⚡ Magnum DS Breakers Fixed and Drawout Configurations

The Magnum DS line is known for its modular construction and working with a wide range of applications. You’ll like how easily these breakers adapt to different electrical systems. They support both fixed and drawout breaker configurations, meaning you can design for maintenance flexibility or space-saving layouts.

Need 3-pole or 4-pole options? Or want to access the trip unit without opening the panel door? Eaton’s Magnum through-the-door design gives you that convenience. The breakers also support manual and motorized breaker spring charging, making them great for local and remote operation. Finally, the Magnum DS breaker wiring diagram is easy to follow, and helps you streamline installation and reduce commissioning time.

📊 Frame Sizes and Current Ratings for Magnum DS Renewal Parts

Your system needs may vary, so Eaton’s Low Voltage Magnum DS covers four frame sizes, letting you specify the right current capacity and physical footprint for the job:

Frame Size	Current Range	Width	Recommended Use	Example Part Number
Narrow Frame	800–2000A	13.2 in (336 mm)	Space-constrained enclosures	MDS8203
Standard Frame	800–3200A	17.0 in (432 mm)	Most vertically stacked systems	MDS3200
Double Narrow Frame	4000A	26.3 in (667 mm)	Higher current in tighter spaces	MDS4000
Double Standard Frame	3200–5000A	35.8 in (909 mm)	Main/tie breaker setups	MDS5000DS

🧮 Magnum DS Breakers for High Fault Protection, Safety

With a Magnum DS Breaker Replacement, you’re getting breakers rated up to 200 kA interrupting power and 130 kA at 635V. This means the maximum current the breaker can withstand for a short period without damage or tripping, at 635 volts. These high fault ratings let you build systems with improved selectivity and lower risk of cascading failures.

If you’re comparing options, the Magnum DS Low Voltage circuit breaker ratings meet or beat competitors, especially when you factor in their current-limiting performance and optional arc flash reduction technology.

🛠️ Digitrip RMS Trip Unit for Smart Electrical Protection

Eaton’s Magnum DS features a Digitrip RMS trip unit, providing LSI, LSIG, and LSIA protection schemes. Basically, this means these trip units aren’t just configurable — they’re smart. They offer real-time diagnostics, metering, and event logging.

If you’re weighing Eaton Magnum DS trip unit options, look at models like the 520MC or 1150 — both offer Arcflash Reduction Maintenance System (ARMS) features. This lowers incident energy during maintenance and helps you meet safety requirements without derating your breaker.

Magnum DS is also reverse feed capable. This is useful in load-sharing or backup source scenarios. The trip unit can be factory-installed or field-upgraded, helping to future-proof the breaker within your system.

Accessories and Configuration Options

Here’s a list of Eaton Magnum DS accessories to complete your setup. Eaton offers plug-in and internal accessories to fit your control scheme:

You can order your breaker with everything pre-installed, or add accessories later — most are field-installable. Drawout options include basic, standard, and universal cassettes. If you’re planning an automatic transfer switch (ATS) application, request the dual arc hood option. This setup is also ideal for Magnum DS breakers with frame sizes of 3200A and above.

Understanding Magnum DS Catalog Number Structure

If you’re configuring a new breaker, knowing how to read the catalog number is helpful. The Eaton Magnum DS catalog number is a 25-character string that identifies:

Breaker family (MD = Magnum DS)
Frame type and size (e.g., 1200A Narrow)
Interruption rating (42 kA to 200 kA)
Trip unit type and voltage
Accessories (e.g., auxiliary switch, shunt trip, motor operator)
Shipping and wiring options
