Siemens CED63B020 - 20 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the Siemens CED63B020 — a 20A, 600V, 3-pole bolt-on molded case circuit breaker purpose-built for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. engineered for consistent performance, this breaker is a practical upgrade or replacement option for demanding electrical installations.

Key advantages that matter in real-world use

• Secure bolt-on mounting delivers a rigid, vibration-resistant bus connection, reducing micro-movements that can lead to loose contacts or nuisance trips in busy electrical rooms or machinery spaces.
• Thermal-magnetic trip unit provides stable thermal overload protection together with rapid magnetic action for short circuits, delivering repeatable protection without compromising system uptime.
• 3-pole, 20A, 600V rating is ideal for three-phase feeder circuits and protected loads in light commercial and certain industrial environments, helping you manage power distribution with confidence.
• OEM panelboard compatibility is designed to integrate smoothly with matching Siemens loadcenters and panelboards, ensuring fit, clear labeling, and straightforward installation.
• Versatile application suitable for residential, commercial, and light industrial applications where reliable branch circuit protection is essential.

How it protects your system

Inside the Siemens CED63B020, the thermal element tracks current-induced heating, triggering protection as soon as overload conditions persist. If a fault occurs, the magnetic mechanism engages for an instantaneous trip, interrupting current to prevent damage to conductors, devices, and downstream equipment. The bolt-on design ensures a solid, low-resistance connection to the bus, promoting long-term reliability.

Ideal use cases

• New installations in small-to-mid size commercial spaces that require robust three-pole protection.
• Retrofits in existing Siemens panelboards where space efficiency and dependable performance are priorities.
• Three-phase feeders in light industrial environments (HVAC, pumps, conveyors) where vibration and variable loads are common.
