UL Listed Power Distribution Blocks from Marathon

456

Marathon Special Products has released a new series of UL listed power blocks. The features of the 135 Series Power Distribution Block include high current carrying capacity (up to 950A), wide range of wiring options, hinge cover, and suitability for UL508A control panel applications with short circuit current rating (SCCR) up to 100,000 SYM amps.

According to James Hemp, senior project engineer, “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.”
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, they 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 include connection of modular tower sections for wind turbines, large motor connections, and interconnection of multiple panels in control and power distribution systems.

Its product offering includes fuse holders for power fuses, power distribution blocks, touch-proof power blocks, single and double row terminal blocks, heavy duty terminal blocks, and NEMA and DIN sectional terminal blocks.
