The EZAFSHB3 is a fishbone connector set of 3 from Schneider Electric's Easypact EZC100 series, designed to bus together the line-side terminals of up to three EZC100 circuit breakers in a common panel distribution block. Rated for 100 A and 3 poles, this connector lets you gang three single-breaker feeds into one incoming supply without individual jumper wiring — a clean, UL-compatible method for multi-circuit subfeeds inside a switchboard or MCC bucket. The device short name CVS100BS EZC100 GR12T identifies the specific bus-bar geometry and pitch that mates with the EZC100F, EZC100H, EZC100B, and EZC100N breaker frames.
What the 100 A rating means for fit
The 100 A rating is the continuous bus-bar current capacity of the connector set itself — not the breaker rating. It matches the frame size of the EZC100 breakers, so the connector does not become the thermal bottleneck in a 100 A subfeed. Because it is a 3-pole set, it buses all three phases simultaneously. In a 3-phase panel, one EZAFSHB3 set handles the A, B, and C phase connections across three breaker positions.
The fishbone connector mounts directly onto the line-side terminals of the EZC100 breakers — no DIN-rail adapter, no additional bus-bar kit. The three-piece set covers the full pole count for a three-breaker group. Verify the breaker terminal torque spec when tightening the connector.
