Blue Sea Systems ST CLB Circuit Breaker Block Jumper

The Blue Sea Systems ST CLB Circuit Breaker Block Jumper is a small accessory that snaps into any position on a Blue Sea ST CLB Circuit Breaker Block the same way a CLB breaker does — but instead of providing overcurrent protection, it simply bridges that position to the block's common source bus.

Key details

• Snaps in using the same quick-connect clips as a CLB breaker
• Sold 5 per retail package
• Works with all Blue Sea ST CLB Circuit Breaker Blocks

Use it when a circuit breaker block position needs to carry power through to a downstream connection without its own dedicated overcurrent protection — for instance, bridging one position to feed a sub-bus, or filling a spare position so it stays electrically connected for future expansion without leaving a breaker installed unnecessarily.

Keep a few of these on hand alongside spare CLB breakers when wiring or servicing a panel built around Blue Sea's ST CLB blocks (PN 5050-5054) — they're inexpensive, and running out mid-installation means an otherwise-finished circuit breaker block sits with an open position until a jumper or breaker is available. It's a low-cost accessory worth keeping a few spares of alongside CLB breakers whenever you're installing or servicing a panel built around Blue Sea's ST CLB circuit breaker block family, so an open position never has to sit unusable while you wait on a part. Order a handful along with your initial breaker block purchase rather than waiting until you need one mid-project, since it's a small enough part to be easy to lose track of.
