Schurter’s TA35 series introduces a new generation of Circuit Breakers for Equip-ment. The breakers are available in 1-, 2- or 3-pole arrangements. The rocker-actuating switch can be supplied either with or without illumination, in several colors and with various legends or customer specific symbols. New is the version in fluorescent popular blue. The breakers have been de-signed for efficient snap-in mounting, fitting panel thicknesses ranging from 1 to 4 mm. Connections are made with 6.3 x 0.8 mm quick connect terminals. The TA35 pro-vides both the function of a switch as well as thermal overload protection. It has finely graduated rated currents of 0.05 A to 20 A for the 1- and 2-pole types, or 0.05 A to 12 A for 3-pole versions. An optional protective cover gives a protection class of IP 65, making the unit suitable for applica-tions exposed to dust or splashing water.
Typical applications are laboratory equip-ment for chemical and medical applica-tions, wood and masonry processing ma-chines, construction site equipment, power generators, cleaning equipment, food-processing equipment and appliances. The circuit breaker is approved according to IEC 60934, UL 1077 and CSA C22.2 235 and carries VDE and cURus.
As well as factory automation and industrial controls, typical environments for these connectors include semiconductor and LCD manufacturing machinery; medical equipment, packaging systems, conveyor systems, elevators and lift systems; flow meters; motion test and measurement systems; traffic light and control systems; base press control electronics; food and packaging industries; automotive and metal industries; solar and alternative energy; and sensors. A key feature of the range is the use of 3M insulation displacement technology (IDC), which provides higher connection reliability, while at the same time eliminating cable stripping and tinning, as well as the need for repetitive screw-type wire terminations.
The connectors also have an integrated guiding and alignment feature built into the cover, which provides reliable positioning of the individual wires. Semi-transparent covers allow for visual inspection to check correct wire positioning prior to termination. Polarizing tabs help provide proper mating while latching features help provide a secure connection, even under severe conditions such as mechanical stress and vibration in industrial environments. The Connectors are available in a 2mm pitch that use colour coding (red, yellow, orange, green, blue and grey) to ensure proper wire usage, wire alignment and retention of the cover.
The 3M Mini-Clamp II Connectors are available in 3- and 4-pin wiremount configurations, in two socket styles and a plug version. They are also available in boardmount socket configurations: a 3- and 4-pin single row socket connectors; and a 6-pin (2 x 3 pins), an 8-pin (2 x 4 pins), a 12-pin (4 x 3 pins) and a 16-pin (4 x 4 pins) multi-row socket connector. Dust caps are available for more harsh and dusty environments. The new connectors join the existing Link wiremount 381 series and boardmount socket series 382, both of which are available in 4-pin configuration and meet the industry-wide CC-Link standard.
