Connectwell Jumper Bars: Faster, Cleaner Panel Wiring

Daisy-chaining with wire loops creates three consistent problems in control panel builds: time consumption, wasted duct space, and multiple potential failure points caused by inconsistent torque. Connectwell jumper bars remove all three.

The JX and JY jumper systems replace multiple wire links with a single component. Installation takes seconds, panel layouts stay clean, and long-term reliability improves. Charter Controls stocks the full range for next-day mainland UK delivery.

CP vs CY Terminal Blocks: Selecting the Right Platform

Connectwell offers two core termination technologies, each suited to different applications.

CP Series (Push-In Spring Clamp)
Pre-stressed stainless steel springs secure the conductor without tools. This significantly reduces wiring time and provides inherent resistance to vibration. Ideal for high-volume panel builds using ferrules. Shop CP Series terminal blocks.

CY Series (Screw Clamp)
Designed for high-torque mechanical termination. The guided entry ensures correct conductor placement, delivering a secure, gas-tight connection with large contact area. Preferred for power circuits and applications requiring torque verification. Shop CY Series terminal blocks.

Both series are fully compatible with Connectwell jumper systems, so your termination choice does not limit your bridging options.

Why Jumper Bars Replace Daisy-Chaining

Jumper bars bridge multiple terminals in a single action. There is no wire preparation, no crimping, and no torque variability between connections.

This delivers:

• Faster installation
• Reduced panel clutter
• Consistent electrical performance
• Fewer potential failure points

JX and JY jumper bars also support dual-row bridging, allowing separate circuits or grouped potentials on the same terminal strip. This is particularly useful in compact control panels where space and clarity matter.

Integrated Marking for Clear Identification

Each jumper bar includes a recessed marking area. This allows direct labelling with a felt-tip pen at the point of installation.

Clear circuit identification reduces commissioning time and improves maintenance efficiency, especially in densely populated DIN rail assemblies.

The Skip-Terminal Technique

Standard jumper bars connect consecutive terminals. When non-adjacent terminals need to be linked, the skip-terminal technique provides a simple solution.

Intermediate contacts can be removed using pliers. The remaining insulated structure maintains touch safety while allowing selective bridging.

This avoids the need for custom parts and produces a cleaner result than additional wiring.

Step-Down Jumpering for Mixed Terminal Sizes

Connecting different conductor sizes on the same DIN rail often introduces unnecessary components such as distribution blocks.

Connectwell step-down jumpers, including the JXS series and CA801/8, allow direct connection between terminal sizes. A common example is linking 6mm² power terminals to 2.5mm² control terminals using the JXS6/2.5.

This approach reduces component count, simplifies layout, and shortens build time. Browse DIN rail terminal accessories including step-down jumpers.

Frequently Asked Questions

What is the difference between CP and CY terminal blocks?

CP series use push-in spring clamps for fast, tool-free wiring and vibration resistance. CY series use screw clamps for high-torque, mechanically secure connections suited to power applications. View both ranges.

How do I connect non-adjacent terminals?

Use the skip-terminal technique by removing intermediate contacts from a standard jumper bar. This allows selective bridging without custom parts.

Can jumper bars connect different terminal sizes?

Yes. Step-down jumpers such as the JXS series connect terminals of different sizes directly, eliminating the need for distribution blocks.

Are Connectwell products available in ePlan?

Yes. Full integration is available, including jumper logic and terminal configurations for accurate design and documentation.

Are ATEX versions available?

Yes. ATEX-certified variants are available to order for hazardous environments.
