Product details

IP20 finger-safe protection means it is suitable for enclosed panel installation where personnel access is restricted to qualified electricians.

Within the GoPact MCCB family, this 125 A TM-D unit is the mid-range thermal-magnetic option — higher than the 100 A frame, lower than the 160 A. The TM-D trip unit is the standard thermal-magnetic type for distribution; if you need electronic trip adjustability (LSI or LSIG), you step up to the GoPact EZC or NSX series. The deciding factor for this part is fixed 125 A protection with no adjustment — simple, reliable, and footprint-matched to the existing panel cutout.

Rated operational voltage is 415 V AC 50/60 Hz per EN/IEC 60947-2, with an insulation voltage of 440 V AC. It is suitable for isolation per the same standard — meaning when open, it provides a visible-break isolation gap for safe maintenance. Electrical durability is 5000 cycles at rated current and voltage; mechanical durability is 30,000 cycles. Ambient operating range is -20 to 55 °C; storage range is -35 to 85 °C.

Frequently asked questions

Where can I buy the G12E3F125 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commercial offer.

What is the breaking capacity of the G12E3F125?

The performance level is E, which corresponds to 15 kA at 380/415 V AC. That is the maximum fault current it can safely interrupt at that voltage.

What standards does the G12E3F125 comply with?

It complies with EN/IEC 60947-1, EN/IEC 60947-2, and EN/IEC 60947-2 Annex H. It is also suitable for isolation per EN/IEC 60947-2.
