Schurter Logo1.jpg

• Unique UL rating of 277 VAC
• Rocker actuated
• Various colour switches
• IP 65 with optional cover

With the TA35 series, Schurter offers a particularly versatile generation of miniature circuit breakers with a newly attained UL rating of 277 VAC, the North America rating for 1 of 3 phase used in lighting applications and other mains connected 1-phase devices. They are available in 1-, 2- or 3-pole versions and are especially impressive with their compact and attractive design.

The TA35 offers both the function of a ON/OFF switch and thermal overcurrent protection. Finely graduated rated currents are available from 0.05 A to 20 A for 1-pole and 2-pole circuit breakers, and 0.05 A to 12 A for 3-pole circuit breakers. An optional protective cover offers an IP 65 degree of protection, making the switch suitable for use in harsh environments exposed to dust and splashing water.

The rocker switch can be supplied with or without illumination in six colours with standard print legends, or customer-specific symbols. The circuit breakers are designed for efficient snap-in mounting in panel thicknesses from 1 to 4 mm. The terminals are quick-connect 6.3 x 0.8 mm.

Applications for the TA35, with its increased rating, are commercial lighting and power distribution. Other 1-phase mains connected applications include power generators, cleaning equipment, laboratory equipment for chemical and medicinal use, or machines for food service or processing.

Technical Data / Approvals
The rated AC voltage according to UL was increased to 277 VAC for all non-illuminated 1-pole and 2-pole versions. The voltage rating according to IEC remains at 240 VAC

In addition to the wide application areas of the TA35, the new rating of 277 VAC opens the following new possibilities:
• Industrial lighting arrays (277 VAC)
• Medical and laboratory equipment (277 VAC)
• Industrial Power (277 VAC)
– power supplies
– power distribution strips
– surge/transient voltage suppressors
– power conditioners
– step down transformers

Schurter UAI 1206 Chip Fuse

Schurter Logo1.jpg

Chip Fuse for Highest Demands
* Pulse- and temperature-resistant non-aging chip fuse
* Sealed against potting compound
* Meets requirements according to AECQ

With the UAI 1206, Schurter offers a pulse and temperature resistant chip fuse with time-lag characteristics for applications where durability and maximum reliability are requested.

Conventional fuses have a sort of memory. If they are exposed to pulse-shaped current peaks and high temperature fluctuations, their properties change. Every pulse makes the fuse a little weaker, every temperature fluctuation a little more susceptible. Not so with the Schurter UAI 1206.

 

Pulse and Temperature Resistance
Because of the a special fuse construction, dubbed by SCHURTER as “trace in air” technology, the UAI’s ability to resist current pulses smaller than the melting integral (I2t) is thereby increased exponentially. Comparably, the UAI 1206 has practically no derating to the usual extent. The ingenious design of the fuse body also dampens temperature fluctuations to a high degree. The SCHURTER UAI 1206 is also hermetically sealed against potting compound for use in intrinsically safe applications.

Areas of Application
The new chip fuse, which is offered in two versions with rated currents of 5.3 A and 7.5 A, was specificially developed for automotive applications. The Schurter UAI 1206 meets all requirements according to AEC-Q200. It is also suitable wherever high levels of pulse currents, high thermal fluctuations, and high mechanical loads are present.

Schurter DKIH-4 High Current Choke

Schurter Logo1.jpg

Common Mode Chokes for 4 line Applications mount on PCB
• Compact size and light weight
• Open design for optimal cooling
• Nanocrystalline ring cores
• Customer specific pin configurations available

Schurter expands its successful range of current-compensated chokes with a series for 4-wire high-current applications on printed circuit boards. The new DKIH-4 series is available for three phase applications with neutral line at rated currents from 10 A to 40 A. Due to the open design, the chokes are particularly compact and light.

Like most electronic assemblies, the power section is increasingly being mounted on the printed circuit board with discrete components. However, due to the high integration density required to achieve a compact design, thermal problems can arise due to the high currents on the PCB. EMC interference can affect adjacent modules due to the lack of spatial separation. Therefore, a compact filter on the PCB with discrete components is often the best solution. A current-compensated choke with capacitors is the most efficient method of suppressing EMC interference.

The new DKIH-4 series is suitable for three phase applications with neutral line from 10 A up to 40 A . Light weight and compact, the common mode chokes are easily placed on the PCB with through hole technology (THT). The common mode chokes are designed according IEC 60938 and rated 500 VAC or 760 VAC, making them suitable for almost any applications.

The DKIH-4 has been designed for a wide temperature range from -40 °C to +100 °C. In addition to the standard versions, customer-specific pin configurations or variants can be created on request.

Technical Data / Approvals
– Rated voltage: 500 VAC, 760 VAC
– Rated currents: 10 to 40 A at 40°C
– Rated inductance: 0.75 to 6.50 mH
– Other pin outs available on request

Application
– Frequency converters for photovoltaic or energy storage
– Charge stations for electric vehicles
– UPS-systems
– Switching power supplies
