MDA200 - 200 Amp Circuit Breaker

MDA200 - 200 Amp Circuit Breaker

The MDA200 is a 200 amp, 2-pole MD-A plug-in main residential thermal magnetic circuit breaker rated 120/240VAC with a 10k A.I.C. rating. When you're matching a breaker for existing residential equipment, amperage is only part of the picture. Where all required specifications match, the MDA200 can be considered a form, fit, and functional replacement candidate for compatible existing or legacy residential electrical equipment. Its solid construction is built to last when selected, installed, and maintained correctly.

Key Features and Benefits

• 200 Amp, 2-Pole Configuration: Provides the specified 200A rating in a two-pole design for compatible residential main-breaker applications.
• 120/240VAC Rating: Clearly rated for 120/240VAC applications, making voltage verification straightforward during replacement work.
• Thermal Magnetic Operation: Identified specifically as a thermal magnetic circuit breaker.
• Plug-In Main Breaker: The plug-in configuration is a key form-and-fit characteristic when matching the MDA200 to compatible residential equipment.
• Parallel Lug-Terminal Wire Entry: Wire enters the lug terminals parallel to the handle action, helping distinguish this configuration when comparing replacement breakers.
• Replacement-Focused Selection: Compare the part number, ratings, dimensions, connection style, and wire-entry orientation with the existing breaker and equipment requirements.

Material Compliance and Certifications

The available MDA200 specifications did not include specific material-compliance and certification information. Do not assume UL, IEC, RoHS, REACH, or other certification and compliance details based on similar products. Where a particular listing or compliance requirement applies, verify it against authoritative documentation for the exact MDA200 part number.

Where It Works Best

The MDA200 200 amp circuit breaker is intended for compatible existing or legacy residential electrical equipment calling for a 200A, 2-pole, 120/240VAC MD-A plug-in main residential thermal magnetic circuit breaker with a 10k A.I.C. rating.

For replacement work, pay particular attention to the connection arrangement. The MDA200 is specified with wire entering the lug terminals parallel to the handle action. That orientation, together with the 2.00"W x 6.31"L x 3.25"D dimensions, should be checked alongside the electrical ratings and MD-A type.
