Product details

The G12T3F32 is a GoPact MCCB 125, a 3-pole thermal-magnetic moulded-case circuit breaker with a TM-D trip unit rated 32 A at 40 °C.

Deployment context

Fixed-mount, backplate-mounted, with front-facing screw terminals for both line and load connections.

Suitable for isolation per that standard — meaning when open, it provides a visible break that meets the safety disconnection requirement. Overvoltage category III (distribution level).

Durability and thermal budget

Rated for 8000 electrical cycles at rated current and 415 V, and 30,000 mechanical cycles. Each pole dissipates 18.7 W at rated current — three poles total 56.1 W of heat inside the enclosure, so factor that into your panel thermal calculation. Ambient operating range -20 to 55 °C, storage -35 to 85 °C.

Frequently asked questions

Where can I buy G12T3F32 and how do I get a price?

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 price and lead time.

What is G12T3F32's listed colour?

Grey (RAL 7035), which is the standard industrial grey for Schneider Electric's GoPact range.

What compliance documentation does this brand provide for G12T3F32?

The part is designed to EN/IEC 60947-1, EN/IEC 60947-2, and EN/IEC 60947-2 Annex H. It carries suitability for isolation per that standard. Specific RoHS, REACH, and UL documentation should be confirmed at time of order; the evidence does not list those separately.
