MD175H - 175A Circuit Breaker

MD175H - 175A Circuit Breaker

The MD175H is a reliable 175 amp, 2-pole Type MDH thermal magnetic circuit breaker designed for residential use with a plug-in configuration. With a 10 kA interrupting capacity at 120/240VAC, it’s easy to ensure compatibility with existing systems. If your current breaker matches the MDH type, amp rating, pole configuration, voltage, and design, the MD175H is a perfect fit.

Key Features and Benefits

• 175 Amp, 2-Pole Rating: Provides the clearly identified amperage and pole configuration needed when matching an existing breaker.
• Type MDH: The MDH designation is a key compatibility detail when evaluating the MD175H as a replacement.
• Main Residential Breaker: Specifically identified for main residential applications.
• Plug-In Configuration: The plug-in design is an important physical characteristic to verify against the existing equipment.
• Thermal-Magnetic Operation: Uses the thermal-magnetic trip configuration specified for this model.
• Staggered Lug Arrangement: The MD175H has staggered lugs, which matters when checking physical and conductor-entry compatibility.
• Perpendicular Wire Entry: Wire enters the lug terminals perpendicular to the handle, helping distinguish this configuration when matching an existing installation.

Material Compliance and Certifications

The supplied information confirms that the MD175H has staggered lugs and that the wire enters the lug terminals perpendicular to the handle action. Lug material, conductor range, terminal torque values, and other terminal specifications were not provided, so these characteristics should not be assumed.

The available specifications did not include any specific UL, IEC, RoHS, REACH, or other certification or material-compliance information. If a particular listing or compliance requirement applies to the installation, verify it with appropriate supporting documentation for the MD175H.

Where It Works Best

The MD175H 175 amp circuit breaker is best suited for compatible existing or legacy residential electrical equipment that requires a 2-pole, Type MDH plug-in main thermal magnetic circuit breaker. Electrical requirements should match the supplied 120/240VAC voltage rating and 10k A.I.C. rating.

For this model, don't stop at checking the 175A rating. The staggered lug arrangement and perpendicular wire-entry orientation are significant form-and-fit details. Compare them with the breaker being replaced, along with the 2.00 "W x 7.06 "L x 3.25 "D physical dimensions.
