MA36300 - 300 Amp Circuit Breaker Description
MA36300 - 300 Amp Circuit Breaker
When you're replacing a circuit breaker in existing equipment, the nameplate details matter. The MA36300 is a 300 amp, 3-pole MA molded case circuit breaker for I-Line panelboards, with thermal-magnetic operation, a 60Hz frequency rating, and a 40°C rating. When its electrical ratings, MA type, I-Line panelboard application, dimensions, and other installation requirements match the equipment being serviced, the MA36300 can be considered a form, fit, and functional replacement candidate.
Key Features and Benefits
- 300 Amp Rating: Rated at 300A, making amperage straightforward to verify against the existing breaker and equipment requirements.
