Q2M3150 - 150 Amp Circuit Breaker

Q2M3150 - 150 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the small details matter. The Q2M3150 is a 150-amp, 3-pole thermal-magnetic circuit breaker with a 10 kAIC rating at 240 VAC. It's a Type Q2M breaker and uses a non-interchangeable trip unit.

One detail worth checking closely is the connection setup. The Q2M3150 has 1/4-20" studs on both the line and load sides. That's an important point when you're trying to match the breaker already installed in a panel or other compatible electrical equipment. Physically, the breaker measures 6.5" high, 4.5" wide, and 3.13" deep.

If you're working on an existing or legacy system that calls for a Q2M3150, this breaker offers the specific combination of size, amperage, poles, interrupting rating, and stud connections associated with that part number. It's built to last when properly installed and used within its specified ratings. As with any replacement circuit breaker, check the complete specifications against the existing breaker and equipment, not just the amp rating, to make sure the form, fit, and function are correct.

Key Features and Benefits

• 150 amp rating for applications designed around this specific breaker capacity.
• 3-pole configuration for compatible three-pole electrical systems.
• Thermal-magnetic operation provides overcurrent protection using thermal and magnetic trip characteristics.
• Rated 10 kA at 240VAC.
• Non-interchangeable trip unit with a fixed breaker configuration.
• 1/4-20" studs on the line and load sides, an important detail when matching an existing installation.
• Type Q2M construction for equipment requiring this breaker style and configuration.
• Clearly defined dimensions make it easier to compare the breaker with an existing unit.

Material Compliance and Certifications

• Specific material compliance, certification, and agency listing information was not included with the available Q2M3150 specifications. Because certification requirements can vary by equipment and application, they shouldn't be assumed. Check the markings on the breaker and applicable product documentation when a particular listing, certification, or material standard is required.

Where It Works Best

• The Q2M3150 circuit breaker is intended for compatible electrical equipment that requires its specific Q2M form factor, 150-amp rating, 3-pole configuration, and 10k AIC rating at 240VAC. It is especially relevant when maintaining existing or legacy electrical systems where matching the original breaker's physical and electrical characteristics is important.
