Product catalog summary
Technical Specifications:
  • Input Voltage: 85-250 Vac 50/60 Hz
  • Delay Time: Adjustable from 1 to 5 seconds
  • Dimensions: 40 x 79 mm, depth 90 mm
  • Housing Material: Polyamide UL 94V2
  • Protection Fuses: Two 2.5 Amps delayed fuses
  • Operating Temperature: -20°C to +60°C
Device Overview:

The PT73 is designed to provide additional protection for units, particularly in systems with significant surges and fluctuations in the 230 Vac power supply. It effectively reduces peak voltage generated when closing the MV switch, thanks to its turn-on delay feature. Installation is straightforward via the DIN EN50022 rail, and a red LED indicates fuse intervention.

Installation and Usage Recommendations:

The device is recommended for use in environments with high voltage surges or fluctuations. It is easily installed within an electrical panel using the DIN EN50022 rail system. The red LED serves as an indicator for potential fuse activation.

PT73-1

Il PT73 e un dispositivo in grado di fornire una protezione supplementare alle nostre centraline. Il suo utilizzo e consigliabile su impianti dove sono presenti elevate sovratensioni o oscillazioni della rete elettrica 230 Vca. Inoltre risulta molto efficace nel tagliare il picco di tensione che si genera alla chiusura dell'interruttore MT, grazie all'azione di un ritardatore di accensione. E facilmente installabile all'interno del quadro elettrico tramite l'attacco a guida DIN EN50022. Un led rosso indica l'eventuale intervento dei fusibili di protezione. SpecificheTecniche • Tensione di Ingresso: 85-250 Vca 50/60 Hz • Tempo di ritardo: regolabile da 1 a 5 sec • Fusibili di protezione (x2): 2,5 Amps (rit.) The PT73 is a device that can provide additional protection to our units. Its use is recommended on systems where there are large surges and fluctuations in 230 Vac power supply. Moreover, it is very effective in cutting the peak voltage that is generated when you closed the MV switch, thanks to a turn-on delay.
