Schurter is merging its expertise in the area of robust metal switches with reliable circuit breakers into a unique product: the T12-MSM is the first circuit breaker on the market that is extremely attractive from a visual standpoint. With its extraordinary actuating appeal, the T12-MSM need not be used as just another switch to be hidden on the rear of the equipment; rather it can be stylishly displayed on the front.

Schurter combines its circuit breakers with thermal operation (T12) and thermal-magnetic operation (TM12) with its MSM series metal switches. The T12-MSM, creates a market innovation that marries overcurrent protection with an attractive pushbutton design. The MSM switches are characterized by their visual appeal and operating characteristics. Both the housing and the actuator are fabricated from high-quality stainless steel, and there are a variety of design options including size, color, lighting and inscription.

The T12 and TM12 are reliable circuit breakers with positive trip-free operation. The contacts open even if the reset button is manually held in the closed position. They reliably protect equipment with rated currents from 50 mA to 16 A. The optional magnetic release, protects against increased risk of short circuits.

The combination of the T12 circuit breaker and the MSM switch now unites all these features in product that is also extremely robust. With a vandal-proof design, IP 64 tightness protection and IK 07 impact resistance, the T12-MSM is also suited for outdoor applications and use in harsh environments. Additionally, the look and feel is novel for a circuit breaker and stands out among other circuit breakers as a true designer piece, suitable for mounting on the front side of the equipment, where an appealing design is paramount.

Schurter expands its successful range of FMBC NEO 3-phase filters with a low leakage current series for applications where no high leakage currents are allowed. The new FMBC LL series of filters is designed for rated currents between 7 and 180 A. It is ideal for leakage current-critical industrial applications such as drive technology.

Today's electrical industrial installations are increasingly being fitted with residual current devices (RCD) to ensure efficient personal protection. This is also a requirement in certain countries for 3-phase systems, for example plug-in systems up to 32 A. The RCD limits the current to earth to a maximum of 30 mA. This poses a particular problem in drive technology since the frequency inverters that control the engine generate considerable leakage current.
Long motor cables further aggravate the problem since they increase the capacity to earth and hence the currents to earth too. The new series of FMBC LL filters helps reduce the leakage currents and permits compliance with common EMC standards as an efficient input filter.

The compact FMBC LL 3-phase filters have been designed for currents from 7 A to 180 A at an ambient temperature of 50 °C. They have UL approvals for ambient temperatures of +50 °C as well as +40 °C at a higher rated current. The FMBC LL is approved for rated voltages of 520 VAC. This means that they can be used in high-power systems, such as machines used in an industrial environment. Despite their high output performance, they are still compact and
lightweight in design.

The standard FMBC LL is fitted with a screw connection. Other types of connections including wires or copper bars are possible on request as well as customised modifications to the circuit or housing. SCHURTER also offers its own EMC measuring service for an optimum adjustment to the inverter. Therefore the most efficient filter solution for the system can be developed.

Technical Features:
- Rated voltage: 520 VAC
- Rated current: 7 A to 180 A
- Leakage current 7 – 55 A: < 5 mA, leakage current 75 – 180 A: < 20 mA
- Screw connections
- cURus approval: E72928

The new MSM LA CS ON/OFF stainless steel pushbutton switch from SCHURTER is equipped with an actuator made of durable ceramic. The same ceramic is already being used to manufacture the previ-ously introduced MSM CS momentary action switches. The material resists scratches and abrasive chemicals as well as impact; it can also be labeled with highly durable legends.

The non-illuminated versions of the MSM LA CS and MSM CS switches are offered with a white actuator surface. Standard or customer-specific black legends are applied directly into the ceramic material. Due to the base material and the labeling process, the inscription is scratch-proof and stands up to common cleaning agents. The illuminated design provides a uniform glow across the entire surface in the desired illumination color (red, green, blue, white, orange).

The MSM LA CS pushbutton switch is available with mounting diameters of 19 and 22 mm. It is suited for use in a temperature range of -20 °C to +85 °C. Equipped with blade terminals, the MSM LA CS can be wired up very quickly: the pre-assembled cable set is plugged into the quick-connect terminals of the microswitch, which is then snapped into the switch housing.

The sturdy stainless steel housing and the actuator made of scratch-proof ceramic make the MSM LA CS latching action and MSM CS momentary action switches especially well suited for use in equipment operating in harsh environments, or applications that require protection against vandalism. These in-clude, for instance, vending machines, ticket machines, equipment in restaurant operations, public facili-ties, sanitary facilities as well as applications in hypoallergenic environments such as the medical sector.

Technical Information / Approvals

The PSE EX 16 family has been extended to include the PSE EX 19 and PSE EX 22 mounting diameter. Furthermore, the certification of the PSE EX was enhanced and expanded. The PSE EX family is approved for use in potentially explosive atmospheres containing air and gases. Further application areas also include industrial sectors such as mills, where solids are found in smallest form as dust, which may be prone to self-ignition.

Flammable substances such as gases, vapors or mist which are released into the environment, e.g. while in production, during transportation or storage, may ignite and pose serious consequences for persons and property. The same is true for dust which may develop in conjunction with air to an explosive atmosphere. To ensure security in these areas, the Device Directives 94/9/EC was developed for products and protection systems. The purpose of the guidelines is the protection of personnel and devices which are working in such hazardous areas. This is done by eliminating all possible sources of fire and ignitions in the products and systems used in these areas.

The PSE EX family is certified according to ATEX and IECEx regulations. The area of application is consistent with that of the device group II (other areas than mining). It comprises systems with a potentially explosive atmosphere consisting of a mixture of air and gases, vapors or mists or in industrial areas where dust-air blends infuse the atmosphere and the danger of a dust explosion can arise.

The approval marking is Ex II 2 GD (according ATEX regulations), Ex ib IIC T6 ... T5 Gb and Ex ib IIIC T85 ° C ... T100 ° C Db (according IEC regulations) for gases and dust. The temperature class was extended from T4 to T5 and T6. Therefore the permissible power dissipation of the PSE EX was limited accordingly so that the piezo switch is intrinsically safe according to EN60079-11. In addition, the flammability group was increased from IIB to IC, respectively IIIC (gas, dust). This extension will allow the use of the PSE EX in atmosphere with further type of gases, combustible dust, ignitable fibers and flyings.

Typical applications include oil and gas exploration rigs, petrochemical facilities, environments of transportation and storage of combustible materials, paint mixing devices, painting devices, grain mills, wood processing industry, chemical plants etc.

The PSE EX standard models are available with mounting diameters of 16, 19 and 22 mm with pin connectors and housing colors in red, green or natural aluminum. On request other colors, housing diameters and connection versions are obtainable. The switches for hazardous use have a label with the particulars of the certification and an identification number. Installation instructions are included in the packaging according to the ATEX directives.

Technical data / Approvals:
- PSE EX 24V, 40 mA, PT6 = 0.7 W, PT5 = 0.96 W
- ATEX II 2 G D
- IEC Ex ib IIC T6…T5 Gb
