JD63B225 - 225Amp Circuit Breaker

JD63B225 - 225Amp Circuit Breaker

The Siemens JD63B225 is designed for installations that require a specific set of breaker characteristics: 225 amps, three poles, a JD frame, and a 600V rating. The breaker measures 7.5 inches wide, 11 inches high, and 4 inches deep, so those dimensions are worth checking carefully when you're matching it to existing equipment. The JD63B225 is built to last and is well-suited to replacement work where maintaining the correct form, fit, ratings, and connection arrangement is the priority.

Key Features and Benefits

• 225A, 3-pole breaker with clearly defined ratings for replacement matching.
