Eaton 101452 Adaptador de barramento de 45mm 32A 2 polos BBA0-32

In industrial control panels and distribution boards, the Eaton BBA0-32 busbar adapter provides a direct connection point for 2-pole modular devices onto 45 mm pin busbar systems. Rated for 32 A, it allows installers to tap power without additional wiring, reducing assembly time and potential connection errors.

Why choose it

The adapter's screw terminals accept conductors up to 25 mm², accommodating a wide range of load wiring. Its thermoplastic housing provides insulation and mechanical stability, while the 45 mm pitch matches standard busbar layouts for compatibility with Eaton xPole modular devices.

Ideal use cases

• Feeding power to circuit breakers, residual current devices, or other modular components in distribution boards
• Retrofitting existing busbar systems with additional outgoing circuits
• Industrial control panels where space is limited and direct busbar tapping is preferred

Good to know

The adapter is designed for pin busbar systems and mounts directly onto the busbar without tools. It is rated for indoor use with an IP20 protection degree at the terminals, so it should be installed inside an enclosure.
