Schneider Electric G12T3F25 GoPact MCCB GoPact 125T 3P 25A 10kA TMD | Molded Case Circuit Breaker

The Schneider Electric G12T3F25 is a GoPact GoPact 125T molded case circuit breaker rated 25A, 3-pole, with 10 kA breaking capacity and a fixed thermal-magnetic trip unit. It provides reliable overload and short-circuit protection for sub-main feeders, distribution boards, pump and HVAC panels and building risers in commercial, residential and industrial low-voltage installations.

Key features

• Fixed thermal-magnetic protection
• Breaking capacity 10 kA for installations with high fault levels
• 3-pole version for three-phase networks
• Positive contact indication and suitable for isolation
• Wide range of accessories: auxiliary contacts, shunt and undervoltage releases, rotary handles
• Compact frame that fits standard switchboards and panel enclosures

Technical specifications

Typical applications

• Main and sub-main distribution boards (MDB / SMDB)
• Transformer, generator and ATS panels
• Pump, HVAC, chiller and elevator feeders
• Factories, malls, hospitals, towers and data centres
• Replacement of old MCCBs in existing switchboards

Selection guide

Choose the rated current according to the cable and the load, the breaking capacity (Icu) higher than the prospective short-circuit current at the installation point, and the number of poles according to the earthing system. Use 4-pole breakers where the neutral must be switched or protected, and check discrimination with downstream MCBs.

Frequently asked questions

What is the breaking capacity of the G12T3F25?

The G12T3F25 (GoPact 125T) has a breaking capacity of 10 kA at 380/415 V AC.

What is the difference between MCCB and MCB?

MCCBs cover higher currents (typically 16 A to 1600 A), higher breaking capacities and often adjustable protection, while MCBs are used for final circuits up to 125 A.

Which accessories fit this breaker?

GoPact breakers accept auxiliary/alarm contacts, shunt (MX) and undervoltage (MN) releases, rotary handles and terminal shields from the same range.
