A manufacturer of electrical and electronic components for circuit protection and connections has introduced its UL Listed Thermoplastic 135 Series Power Distribution Blocks. The 135 Series Power Distribution Blocks, from Marathon Special Products, include a high current carrying capacity, wide range of wiring options, and suitability for UL508A Control Panel Applications up to a Short Circuit Current Rating of 100,000 SYM Amps. Most company products comply to UL requirements for use with flexible stranded wires, carry short-circuit current ratings, and are CE 1,000 Vac and Vdc rated.

The 135 Series meets UL1953 (Power Block standard) requirements and is listed for general installation. This means they have adequate spacing for most OEM and field applications. The advantage of using a 135 series distribution block can be used in “as supplied condition” because it meets the feeder circuit terminal spacing requirements per UL508A section 10.2 (1 in. through air and 2 in. over surface at 600V). The blocks are identified with a listing mark from UL so inspectors need not check “conditions of acceptability” resulting in a quicker inspection.

The Power Distribution Blocks also comply with National Electric Codes for use in service equipment. The blocks are UL Listed and service-equipment rated, so they are suitable for applications where system components must be connected in the field. This includes installation in wireways and industrial control panel feeder/branch circuits, splicing and tapping conductors in metallic wireways, auxiliary gutters, junction boxes, termination boxes, and similar applications. The blocks can also connect modular tower sections for wind turbines, for large motor connections such as water lifting and material handling, and to interconnect multiple panels in control and power-distribution systems.
