Westinghouse CNDC312T36W Circuit Breaker — 1200A, 3-Pole, 600V

The Westinghouse CNDC312T36W is a rugged, high‑current circuit breaker designed for demanding electrical environments. With a 1200A rating across 3 poles and a 600V operating voltage, this unit provides dependable protection for large feeders in industrial panels, commercial power distribution, and retrofit projects where exact specifications matter.

Key specifications

• Amperage: 1200A
• Poles: 3‑Pole
• Voltage: 600V
• Part reference: CNDC312T36W

What makes this breaker stand out

Compared to standard residential or lighter‑duty breakers, the CNDC312T36W is built to handle the demands of three‑phase power distribution. It’s specifically suited for maintenance, retrofit, and replacement scenarios where matching specs are non‑negotiable. The part number CNDC312T36W serves as the most reliable reference for compatibility, helping you avoid mismatches in panel boards and feeders.

Ideal use cases

• Upgrading or replacing tripping devices in industrial control panels and large commercial distribution boards.
• Retrofitting legacy systems that require a 3‑pole, 600V, high‑current protection solution.
• Maintenance projects in data centers, manufacturing floors, and other facilities with heavy electrical loads.

Why “fit” matters—and how to verify it

Before ordering, confirm that the CNDC312T36W matches your panel’s specifications and the downstream wiring arrangement. The part number is your best guide to compatibility, ensuring correct trip characteristics and mechanical fit for your enclosure. If you’re replacing an existing unit, compare the mounting pattern and terminal configurations to avoid installation delays.

Practical tips for installation and use

• Shut down and lock out power before any replacement work. Verify absence of voltage at all conductors and follow site safety procedures.
• Double‑check the panel labeling to ensure three‑phase coverage and correct bus alignment.
• Store replacement breakers in compatible environments to prevent corrosion or damaged terminals before installation.
• Keep spare CNDC312T36W units on hand for planned maintenance to minimize downtime in critical systems.

Designed for professionals who demand reliability in high‑current, three‑phase applications, the Westinghouse CNDC312T36W delivers controlled, predictable interruption when faults occur, helping protect equipment and sustain power availability across your facility.
