3-Pole Molded Case Circuit Breaker

The ABB Formula A2 molded case circuit breakers are designed for reliable branch and feeder circuit protection in commercial and industrial power distribution systems.

Available in two amperage options, these 3-pole breakers feature thermal-magnetic trip units, fixed front-terminal construction, and compact A2 frame sizing for efficient installation.

Available Variations

• ABB A2A200TT – 200A, thermal-magnetic trip unit
• ABB A2A225TT – 225A, thermal-magnetic trip unit

Both models share identical construction and ratings, with the primary difference being the continuous current rating (200A vs 225A).

Key Features

• ABB Formula A2 molded case circuit breakers
• 3-pole configuration
• Available in 200A and 225A ratings
• Thermal-magnetic trip units for overload and short-circuit protection
• A2 frame (250A frame size)
• Fixed breaker design with front terminals
• Suitable for 240V AC and 250V DC applications
• 10 kAIC interrupting rating at 240V
• Compact footprint for panelboard and switchboard installations

Typical Applications

Ideal for panelboards, switchboards, motor control centers, and industrial distribution systems requiring reliable overcurrent protection in a compact form factor.

Construction Details

Built on ABB’s proven Formula A platform, these breakers offer durable molded case construction with consistent performance across a wide range of applications.

Front-access terminals simplify installation and maintenance in confined electrical enclosures.

Thermal-magnetic protection ensures dependable response to overload and short-circuit conditions.

Important Notes

Always confirm system voltage, interrupting rating, and mounting compatibility prior to installation.

Installation should be completed by qualified personnel following NEC and local electrical codes.

Consult ABB technical documentation for detailed specifications and accessory options.
