Why this breaker stands out

Beyond basic protection, the shunt trip capability adds a critical layer of safety for systems that require rapid, remote disconnection. This is especially valuable in facilities with safety interlocks, elevator machinery, or equipment bays where a quick, decisive shutdown protects personnel and assets. The 3-pole configuration provides balanced protection across a three-phase system, while the 200 A rating suits mid-sized distribution feeders without compromising reliability.

Ideal use cases

Perfect for:

• Retrofit projects where the exact part number must be preserved for warranty, documentation, or compatibility reasons
• Maintenance planning in panelboards and load centers that demand consistent, approved components
• Safety-focused electrical distribution where remote trip capability enhances protection strategy

How it compares, and what it solves

If you’re upgrading or refurbishing an existing three-phase distribution system, this KA362001021 model simplifies procurement with a fixed 200 A, 3P, 600 V specification and embedded shunt trip. It reduces inventory complexity by sticking to a standardized part number across multiple service cycles, while delivering the precise protective characteristics your system requires.
