a 230 V coil

The GC2530M5 is a TeSys GC modular contactor with three normally open power poles, rated 25 A in AC-7a and 8.5 A in AC-7b, and a 220 to 240 V AC 50 Hz coil. It is the choice when a three-phase load, such as a bank of heaters or a lighting feeder, has to be switched from a 230 V control signal. Seven Star LLC supplies the GC2530M5 in Oman and the GCC as an independent supplier based in Muscat.

The 30 in the reference matches the three-pole 3 NO arrangement shown in the datasheet title, and M5 is the 220 to 240 V 50 Hz coil. The module is 36 mm wide, two 18 mm modules, 85 mm high and 62.5 mm deep, and the datasheet lists a net weight of 0.23 kg.

Technical specifications of the GC2530M5

GC2530M5 selection steps

• Count the poles: three 25 A poles, no auxiliary contact is built in.
• Check the voltage across the poles against the 250 V AC maximum in the datasheet.
• Use 8.5 A for motor loads, 25 A only for AC-7a resistive-type duty.
• Control voltage: 220 to 240 V AC at 50 Hz.
• Mounting space: 36 mm of rail width.
• Compare with two-pole units such as the GC2520B5 if only one phase is switched.

GC modular contactor family compared with the GC2530M5

The five GC references below come from the same TeSys GC datasheet series and differ in current rating, pole count and coil. The highlighted row is the one on this page.

Three-phase duty for the GC2530M5

Three poles make the GC2530M5 suitable for a three-phase balanced load, but the rated operational voltage is listed as at most 250 V AC, so on a 400 V network the poles are intended for loads connected phase to neutral or line to line within that limit. Check the voltage across the poles against the datasheet before using it on a higher-voltage circuit.

If the load is a motor, the 8.5 A AC-7b figure applies, not 25 A. For larger motors a TeSys D contactor such as the LC1D09M7 is the more fitting product, with proper AC-3 ratings.

Coil and heat figures for the GC2530M5

The coil draws 34 VA 50 Hz (at 20 °C) at inrush and 4.6 VA 50 Hz (at 20 °C) when held in, according to the datasheet. Total heat dissipation is quoted as 1.6 W at 50/60 Hz, and each power pole dissipates 1.6 W at rated current. For a distribution board these numbers decide how many contactors can sit in one row before the enclosure needs ventilation.

The operating limits are 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). At the lower edge, the contactor may not close on a sagging control supply, which is worth considering for sites with long control cables or weak generator supplies.

Wiring and protection of the GC2530M5

The power terminals take up to 6 mm² flexible conductor and are tightened to 0.8 N.m, as is the control terminal. Associated protection is a 25 A gL fuse for operation up to 440 V. The recommended mounting position is within 30 degrees of vertical so that the moving armature keeps its designed clearance.

Plan an interval for inspection of the poles on circuits that switch often. The datasheet states an electrical durability of 100000 cycles in AC-7a and AC-7b, which at one operation per hour would be several years, but at a few hundred per day is consumed quickly.

GC2530M5 in typical Gulf installations

Commercial buildings in Muscat and across the GCC use three-pole modular contactors for lighting groups, electric heating, air-curtain and small water-heating loads, usually controlled from a timer, BMS or photocell at 230 V.

In industrial sites the same module is common in small control boards, switching resistance heaters of tracing circuits and anti-condensation heaters in panels, where space on the rail is limited.
