Equipment for use in dust explosion hazardous areas

Moeller now offers T rotary switches (from 20 A to 100 A) and P switch-disconnectors (from 25 A to 100 A) conform to the ATEX directive 94/9 EC from 01.07.2003.

The devices are marked with equipment designation EX II3D IP5X T90°C (Dust-EX) and are Ex-zone 22 approved for use in dust explosion hazardous areas.

Safety in dust explosion hazardous areas

Processes require power. You now have these ATEX switches from Moeller to satisfy the demands of your customers with regard to main switch, maintenance switch and manual override switch requirements in their machines and systems.

The installation and application notes for use in machines and systems must be observed

The fields of applications for ATEX switches include all manufacturing fields where deposits of dust are an issue. These include, for example: Mills, facilities where metals are ground as well as the wood processing, cement or aluminum industries.

Control circuit devices from the RMQ-Titan® range can be combined with the LS-Titan® switches – an innovation: Pushbuttons, mushroom actuators, selector switches, keyswitch actuators and emergency-stop actuators can be snapped onto every position switch as operating heads.

The entire front and rear sides of the unit have at least IP 66 enhanced degree of protection. This solution opens a whole new range of applications. With the combination of position switch and control circuit device, there results for the first time a control device which possesses a defined snap-action operating behaviour. Operation is initiated by the control circuit device, the abrupt switch change acts on the contact system of the position switch.

The complete unit has very compact external dimensions ensuring space availability for it in any machine or system.

The operating heads can be fitted in all four directions (4 x 90°) and quickly and easily installed with a bayonet catch.

The particular mounting advantage: After the position switch has been fitted, the operating head can be correctly adjusted to suit the required direction of motion without problems

The fuly insulated plastic housing conforms to protection class II. Thus, they are simple to install and do not require a protective earth terminal. This saves wiring time and precious tooling time.

Die-cast metal enclosures (protection class I) are available for applications in harsh operation environments. Enclosures of this nature are particularly suitable for welding systems, as they are resistant to airborne sparks.

All basic units have standardized sizes and are conform to the EN 50047 standard. The operating heads can be rotated through 4 x 90 degrees and can be combined with every basic unit. Equipped with double-break contacts, they are also suitable for use in the configuration of redundant safety circuits.

The termination's are equipped with maintenance-free and vibration protected cage-clamp termination's. The largest terminal capacity allows the connection of solid and flexible connection cables with conductor cross-sections from 0.08 to 2.5 mm².

The innovative LSE position switches represent a market premiere, as it is the first time that a single device for all applications has been launched on the market, and is also for safety-relevant tasks and applications. The use of just a single type offers a wide-range of advantages: There is an enormous reduction in the complexity and expense in areas such as logistics, purchase order processing, stockkeeping and administration associated with bills of materials

Further convincing advantages: Divergent positions for the attachment bores or tolerances of brackets and flaps have no influence on the operating point of the position switch. After mounting the device, the operating point is “learned” eliminating any time-consuming fine adjustment tasks. This saves precious time and avoids high tooling costs. Furthermore, every electrician and mechanic around the globe is in a position to effortlessly adjust the devices. The devices plainly signal all actions and include optical indication

ATEX =Atmospheres Explosibles = explosive atmospheres

Moeller now offers the following in conformity with the manufacturers guidelines: ATEX guideline 94/9 EC (mandatory from 06/2003) devices from the RMQ Tiatn range and the FAK range.

The switches are approved for device group II, with area of application "all except mining" as well as for category 3. The approval has the test number BVS 06 ATEX E023U, BVS 06 ATEX E024X.

Big and rugged

FAK foot and palm switches with their large operating surfaces are tamper-proof to ISO 13 850/EN 418. They can be actuated with the flat of the hand, the closed fist, wearing  gloves and with the elbow or foot, thus allowing the operator to react quickly. The high degree of shock resistance and protection to IP 69 K make the FAK the ideal device for rugged applications

For example, FAK foot and palm switches are fitted on the outside of refuse collection vehicles. They can even be cleaned with high-pressure steam jets

The Emergency-Stop button in the RMQ 16 range offers a number of significant features - tamper-proof, degree of protection IP 65, and the availability of an illuminated version. An integral multiple LED is either permanently lit or lights up when actuated according to the circuit design.

Self-Seeking Power Supply

The DSE160 is a self-seeking power supply designed to work with DSE300 Series Auto Transfer
Switch Controllers.

The module can be supplied form mains (utility), generator or battery and provides a power supply
output for ATS controllers.

The module will provide DC power to the modules and when the mains/utility power is lost, will
automatically switch to providing power from either the generator or battery.

10 Amp 24 V Battery Charger

The DSE 10 Amp Switch Mode Battery Chargers are designed to be permanently connected to a battery, keeping it charged to maximum capacity. The chargers can be mounted to the chassis or panel using the fixing points or optional DIN rail clips.

The charger’s stylish design includes two LED indicators on the front to show when the charger is connected to the mains/utility supply and to indicate when a fault condition occurs.
