The LV848166: Rear bottom connection assembly for MasterPact drawout breakers. This accessory bolts onto the downside of the breaker, giving you a vertical rear connection point for 4-pole circuits. The 115 mm pitch lines up with the standard bus stack. Fix it where it sits — no need to pull the whole bucket.
Mounting and fit
Mounts on the downside of the breaker with a drawout fixed chassis. Connection position is vertical, accessible from the rear — saves you from having to crawl behind the panel to land cables. The 115 mm pitch is the same across the MasterPact line, so it swaps into existing cubicles without re-drilling.
