Company	ABB Low Voltage & Systems
Description	NF - Contactor relays - AC or DC Operated
Bill of material	ABB - 1SBH136005R2044 + NFZ44EK-20 12-20VDC Contactor Relay
Product ID	1SBH136005R2044
Extended Product Type	NFZ44EK-20
Invoice Description	NFZ44EK-20 12-20VDC Contactor Relay
Description	Push-in Spring Terminals 8 Poles NF Contactor Relay - Top Mounted Coil Terminal
Long Description	NFZ..K contactor relays are used for switching auxiliary and control circuits. NFZ contactor relays include an electronic coil interface accepting a wide control voltage Uc min. ... Uc max. Only four coils cover control voltages between 24...250 V 50/60 Hz or 12...250 V DC. NF contactor relays can manage large control voltage variations. One coil can be used for different control voltages used worldwide without any coil change NFZ contactor relays allow direct control by PLC-output ≥ 24 V DC 500 mA and obtain a reduced holding coil consumption. NFZ contactor relays withstand short voltage dips and voltage sags (SEMI F47-0706 compliance) between 24...250 V 50/60 Hz NFZ contactor relays have built-in surge protection and do not require additional surge suppressors. Only NFZ..-20 contactor relays need to respect the polarity on the coil terminals (A1+ and A2-). NFZ..K include Push-in Spring terminals. Only one push is all you need for extremely fast wiring: faster than ever installation, easier than ever wiring, reliable as ever connections. Poles: 8-pole contactor relays with a non-removable front-mounted auxiliary contact block (mechanically-linked auxiliary contacts compliant with Annex L of IEC 60947-5-1 and including the "Mechanically Linked" symbol on the contactor relay side).
