E-T-A Circuit Breakers announced the PR60 and PR80 Power Relays as the
latest addition to its products specifically designed for the commercial
vehicle market. The PR60 is a monostable relay containing one coil and one
resting position. The PR80 is a bistable relay containing two coils and two
resting positions—it is switched ON through an impulse and remains in the ON
position until it is switched off by an additional impulse. The PR60 and PR 80
are designed for continuous loads up to 300A and current peaks up to 2400A—making the products suitable for single-pole switching of large loads in
construction and agricultural equipment. The relays can be operated from the
driver's cabin and protect the circuit by means of physical isolation.
PR60 and PR80 are environmentally sealed with protection standards of IP67
which offers a high level of protection against water or dust access. Additionally,
with a shock rating of 40 g and
vibration rating of 6 g, the PR 60
and PR 80 are optimal for use in the most physically demanding applications. Main
load connections are by means of M8 (100 A and 200A) or M10 (200A and 300A)
stud terminals with an insulating barrier between the terminals to protect
against accidental shorting when the cables are connected.
PR60 and PR80 power relays are available in voltage ratings 12, 24 and 48V and
are ideally suited for use as a battery disconnect relay or for switching other
high current circuits in trucks, buses, construction machinery and special
PR60 and PR80 power relays are available with a standard lead time of 6 - 8
Imagine being able to illegally download a physical product the same way you can with music and videos. That’s basically what’s happening with 3D printing and digital manufacturing, with huge repercussions in the intellectual property domain.
Ford will be the first automaker to commercially use Alcoa's tough & fast Micromill aluminum alloy process and materials, debuting on several 2016 F-150 truck components. Alcoa will also license its Micromill process and materials technology to Danieli Group.
