Siemens | D230 | Circuit Breaker | 30A | 2-Pole | 240V

Introducing the Siemens D230 Circuit Breaker — a precise 30A, 2-pole, 240V protective device built for reliability in maintenance, retrofit, and replacement projects. When exact compatibility matters, the D230 is designed to align with Siemens panels and the broader electrical infrastructure that relies on safe, simultaneous disconnect of both hot legs.

Key specifications

• Amperage: 30A
• Poles: 2-Pole
• Voltage: 240V
• Part number: D230

Why choose a 2-pole 240V breaker? It provides synchronized disconnection for circuits that use both hot legs, improving safety for large appliances and HVAC equipment. The D230's one-part number reference helps ensure you’re selecting the exact device your panel requires, reducing guesswork during replacements.

Ideal use cases

• Dedicated 240V circuits for large appliances (water heaters, dryers, air conditioners) or high-draw workshop tools
• Retrofit projects where the existing breaker is identified by part number D230
• Replacement in panels that demand Siemens-branded breakers for proper fit and trip characteristics

Before ordering, confirm fit and ratings for your panel. The part number is the best reference for compatibility, ensuring you don’t swap in a breaker that won’t seat or trip correctly in your panel.

Installation and best practices

• Power down the main and verify there’s no load on the circuit before replacing the breaker.
• Verify that your panel accepts Siemens 2-pole 240V breakers with the D230 designation.
• Seat the breaker firmly in the bus and snap it into place, then re-energize and test the circuit with proper testing equipment.

Why Siemens stands out

• Brand-trusted protection with predictable trip performance for 240V circuits.
• Clear part-number guidance to simplify compatibility checks during maintenance or upgrades.

For professionals and DIYers alike, the Siemens D230 30A 2-Pole 240V circuit breaker offers dependable protection, straightforward installation, and confident compatibility with Siemens panels. Keep critical circuits safeguarded with a component built to perform when it matters most.
