Siemens Q3100H - 100 A, 240 V, 3-Pole Plug-In Circuit Breaker | AmpState

Siemens Q3100H 100 A, 240 V, 3-pole plug-in molded case circuit breaker is engineered to deliver dependable branch circuit overcurrent and short-circuit protection right where you need it—within panelboards and loadcenters. Built for fast, reliable service, this unit combines precise protection with a streamlined installation that keeps downtime to a minimum.

• Fast plug-in connection enables quick installation and easy replacement, reducing panel downtime during upgrades or servicing in residential, commercial, and light industrial settings.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining thermal overload sensing with magnetic short-circuit interrupting capability. This means predictable tripping behavior even under varying load conditions, helping prevent damage to wiring and connected equipment.
• OEM-compatible design is matched to Siemens panelboards and loadcenters for a secure fit, proven performance, and reliable long-term operation.
• Three-pole configuration ensures simultaneous disconnection across all phases, reducing the risk of residual current faults and protecting equipment in 3-phase systems.
• Versatile application suitable for residential, commercial, and light industrial electrical layouts, including service panels, subpanels, and distribution centers where robust protection is essential.

Why this matters

When protecting branch circuits, precise coordination between overcurrent protection and short-circuit interruption is crucial. The Q3100H’s 100 A rating handles substantial load centers while its plug-in form keeps installation straightforward and service-friendly. The thermal-magnetic trip curve helps minimize nuisance trips in everyday profiles and delivers consistent protection as electrical demand evolves in your building.

Key specifications at a glance

Who should consider the Siemens Q3100H
