Siemens ED63A100 - 100 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Siemens ED63A100 is a 3-pole, 100 A molded case circuit breaker designed to deliver reliable branch circuit overcurrent and short-circuit protection for panelboards and load centers. With a 600 V rating, this unit is ready to guard medium-duty electrical distributions in a variety of settings, from home panels to modest commercial installations and light industrial equipment.

Key advantages that stand out

• Secure bolt-on mounting: A rigid bus connection that resists vibration, keeping your protection device firmly in place in demanding environments.
• Thermal-magnetic trip unit: Combines thermal protection for sustained overloads with magnetic trip for immediate response to short circuits, delivering stable, repeatable protection performance.
• 3-pole design: Provides coordinated protection for all three phases, ensuring balanced interrupting capability across a three-phase system.
• 100 A, 600 V rating: Suitable for distributing substantial loads while maintaining a clear path to rapid disconnection when faults occur.
• OEM panel compatibility: Engineered to fit matching Siemens OEM load centers and panelboards, simplifying upgrades, replacements, and serviceability.
• Versatile applications: Ideal for residential, commercial, and light industrial environments that require dependable branch protection.

In practice, the ED63A100 solves a common but critical problem: protecting conductors and connected equipment from damage due to overcurrent and short circuits. The thermal-magnetic mechanism ensures you won’t experience nuisance trips under normal load growth, while still guaranteeing rapid disconnection during fault events. This combination translates to safer electrical systems, reduced maintenance costs, and longer equipment life.

Practical use cases

• Protect three-phase motors and equipment in light industrial or commercial spaces, such as conveyors, pumps, and HVAC controllers.
• Serve as main or branch protection within commercial panelboards where reliable, compact protection is needed.
• Upgrade residential panels that require robust three-pole protection for multi-line feeders or large loads.

Specifications at a glance align with common distribution needs: 3 poles, 100 A, 600 V, bolt-on mounting, and OEM-friendly compatibility. The ED63A100 is a practical choice when you require a dependable, easy-to-service protection device that doesn’t compromise on performance or fit within existing panel architectures.

Upgrade or install with confidence: the Siemens ED63A100 is purpose-built to deliver consistent, long-term protection for your electrical system’s branch circuits, helping you maintain safe operation across a range of installations.
