UL Listed,IP-20 Enclod Power Distribution Block Offer High SCCR
绿豆芽怎么做New 2005 NEC ®and UL508A SCCR marking requirements state that the following equipment must be marked with an asmbly SCCR:• Industrial Control Panels [409.110]
儿白是什么意思• Industrial Machinery Electrical Panels [670.3(A)]• Certain HVAC Equipment [440.4(B)]
This SCCR is bad on the lowest-rated component, or weakest link,in the asmbly. Unmarked power distribution blocks will default to a rating of 10kA. The new Cooper Bussmann ®enclod Series PDBFS offers both high SCCR and enhanced shock protection.我们不是只有现在吗
• UL Listing Meets Requirements Eliminating Investigation and Procedures
Listed to UL1953 for minimum spacing requirements of at least 1˝through air and 2˝ over surface as required for UL508A industrial control panel feeder applications. See back page.
• High SCCR
Up to 200kA rating enables the power distribution block to be one of the highest rated devices in the panel. This helps achieve a high asmbly SCCR.
• Enclod for Enhanced Electrical Safety眼睛部位图解
精加工策略Safer work conditions. IP-20 finger-safe under specific conditions.
• Easy Panel Mounting
Gangable for flexible multi-pole installations, plus small footprint for tight spacing.
• Simple and Fast Installation
DIN rail mount or panel mount, (See datasheet 1049). Captive terminal screws are backed out at the factory.

UL Listed 1953 vs.UL Recognized 1059
Listed products require simply checking to ensure that the product is ud in accordance with its listing and labeling.However ,for recognized products,such as power terminal blocks,the “Conditions of Acceptability”must be
investigated to ensure the product is suitable for the specific application,and then the procedure description must be documented in the manufacturer’s procedure for the asmbly .
