Frequently Asked Questions (FAQ)

Q: Are parts 2907530 and 2907598 direct replacements for 2907666? A: Yes. All three parts share identical electrical ratings (25A, 480V AC, 125V DC), breaker type (thermal magnetic), mounting configuration (DIN rail, two-pole, lever actuation), and series designation (TMC 8). They are parametric equivalents and functionally interchangeable.

Q: What determines substitution eligibility for these circuit breakers? A: Substitution is based on matching current rating, AC and DC voltage ratings, breaker type, number of poles, actuator type, and DIN rail mounting specification. All three parts meet these criteria identically.

Q: Do all substitute parts meet the same compliance standards? A: Yes. Parts 2907666, 2907530, and 2907598 all carry ROHS3 compliance and REACH unaffected status. They are suitable for applications with identical regulatory requirements.

Q: Is there a difference in packaging between these parts? A: No. All three parts are supplied in box packaging.

Q: Can I use these parts interchangeably in existing installations? A: Yes, provided the installation uses DIN rail mounting and requires a two-pole, 25A thermal magnetic breaker rated for 480V AC and 125V DC operation. The lever actuation and electrical characteristics are identical across all three parts.
