Siemens ED61B045L - 45 A, 600 V, 1-Pole Circuit Breaker | AmpState

Meet the Siemens ED61B045L — a 1-pole, 45A molded-case circuit breaker built to safeguard your panelboards and load centers from overcurrent and short-circuit events. With a robust 600V rating, it delivers reliable protection for single‑phase branch circuits in residential, commercial, and light industrial environments.

• Compact molded-case design: Streamlined footprint that maximizes panel space without compromising protection, making it ideal for crowded service panels or retrofit installations.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by automatically responding to sustained overloads (thermal) and instantaneous short-circuits (magnetic), reducing nuisance trips and protecting wiring and devices.
• 1-pole configuration: Provides targeted branch circuit protection for single‑phase circuits such as lighting, receptacles, and small equipment in panelboards and load centers.
• 600V electrical rating: Suitable for a broad range of commercial and light industrial applications, ensuring compatibility with higher‑voltage distribution where required.
• OEM-compatible design: Engineered to work seamlessly with matching Siemens panelboards and OEM load centers, simplifying replacement and ensuring reliable performance with existing infrastructure.

The ED61B045L is the practical choice when you need dependable, code-compliant protection for critical circuits. It safeguards wiring insulation from overheating, minimizes equipment damage from faults, and supports safer electrical systems with predictable tripping behavior — a cornerstone for any well‑designed electrical panel.

Who should consider this breaker? electricians, facility managers, and maintenance teams looking to refresh or expand single‑pole protection in residential, commercial, or light industrial settings. If you’re upgrading aging equipment, replacing a failed breaker, or configuring new circuits in a Siemens‑based panel, the ED61B045L offers a straightforward, reliable solution.
