AC motor 6 A | Variable speed control | maintenance switch

These electronic speed controllers regulate the speed of single-phase voltage-controllable motors with a maximum current of 6 A by varying the motor voltage via phase angle control (Triac technology). The series feature automatic power detection (110—240 VAC / 50—60 Hz). The minimum speed is adjusted via an internal trimmer. The output voltage to the motor can be adjusted via the built-in potentiometer in the range between the supplied voltage and the selected minimum output voltage (30 to 60% of the supplied voltage). The series has an unregulated output for connecting a valve, an operation indicator, an actuator, etc. There are two start modes (Kick start and Soft start) selectable via a jumper. The motor can be turned on or off via the integrated on/off switch. The ITR can be used in demanding environments thanks to its IP54 protection against moisture, dirt and dust.

Motor maintenance switch with padlockable OFF-position. It can be used to ensure safe working conditions while performing maintenance tasks and to cut a motor off from the electrical grid. The (combined) maximum load is 3 kW. The forced open contacts fulfil load break requirements up to 690 VAC. This makes them also suitable as motor emergency-OFF switches or as enclosed main switches for individual electrical loads. The switchgear is housed in a moulded enclosure with an IP65 sealing. This switch has 2 poles and one normal open and one normal closed auxiliary contact. Manufacturers code: Kripal UKPN1-2P20A/11
