Moeller Rotary Switch
Customised circuits can be implemented to standard configurations. The Moeller switch range comes with numerous accessories to complements the range to be specified towards end user applications. Moeller Rotary Switches T and switch-disconnectors P are ATEX approved and enable use in dust explosion hazardous areas.
Areas of use include:
- Metal grinding plants
- Wood processing & wood process areas
- Cement factories
- The aluminium industry & foodstuff industry
- Grain storage & processing facilities
- Pharmaceutical industries
Powerful, rugged and compact Moeller switches offer a quick assembly and delivery program.
Moeller T type switches are suitable for motor disconnect and control circuit applications.
Options for P Disconnect rated from 20A to 100A include side mount auxiliary contact and late make / early-break for electronic starter applications.
Moeller Mini Rotary Switch TM
The Moeller TM Mini Rotary Switch Stands out well particularly due to its small size and simple handling and mounting features (There are several construction types available). The rating of the Moeller TM to AC23 is 3kW at 400/415V, 50-60Hz. The rated uninterrupted current / is 10A.
Common Uses of the Moeller TM:
The mini rotary switch TM is mainly used as an On-Off switch, changeover contact, step switch, control switch, coding switch and control circuit isolator.
Moeller Rotary Switch T
The Moeller Rotary Switch T represents a flexible, compact and robust modular system. Moeller T rotary switches contain two frame sizes.
The ratings of the T switch range from 6.5kW to 132kW with AC23A at 400/415V, 50-60Hz. The rated uninterrupted current / is between 20A and 315A. Moeller Rotary Switches are an economic choice for simple logic function and manual switching required in numerous industrial applications.
Moeller provides an array of standard and custom switches to precisely match functional requirements. Various handle types, shrouds, shaft extension, neutral terminals and keyed operator accessories are available.
The Moeller Rotary Switch T is ideal for a varied range of applications. Red handles and yellow faceplates options are available enabling usage for approved emergency stop switches in all products lines and frame sizes.
Moeller T rotary switches for auxiliary circuits simplify command functions at central locations. The modular system is particularly flexible and enables a wide range of different combinations and types.
Coding, step, series and manual/automatic switches are common applications for auxiliary-circuit control switches. T0 rotary switches and TM mini rotary switches are particularly suitable for this purpose, with space-saving installation. With up to 22 contacts and 12 switch positions, the T0 handles a wide range of switching tasks.
Application uses for T Rotary Switches include:
- Star-delta motor starting circuits with or without reversing and with or without a contactor interlock.
- Motor speed variation (tapped windings) for two, three or four speeds, with or without reversing.
- Switching a load between two power systems, or connecting one power system to two loads using the same switch.
- Three-phase motor starting on a single-phase power system with a capacitor.
- Stepped switching for any required number of loads, with or without a zero position.
- Ammeter switching for measurement directly or via current transformers.
Moeller Switch-Disconnector P (Reliable Switching up to 100 A)
The Moeller Switch Disconnector P1 up to 32A, P3 up to 100A, P5 up to 315A is compact and robust. The manual operator acts directly on the contacts. The contacts are positively opened on de-energisation. Moeller P Switch-disconnectors can be used as On-Off switches as well as maintenance, manual override or safety switches with and without emergency stop functions.
From simple ON-OFF disconnects, to reversing wye-delta motor control, Moeller offers an array of standard and custom switches to precisely match functional requirements.
Moeller P rotary switches contain two frame sizes which can handle loads to 100A or 75HP. Moeller P motor disconnect line has a robust amp and horsepower capacity with optional built in auxiliary contacts in standard selection.
Red handles and yellow faceplate options are available for approved emergency stop switches. Multiple mounting options are available to provide application flexibility along with various handle types, shrouds, shaft extension, neutral terminals and keyed operator accessories.
Moeller P Switch Application Use:
Moeller P switch disconnectors are particularly suitable as safe maintenance and repair switches or as enclosed main switches for individual electrical loads. Multiple padlocks can be connected in the OFF position, providing a vital safety function: the no-voltage state is visible and switch ON is impossible.
Moeller P Switch disconnectors provide reliable operation with heating and lighting systems, motors etc. Disconnectors are suited for direct switching of motor. Selection of the switch is performed to suit the rate uninterrupted current or the motor rating in accordance with utilization category AC-23A. In application uses where frequent switching of ON and OFF operations are necessary, the high switching capacity guarantees reliability.
Auxiliary Current Control Switch
Rotary switches T and TM for auxiliary current circuits simplify command functions and central points. Saving time and introduces clarity to the production process. Coding switches, step switches, sequence and manual/automatic switches are frequent applications for the auxiliary current control switch.
Rotary switches are suitable for switching electronic circuits conform to IEC/EN 61131-2 VDE0411 part 500. The Moeller T0 can master as whole range of switching applications with up to 22 contacts and 12 switch positions.
Rotary Switches T0 with their large surfaces can also be operated when the operator is wearing gloves. The Moeller TM range is ideal for small size applications and fits nicely with command and signalling range RMQ. All contacts feature double breaking contacts.
Safety Switch with Load Shedding and Signalling
Moeller Safety Switches P and T are functionally designed as maintenance and manual override switches. Safe isolation of a load from main is a primary function. Moeller Switches can be loaded with rated uninterrupted current / due to the load shedding circuit. The switch switches without a load and additional signalling contacts can be used for indicating the switch position. The respective processing and use in the application program of the system enhances safety.
