Bulletin 194L Control and Load Switches

Bulletin 194L IEC Control and Load Switches

• 12, 16, 20, 25, 32, and 40 A inductive load-rated switch
  
• IP66 water spray and dustproof handles
  
• IP20 finger-safe terminals
  
• Switches available for OFF-ON, changeover, star-delta (wye-delta),
  reversing, ammeter, voltmeter and step switch configurations
  
• 1-…6-pole versions
  
• Front/door- or base/ DIN Rail-mounting configurations
  
• Thermoplastic enclosures IP66
  
• Suitable as motor disconnect (UL 508)
  

Bulletin 194L control and load switches are flexible, adaptable, time- and space-saving devices. Switches are available as front/door- or Base/DIN Rail mounting versions. Uniformly styled handles, featuring marked legend plates, are available in Selector-Knob, Disk-Style, Rectangular-Style and Key-Operated versions. Selector-Knob versions are available in three sizes. Most handles are available in grey/black or red/yellow and have padlockable versions.

A new thermoplastic enclosure features constructions of impact-resistant ABS or corrosion resistant NORYL materials. Both shallow and deep versions include 35 mm DIN Rail, grounding and neutral terminals, and captive cover screws. Enclosures may be ordered with or without cover openings for handle mounting. Enclosures are rated for use in IP66 (UL Type 1, 3, 3R, 12) environments.

Product Overview



OFF-ON Switch

Two-position switch used to connect or disconnect a variety of inductive loads including: solenoids, handles, valves, magnetic starters and relays.



Ammeter Switch

Multi-position switch used to connect one or more phases of an electrical supply to an ammeter, so that the current in each phase can be displayed on one ammeter.



Changeover Switch

Two-position switch used in control applications to change between alternate power supplies. This device can typically be used to manually switch power supplies from a primary source to a stand-by/emergency supply in the event of a power outage.



Voltmeter Switch

Multi-position switch used to connect two lines of the electrical supply system to a voltmeter so that the voltage between the lines (phase-to-phase or phase-to-neutral) can be displayed on one voltmeter.



Star-Delta (Wye-Delta) Switch

Three-position (Off-Wye-Delta) switch used to manually control reduced-voltage motor starting. Operating the switch manually changes the wiring configuration of the motor from a star configuration to delta configuration after the controller operator has determined that the motor is up to operating speed.



Step Switch

Multi-position switch used to connect a variety of loads to an electrical supply in a pre-determined logical sequence. A typical application would be temperature control of a heating oven or furnace.



Reversing Switch

Three-phase, three-position (Forward-Off-Reverse) switch used to manually control a motor’s direction of rotation. Operating the switch changes the wiring configuration of the motor to operate in the forward or reverse direction.
