£122.38
The ABB EF19-1.0 Electronic Overload Relay (1SAX121001R1102) is a compact self-powered electronic motor protection relay designed to provide precise overload and phase failure protection for three-phase motors. As part of the advanced ABB EF19 electronic overload relay series, it combines the accuracy of electronic protection with the simplicity of a conventional thermal overload relay, making it ideal for industrial motor starter applications.
The EF19-1.0 requires no external control power supply, simplifying installation and reducing wiring requirements. It offers selectable Trip Class 10E, 20E or 30E, automatic or manual reset, integrated temperature compensation, phase loss sensitivity and built-in STOP and TEST functions for dependable motor protection in demanding industrial environments.
With an adjustable current setting range of 0.30 to 1.00 A, the EF19-1.0 is ideal for protecting small three-phase motors used in conveyors, pumps, fans, packaging machinery and OEM equipment. It mounts directly onto compatible ABB AF09, AF12, AF16 and AF26 contactors for compact motor starter assemblies.
Electronic overload relays continuously monitor motor current with greater precision than traditional thermal relays, delivering accurate overload protection over a wide ambient temperature range while detecting phase loss to help prevent motor damage and costly downtime.
The ABB EF19 series combines the simplicity of thermal overload relays with advanced electronic protection, making it an excellent choice for machine builders, OEMs and industrial maintenance engineers seeking reliable motor protection.
