MD150H - 150A Circuit Breaker

MD150H - 150A Circuit Breaker

The MD150H is a sturdy 150 amp, 2-pole circuit breaker designed for residential use. It’s ideal when you need compatibility in electrical ratings, plug-in type, lug arrangement, and size with your existing equipment.

Key Features and Benefits

• 150 Amp, 2-Pole Rating: Provides the amperage and pole configuration needed to match compatible residential electrical equipment.
• Type MDH: The MDH designation is an important identifier when checking compatibility with an existing installation.
• Plug-In Configuration: Designed as a plug-in breaker, making this characteristic an essential part of the form-and-fit check.
• Main Residential Circuit Breaker: Specifically identified for main residential applications.
• Thermal-Magnetic Operation: Uses the thermal-magnetic circuit breaker configuration specified for this model.
• Staggered Lug Arrangement: The MD150H uses staggered lugs, a physical detail to match carefully during replacement selection.
• Perpendicular Wire Entry: Wire enters the lug terminals perpendicular to the handle action, helping distinguish this configuration from similar breakers with a different terminal orientation.

Material Compliance and Certifications

The supplied product information confirms that the MD150H uses staggered lugs and that the wire enters the lug terminals perpendicular to the handle's action. No specific lug material, conductor material compatibility, approved wire range, or terminal torque information was provided. Check those characteristics against appropriate product documentation when relevant to the installation.

No specific UL, IEC, RoHS, REACH, or other certification or material-compliance information was supplied for this part. Rather than assume a listing or compliance status, verify any required certification against appropriate documentation for the MD150H.

Where It Works Best

The MD150H is a practical replacement candidate for compatible existing or legacy residential electrical equipment that requires a 150A, 2-pole Type MDH main circuit breaker with a plug-in configuration, thermal magnetic operation, 120/240VAC voltage rating, and 10k A.I.C. rating.

Check one important physical detail before treating two similar MDH breakers as equivalent. On the MD150H, the lugs are staggered, and the wire enters the lug terminals perpendicular to the handle's action. That terminal orientation should match the requirements of the existing equipment rather than being assumed from amperage or breaker type alone.
