MAL36300 - 300 Amp Circuit Breaker

MAL36300 - 300 Amp Circuit Breaker

Finding the right breaker for your existing electrical equipment comes down to matching the key details. The MAL36300 is a 300 amp, 3-pole MAL thermal magnetic molded case circuit breaker rated for 60Hz operation and 40 °C. For legacy equipment with the same electrical and physical specifications, the MAL36300 can be considered a form, fit, and functional replacement candidate. Its solid molded-case construction is built to last when the breaker is properly selected, installed, and maintained.
