A manufacturer of electrical and electronic components for circuit protection and connections has introduced the UL Listed Thermoplastic 135 Series Power Distribution Blocks. These 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. 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. In addition, the 135 Series 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, 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.
