Schneider Electric G20B3A200 GoPact MCCB GoPact 200B 3P 200A 25kA TMD | Molded Case Circuit Breaker

The Schneider Electric G20B3A200 is a GoPact GoPact 200B molded case circuit breaker rated 200A, 3-pole, with 25 kA breaking capacity and a adjustable thermal-magnetic (TMD) 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

• Adjustable thermal-magnetic (tmd) protection with adjustable overload setting
• Breaking capacity 25 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 G20B3A200?

The G20B3A200 (GoPact 200B) has a breaking capacity of 25 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.
