About this item
New product in manufacturer's box
Model: 3RH1140-1AK60
The auxiliary contactor is an electromechanical device used in electrical control systems to assist in switching and controlling auxiliary circuits in conjunction with main contactors. It is not designed to carry high currents like main contactors but plays important roles in control and signaling circuits.
Contactor relay, 4 NO 110 V AC 50 Hz / 120 V 60 Hz Screw terminal size S00
Three-pole: Has three main contacts that control the current to the motor, allowing the switching of three-phase loads.
Coil voltage: 110V AC at 50Hz or 120V AC at 60Hz, compatible with various power grids.
Rated current: 10A, supporting loads up to 10 amperes.
Insulation voltage: 690V, ensuring safety and protection against voltage peaks.
40E Series: Compact and lightweight, ideal for optimizing space in control panels.
Screw terminals: Provide firm and reliable connections.
Certifications: Meets international quality and safety standards.
Control of electric motors in industrial machinery, such as pumps, fans, and conveyors.
Switching of three-phase loads in power circuits.
Interlocking of devices in automated control systems.
Actuation of annunciators and other auxiliary devices.
High reliability: Ensures safe and uninterrupted operation, even in demanding environments.
Long lifespan: Designed to withstand millions of switching cycles, minimizing maintenance costs.
Easy installation: Screw terminals facilitate the connection and removal of the contactor.
Versatility: Suitable for various applications in motor control and power circuits.
Safety: Meets the most rigorous safety standards, protecting against electric shocks and short circuits.
Compact: Takes up little space in control panels, optimizing space utilization.
