Marathon 1353702, 3 Pole Power Distribution Block, 950 Amps, 2 Line Side & 2 Load Side Opening, UL Listed For Feeder Circuit Terminals, Please Choose Options
We are pleased to introduce our new UL Listed Thermoplastic 135 Series Power Distribution Blocks. The features of the 135 Series Power Distribution Block include high current carrying capacity, wide range of wiring options and suitability for UL508A Control Panel Applications up to Short Circuit Current Rating (SCCR) of 100,000 SYM Amps. The 135 Series Power Distribution Blocks have been investigated to meet UL1953 (Power Block standard) requirements and are listed for general installation. This means that they have adequate spacing for most OEM and field applications.
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). Since these blocks are identified with a listing mark from UL, the inspector would not need to check "conditions of acceptability" resulting in a quicker completion of inspection.
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 industrial control panel feeder/branch circuits, splicing and tapping conductors in junction boxes, termination boxes, and similar applications. They can also be used in connection of modular tower sections for wind turbines, for large motor connections such as water lifting and material handling, and for interconnection of multiple panels in control and power distribution systems. The majority of Marathon’s products have been tested and comply to UL requirements for use with flexible stranded wires, have short-circuit current ratings (SCCR) and are CE 1000 Volt AC/DC rated.
