The ABB 1SNA684252R0200 (model BJMI8-10) is a high-quality fractional jumper bar designed for the SNA series of terminal blocks. This component is engineered to facilitate the electrical interconnection of multiple terminal blocks, streamlining wiring and ensuring consistent potential distribution across a terminal assembly.
Technical Specifications
- Series: SNA series terminal block accessories.
- Model Type: BJMI8-10 (10-pole jumper).
- Spacing: Designed for terminal blocks with 8 mm spacing.
- Current Capacity: Rated for industrial currents compatible with the associated terminal blocks.
- Mounting: Screwed jumper bar that ensures a secure, vibration-proof electrical connection.



Primary Functions
- Potential Distribution: Allows a single power or signal input to be distributed across ten adjacent terminal blocks simultaneously.
- Space Optimization: Replaces multiple individual wire bridges, significantly reducing cabinet clutter and potential wiring errors.
- Reliability: Provides a low-resistance path that maintains electrical integrity even in environments subject to mechanical stress.
Applications
Widely utilized in industrial control cabinets, power distribution boards, and PLC interface modules. It is an essential component for technicians and engineers looking to simplify the assembly of DCS I/O racks or complex motor control center (MCC) wiring systems.
