Eaton’s Class J fuse block with power distribution capability by Bussmann uses up to 50% less panel space and decreases installation time and labor by 33% by reducing the number of components required in the circuit. Courtesy: EatonA new power distribution Class J fuse block was introduced by the Bussmann business of power management company, Eaton (NYSE: ETN). The fuse block with power distribution capability uses up to 50% less panel space and decreases installation time and labor by 33% by reducing the number of components required in the circuit. The patented product is available with 100 A, 200 A, and 400 A ratings, appropriate for heating, ventilation, and air conditioning applications.

"Our newest solution represents an industry-first, combining a power distribution block with a Class J fuse block to help enhance overall system integrity," said Darren McDowell, product manager, Eaton's Bussmann division. McDowell told CFE Media editors the new power distribution Class J fuse block reduces component count and saves control panel real estate, two key customer concerns. He expects the product to be especially well received in HVAC applications, at UL508 panel shops, at equipment manufacturers, and anytime an electrical line branches into multiple circuits. Customers, who were consulted for the design, have received the product very positively, he said.

The new power distribution fuse block is available in 1-, 2-, and 3-pole versions with individual pole versions having a dovetail feature that allows point-of-use assembly depending on the number of poles. With a smaller footprint and a 200 kiloamps (kA) withstand rating, the product helps panel builders achieve a higher assembly short circuit current rating (SCCR) for compliance with National Electric Code Sections 110.10, 409.22, 440.4(B), 670.3(A)(4), and 670.5. In addition, products offer a voltage (V) rating of 600 V and a Class J fuse amperage (A) range of 70 A to 400 A.

To help enhance safety and help maintenance personnel, products offer optional finger-safe, see-through covers, an IP20 (Ingress Protection) rating that includes lockout/tagout (LOTO) capabilities, and open-circuit indication. In addition, all power distribution fuse blocks are Underwriters Laboratories (UL) recognized to E14853 - IZLT2, CSA certified to 47235 - 6225-01, and with covers are UL Listed to E58836 - JDVS2.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
