Parts 2907550 and 2907686 maintain standard RoHS compliance. All three parts are classified under the same ECCN and HTSUS codes, indicating equivalent trade and export status. Inventory levels are comparable across all three options, with 910 units of 2907550, 1165 units of 2907617, and 917 units of 2907686 currently available.

Frequently Asked Questions (FAQ)

Q: Are parts 2907617 and 2907686 direct replacements for 2907550?

A: Yes. All three parts are parametric equivalents with identical current ratings (13A), voltage ratings (480V AC / 125V DC), pole configuration (3-pole), breaker type (thermal magnetic), mounting method (DIN rail), and actuator type (lever). They are functionally interchangeable in applications requiring these specifications.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the most current RoHS directive implementation. Part 2907617 carries ROHS3 certification, while 2907550 and 2907686 carry standard RoHS compliance. Both certifications indicate compliance with hazardous substance restrictions; ROHS3 reflects alignment with the latest regulatory requirements.

Q: Do all three parts use the same DIN rail mounting standard?

A: Yes. All three parts are designed for standard DIN rail mounting with identical mechanical interfaces and lever actuation, ensuring compatibility with the same installation infrastructure.

Q: Are there any differences in packaging or inventory status?

A: All three parts are supplied in box packaging. Inventory levels differ slightly: 2907617 has the highest availability at 1165 units, followed by 2907686 at 917 units, and 2907550 at 910 units.

Q: Can these parts be used interchangeably in existing installations?

A: Yes, provided the installation uses standard DIN rail mounting and requires the specified electrical parameters (13A, 480V AC / 125V DC, 3-pole thermal magnetic protection). Physical dimensions and mounting interfaces are identical across all three parts.
