Siemens CED63B070 - 70 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens CED63B070 is a 70 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection for panelboards and loadcenters. Built for environments where vibration or movement might impact connections, its secure bolt-on mounting creates a rigid bus connection that stays reliably connected over time.

• Secure bolt-on mounting — delivers a rigid, vibration-resistant connection to the bus, minimizing connection looseness and maintaining consistent protection.
• Thermal-magnetic trip unit — combines precise thermal overload protection with magnetic short-circuit protection for fast, repeatable response to faults.
• 3-pole, 70 A, 600 V — ideal for three-phase distribution in commercial and light industrial systems, providing robust protection for feeders and branch circuits.
• OEM-compatible — engineered to integrate smoothly with matching Siemens OEM loadcenters and panelboards for straightforward installation and uniform protection across the installation.
• Versatile applications — suitable for residential, commercial, and light industrial use, including new builds, panelboard upgrades, and replacement in existing installations.
