Auxiliary contactor 250-500V AC/DC - Auxiliary relay 250...500VAC NF31E – ABB – 1SBH137001R1431 – 3471523100244: Auxiliary contactor 250-500V AC/DC NF31E rated control supply voltage Us at AC 50 Hz 250 ... 500V, rated control supply voltage Us at AC 60 Hz 250 ... 500V, rated control supply voltage Us at DC 250 ... 500V, type of voltage for actuation AC/DC, rated operational current Ie, 400 V 3A, connection type auxiliary circuit screw connection, mounting type DIN rail/screw, number of auxiliary contacts as NC contact 1, number of auxiliary contacts as NO contact 3, number of auxiliary contacts as NC contact, delayed switching 0, number of auxiliary contacts as NO contact, leading 0, Number of auxiliary contacts as changeover contacts 0, The 4-pole NF auxiliary contactors are used to switch auxiliary and control circuits (positively driven contacts available). They feature an electronic coil interface that allows a wide control voltage range and can handle large control voltage swings. LF contactor relays have built-in overvoltage protection and do not require any additional quenching elements.
