267A42-6

Terminal Blocks - Accessories - Jumpers

The 267A42-6 Jumper Bar has a wide range of uses in electrical engineering and automation technology. It is suitable for use in the control cabinet, in the switch cabinet, and in the control panel. The device can be used in the control of starters, switches, and reversing starters.

It is designed to be used for linking and bridging two contact points for continuous currents of up to 250 A as well as making improved connections among wires, terminals, and blocks in the control cabinet. There are two sizes available, each with the same working principle of connecting two contact points.

The 267A42-6 Jumper Bar consists of two aluminium extrusion bars that can conduct up to six control circuits of 250 A each. The two bars are spaced to create a contact bridge between the two points. The contact bridge acts as an electrical connection to allow the current to pass between the two points.

Working Principle

The working principle of the 267A42-6 Jumper Bar is simple. First, the two aluminium extrusion bars are placed across the two points that need to be connected. The bars are spaced in order to create a conductor bridge between the two points. When the bars are placed, they form an electrical connection between the two points which allows the current to pass between them.

In addition to providing an electrical connection, the bars also serve to protect the two points from electrical arcing which can occur between circuits when they are placed too close together. The bars also serve to distribute the current more evenly and thus, reduce resistance. This helps to ensure that the current is passed evenly, which increases the efficiency of the circuit.

Application Field

The 267A42-6 Jumper Bar can be used in a wide range of applications, including control cabinets. It is suitable for starter control applications, and for linking and bridging two contact points in starter or reverse starter switch systems up to 250 A.

It is also suitable for linking and bridging two contact points in other switch systems, including those that are designed to control lighting, motors, or other electrical systems. The device is also used to make improved connections between wires, terminals, and blocks in the control cabinet.

Because of its versatile uses and benefits, the 267A42-6 Jumper Bar is widely used in a wide range of electrical engineering and automation systems.
