Siemens 3th4280-0ak6 Contactor Relay 8 Pole 110/120 Vac

Product Description

The SIEMENS 3th4280-0ak6 is a SIRIUS contactor relay designed for industrial control panel and automation applications. It features an 8-pole configuration with 8 normally open (NO) contacts, rated at 10/2 amps at 230/690 volts AC and 10/0.6 amps at 48/440 volts DC. The coil operates at 110/120 volts AC at 50/60 Hz, making it suitable for standard North American and international control circuits. With an IP20 protection rating, a snap-on mounting system, and screw terminal connections, this relay is built for panel-mount installations where reliable, multi-pole switching is required. Licensed electricians and industrial controls technicians are the primary installers.

This contactor relay is suited for use in industrial control cabinets, machine automation panels, and building management systems where multiple auxiliary switching channels are needed in a compact form factor. The 8 Form A contact arrangement supports independent load switching across multiple circuits simultaneously. Its operating temperature range of -25 to 55 degrees C covers demanding industrial environments. The snap-on DIN rail mount streamlines installation in standard enclosures.

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial control systems requiring an 8-pole auxiliary contactor relay with a 110/120 volt AC coil and snap-on DIN rail mounting.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the control panel before installing or replacing this relay. Verify coil voltage matches the available control circuit voltage before energizing. Screw terminal connections should be torqued per the panel manufacturer or enclosure wiring standards using appropriate hand tools.
