Q2M2225MB - 225 Amp Circuit Breaker

Q2M2225MB - 225 Amp Circuit Breaker

When you're replacing a circuit breaker in older electrical equipment, the small details matter just as much as the amp rating. The Q2M2225MB is a 225-amp, 2-pole thermal-magnetic circuit breaker rated at 10 kA I.C. at 120/240 VAC. It has a non-interchangeable trip unit, with 1/4"-20 studs on the line side and lug terminals on the load side. The breaker measures 6.5 inches high, 3 inches wide, and 3.13 inches deep. If you're matching an existing Q2MB breaker, check the dimensions and connection points before installation. This breaker is primarily suited for repair and maintenance work where an existing electrical system requires the same form, fit, electrical ratings, and terminal arrangement. It's a straightforward component that's built to last when used within its specified ratings and installed in compatible equipment.

Key Features and Benefits

• 225 amp rating for applications designed around this specific current rating.
• 2-pole design for compatible 120/240VAC electrical equipment.
• Thermal-magnetic trip operation provides overcurrent protection.
• Rated 10 kA.I.C. at 120/240VAC.
• Non-interchangeable trip unit maintains the breaker's specified trip configuration.
• 1/4"-20 line-side studs with load-side lug terminals.
• Q2MB type helps identify the breaker when matching components in existing equipment.
• Compact dimensions of 6.5" H x 3.0" W x 3.13" D make physical comparison with the existing breaker easier.
• Designed for applications where matching the original breaker's form, fit, and function is important.
