Siemens 3RV2011-1CA10 - 3-Pole Circuit Breaker | AmpState

Meet the Siemens 3RV2011-1CA10, a 3-pole molded case circuit breaker crafted for dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Designed to support three-phase systems, it delivers reliable protection where it matters most—across residential, commercial, and light industrial applications.

• Efficient panel space — The compact molded-case design maximizes panel real estate, allowing cleaner layouts in crowded panelboards and loadcenters.
• Thermal-magnetic trip unit — Combines thermal overload protection with magnetic short-circuit protection for stable, repeatable performance across varied loads and fault conditions.
• 3-pole protection for 3-phase systems — Ensures all three hot conductors trip together, minimizing fault risk and simplifying downstream wiring protection.
• OEM-compatible — Built to be perfectly compatible with matching Siemens loadcenters and panelboards, promoting streamlined installation, easier maintenance, and coordinated protection.
• Versatile by design — Ideal for residential, commercial, and light industrial environments where reliable branch circuit protection is essential.

Use cases and practical benefits

In a three‑phase commercial panel, the 3RV2011-1CA10 provides robust protection for lighting, HVAC, pumps, and small motors wired across three hot legs. It’s an excellent replacement option when upgrading from smaller pole devices or when expanding a panel to handle additional three‑phase circuits. Because it’s designed to integrate with Siemens OEM systems, you’ll experience predictable trip characteristics and straightforward diagnostics during service or inspection.

Why this breaker stands out

Rather than a generic alternative, the 3RV2011-1CA10 is purpose-built for Siemens panelboards and loadcenters, ensuring tight electrical coordination and reliable performance in real-world conditions. Its molded case construction provides durability in environments with vibration or temperature variation, while the thermal-magnetic trip mechanism delivers precise protection without unnecessary interruptions. For professionals stocking parts or maintaining mixed-use facilities, sourcing this exact unit from AmpState simplifies ordering and guarantees compatibility with existing Siemens installations.

Tips for installation and care

Before installation, confirm that the panelboard supports 3-pole Siemens breakers and that the device rating aligns with the circuit requirements. Use this breaker in Siemens‑compatible loadcenters to maintain coordinated protection across the panel. Keep a spare 3RV2011-1CA10 on hand for quick maintenance and downtime reduction in critical systems.
