Applications:
The switches must be selected according to the following performance specifications:
1) According to motor switching capacity, when the switch is fitted in such a way that the operator may use it for operational ON and OFF switching.
2) The rating data always applies to 3 poles. When the motor rating is divided between 6 poles, such as for star-delta switching, a 6 pole switch can be used to control 1.73 times
the rated power.
3) If the switch has a load-shedding Contact (LA), you can select the appropriate switch according to the uninterrupted current. The load-shedding contact is an auxiliary contact, which s closed in the ON position and opens early when witching off, so that a contactor located in the circuit takes over the switching duty and the maintenance/safety switch
operates at zero load. When switching on, the load-shedding contact closes later than or at the same time as the main contacts. With UKP and UKT switches this is the N/O auxiliary contact.
4)The "ON" position can be locked with a padlock (by altering the handle).
This is not permissible for switches with a red/yellow handle.
Features:
• Safety switches are always housed in insulated enclosures and have an inscription saying "Safety Switch" on a bright orange label.
• Switches to be used for emergency stop switching have a red handle and yellow locking collar in accordance with STOP category O (as per IEC/EN 60204/VDE 0113).
• If the switch is not approved for emergency stop switching, both parts will be black ("SW" part no. suffix).
• The cover and handle are interlocked by fitting a padlock.
Installation:
A. front mounting: four pole mounting; single hole mounting;
B. ase mounting: Snap-on mounting (DIN rail 35mm)
C. Enclosed Switches: PC enclosure; stainless steel enclosure
Optional:
a. Netural contacts
b. 1NO+1NC module
c. Color of handle and surroundings
With a broad range of mounting and operator options, Purple Horn Electric can provide economical, versatile and reliable solutions!
