ABB THQMV175D - 175A, 2-Pole, Circuit Breaker

Meet the ABB THQMV175D—a rugged 175A, 2-pole circuit breaker engineered for dependable overcurrent protection in demanding electrical environments. Ideal for industrial, commercial, and OEM applications, this device is purpose-built to keep distribution panels, switchboards, and control panels safe and reliable.

• 175A current rating provides robust protection for high‑amperage feeders and critical circuits, helping prevent damage from overloads and short circuits.
• 2-pole configuration ensures both conductors trip together on a fault, minimizing arc exposure and enhancing overall safety in your installation.
• Versatile installation designed for panelboards, switchboards, and control panels, enabling streamlined protection across a wide range of sites and setups.
• Industrial-grade reliability built to perform in demanding environments where uptime and safe operation are non-negotiable.
• OEM-ready and scalable a practical fit for new builds and retrofits, integrating smoothly into ABB and compatible protection schemes in motor control centers (MCCs) and distribution architectures.

The THQMV175D excels where strong, predictable protection matters: protecting feeders, safeguarding motor circuits, and ensuring that a fault doesn’t propagate through an entire system. It’s a practical choice for distribution panels and MCCs that require rapid, reliable isolation to minimize downtime and equipment risk.

Key use cases

• Main protection for large feeders in panelboards and switchboards.
• Protection for motors and motor control centers in industrial environments.
• OEM equipment protection within packaged systems and integrated power solutions.

How to select and use

• Verify that 175A is appropriate for your circuit load and that the panel’s rating accommodates a 2-pole device of this size.
• Confirm compatibility with your protection scheme and installation hardware, following the manufacturer’s guidelines for mounting and electrical connections.
• Plan for routine inspection and replacement after fault events to maintain protection integrity and system reliability.
