Marathon Special Products series of UL Listed Power Blocks feature high current carrying capcity (up to 950A), a wide range of wiring options, hinge cover, and suitability for UL 508A Control Panel Applications with Short Circuit Current Rating (SCCR) up to 100,000 SYM Amps.
According to James Hemp, Sr. Project Engineer at Marathon Special Products, “the advantage of using a 135 series listed Power Distribution Block versus a recognized block is that a listed block (UL1953) can be used in “as supplied condition” since it meets the feeder circuit terminal spacing requirements per UL508A section 10.2 (1” through air and 2” over surface at 600V).”
The 135 Series Power Distribution Blocks comply with National Electric Codes (NEC) for use in service equipment. Since these blocks are UL Listed and service equipment rated, these blocks are suitable for applications where system components must be connected in the field. This includes installation in wireways, junction boxes, termination boxes, and similar applications. Applications of the 135 series Power Blocks include connection of modular tower sections for Wind Turbines, large motor connections, and interconnection of multiple panels in control and power distribution systems.
