Hylec's New 80A Isolator Switches Ensures Fast Electrical Isolation for Multiple Applications

September 13, 2017

 

80A Isolator

Hylec-APL, the specialist supplier of electrical components and enclosures, announces new model in its range of Isolator switches, which provide fast electrical isolation for multiple applications, including industrial machinery, commercial buildings, power supplies, security equipment and HVAC. Isolator control switches are IP67 rated and withstand water up to a depth of one metre, as well as completely preventing the ingress of dust and dirt, vital in many factory and commercial applications.

Safety is of paramount importance in such environments, and Isolator control switches ensure an electrical circuit is completely de-energised for routine service and maintenance and can be shut down quickly in the unlikely event of an emergency. The Isolator switch separates the circuit from the main power source and discharges any current trapped in the circuit, rendering it safe to work on and of course ensuring fast shut down and the absence of any electrical current when an emergency stop is required. When used as an emergency stop, it can be locked in the off position using a padlock (not supplied). For safety, the switch is interlocked with the lid to prevent opening while in the “on” position. The interior mechanism is a 4-pole rotary isolator switch disconnector used to switch power to commercial or light industrial applications.

Isolator control switches are manufactured from completely flame retardant polycarbonate, rated to UL94V-0, providing an additional margin of safety over competitive products with a lower flame-resistance rating. As well as being flame retardant, housings are robust and highly visible, with yellow covers and red control switches. The new 80A AC Isolator model features silver-plated alloy contacts for high reliability. Earth terminals are included, as well as captive retained cover screws. The 80A AC Isolator has a compact footprint, but its internal dimensions are a generous size, measuring 9cm wide by 17.3cm long, so there is space to manipulate cables easily during installation.

Schurter Is Ready! . . . for the New Requirements of IEC/EN 60127-6 Edition 2 Increased Glow Wire Resistance

September 5, 2017

Schurter Logo1.jpg

The new fuse holder standard IEC/EN 60127-6 Edition 2, requiring increased glow wire resistance, will come into effect the beginning of October 2017. Schurter is ready!

Glow Wire

With the updated fuse holder standard IEC / EN 60127-6 Edition 2, more attention is given to the area of fire protection. New requirements focus on the materials being used, which must be glow wire tested according to IEC / EN 60695-2-12 and -13 (GWIT=775°C and GWFI=850°C).

These new requirements are contained in the standard for household appliances IEC/EN 60335-1, which has been a long time established standard, particularly due to the prevalence of such unattended appliances (e.g., coffee machines).

All manufacturers of fuse holders must therefore check the glow wire resistance of the materials being used and, if necessary, replace the material. It is also necessary to update the approvals and to carry out a re-examination by the certification body. In case of a material change, the tests according to UL 4248.1 must also be repeated.

All fuse holders certified Until October 08 2017, SCHURTER will have adapted the complete range of its IEC-certified fuse holders to the new standard, including power entry modules with fuse holders. This will poise SCHURTER as the first manufacturer of fuse holders ready to meet the stringent standard.

All Schurter IEC-certified fuse holders marketed as of October 08 2017 will comply with IEC/EN 60127-6 Edition 2, as well as UL 4248.1, and can therefore be safely installed in all household appliances.

Customer-friendly Schurter has placed great attention on the fact that the same part numbers will be used. This makes it unnecessary for the user to make changes to a parts lists, or be deal with new approvals.

General Rules from VDE
-  The manufacturer will lose VDE approval after October 08 2017 for any parts that do not conform with the new requirements for IEC / EN 60127-6 Edition 2 and therefore must no longer sell those products.

-  All parts the manufacturer already sold to market (i.e. to end-customers, distributors or resellers) before October 08 2017 maintain valid VDE approval.

-  All mixed inventory at end-customers, distributors or resellers can continue to be used or shipped or resold without any limitation.

Schurter USN 1206 Temperature Sensitive SMD Fuse

August 30, 2017

Schurter Logo1.jpg

* Customer-specific time-current tripping characteristic as a function of ambient temperature
* Combination of protection against overcurrent and excessive ambient temperature
* On request qualified according to AEC-Q200

USN 1206

Schurter’s USN 1206 offers a temperature-sensitive SMD fuse suitable for both overcurrent protection and protection against excessive ambient temperatures.

Due to the ever-increasing packing density in power electronics, it is becoming ever challenging to deal with the resulting tighter and hotter board real-estate. Automobile manufacturers increasingly use control units in their products, including power electronics (e.g. ABS modules, annealing time control units and actuators). The trend is to integrate as many functions as possible into the smallest possible space in a single module. The fact that such modules must be protected against overcurrent is self-evident. However, the increasing power density also entails thermal requirements. For this purpose, new approaches are needed to avoid a creeping risk of overheating.

Combination: Current and Temperature

The USN 1206 from SCHURTER is not a pure thermal fuse. It requires a current flow to blow, thus providing protection against overcurrent just as well as any conventional fuse. In addition, it is also designed to protect power semiconductors in automotive applications against over temperature. The fuse has a current-time characteristic which shifts as a function of the ambient temperature. As a result, a specific trigger at a certain threshold value can be achieved increasing temperature.
The USN 1206 from SCHURTER has high I2t values at 32 VDC and a slow blowing characteristic.

Reflow Solderable
The USN 1206 temperature-sensitive SMD fuse is reflowable at 245°C according to IEC 60068-2-58. The epoxy glass housing makes it tight against the potting compound. Thus, the fuse is also suitable for explosion-proof applications according to ATEX / IECEx.

Application Areas
The production and qualification of the fuse is carried out in agreement with the customer according to the requirement profile of the desired time-current trip characteristic as a function of the ambient temperature. The new Schurter USN 1206 is particularly suitable for automotive applications requiring the highest reliability under particularly difficult conditions (heat, vibration, mechanical and cyclic strength). In addition, it is also used wherever temperature-critical processes occur, or even when a specific intrinsic characteristic is required.

Technical Data / Approvals
- Certification and Qualification on Request (AEC-Q200, UL, IEC, MIL)
- Combination of protection against overcurrent and excessive ambient temperature
- Customer-specific time-current tripping characteristic / temperature
- High I2t values
- Rated current: 12 A (USN 1206 12 A , customer-specific)
- Rated voltage: 32 VDC
- Slow blowing characteristic

Applications
- In all electronics with temperature-critical components (eg Mosfet's)
- Automotive
- Intrinsically safe
