Siemens CQD360 - 60 A, 480 V, 3-Pole Circuit Breaker | AmpState

Siemens CQD360 is a 60 Amp, 480-volt, 3-pole molded case circuit breaker engineered to protect branch circuits in panelboards and load centers from overloads and short circuits. Its compact design fits tight panel layouts while delivering dependable protection where three-phase power is essential.

• 60A, 3-Pole, 480V rating enables reliable protection for three-phase circuits in commercial and light industrial environments.
• Thermal-magnetic trip unit delivers stable, repeatable protection performance, responding quickly to short circuits and preventing nuisance trips on normal startup surges.
• Compact molded-case design optimizes panel space, making it easier to fit more circuits in load centers and panelboards without sacrificing protection quality.
• OEM compatibility designed to integrate seamlessly with matching Siemens load centers and panelboards, ensuring proper fit, electrical characteristics, and serviceability.
• Versatile application suitable for residential, commercial, and light industrial installations that require robust 3-phase 480V protection.

Why this breaker matters for your electrical system

The CQD360 protects downstream equipment from damaging overcurrent and short-circuit events, helping to minimize downtime and equipment wear. Its thermally responsive mechanism helps balance protection with low nuisance tripping, while the three-pole design aligns with typical 480V three-phase feeders—common in retail complexes, manufacturing floors, and data-center infrastructure.

Use cases and ideal installations

• New builds and retrofits in panelboards that service three-phase 480V equipment such as motors, conveyors, HVAC systems, and heavy lighting circuits.
• Upgrading existing protection schemes in commercial spaces to ensure compliant, reliable branch-circuit protection.
• Equipment feeders in light industrial environments where compact form and dependable interruption are priorities.
