NFZ auxiliary contactors are used to switch auxiliary and control circuits. They have an electronic coil interface that can implement a very wide control voltage. Only four coils cover control voltages between 24...250 V 50/60 Hz or 12...250 V DC. The large control voltage range of the coils means that large control voltage fluctuations can be handled. NFZ auxiliary contactors enable direct control via 24V DC 250mA PLC outputs and require a very low holding power of just 1.7W. NFZ auxiliary contactors can withstand short voltage dips and voltage drops (according to SEMI F47-0706) between 24...250 V 50/60 Hz. They have built-in overvoltage protection and do not require additional suppressors - Poles: 4-pole auxiliary contactors (mechanically linked auxiliary contacts according to Annex L of IEC 60947-5-1 and including the 'positive guide' symbol on the side of the auxiliary contactor) - Control circuit: AC or DC operated - Accessories: a wide range of accessories is available.
