Product Description
ABB 1SAE901901R1020 Auxiliary Contact is part of the EH04-20N series, designed to offer enhanced signaling and control capabilities for installation contactors in industrial automation and electrical panel systems. This side-mounted accessory provides two normally open contacts in a DPST (double pole, single throw) configuration, enabling dual-circuit auxiliary switching with a rated operational current of 6A and insulation voltage of 500V.
The screw terminal connections allow secure wiring with single or dual stranded conductors, commonly supporting conductor sizes such as 1x1.5mm², 1x2.5 - 4mm², and 2x1.5mm². The device supports operation in ambient temperatures ranging from -25°C up to 55°C, suitable for typical plant environments. Additionally, the auxiliary contact exhibits a rated impulse withstand of 4kV, granting durability against transient overvoltage events common in control circuits.
This auxiliary contact is especially suited for expanding the control circuits of factory installation contactors, providing remote status signaling and additional switching functionality without modifying existing main contactors. Typical applications include motor starter interlocks, control logic feedback, and integration into control panels requiring reliable two-pole auxiliary operation.
Side mounting for easy attachment without tools to compatible contactors. Two normally open contacts enable dual independent signaling paths. Screw terminals provide durable and secure electrical connections. Rated for 6A operational current and 500V insulation voltage.
Temperature operation range from -25°C to 55°C ensures robustness in varied industrial climates. High impulse withstand rating (4kV) for transient voltage protection. Manufactured in Bulgaria, meeting quality and reliability standards.
For industrial, automation, and electrical panel applications, this ABB auxiliary contact enhances the operational flexibility and safety of contactor systems. Browsing other Auxiliary Contacts and control gear in the Electronics & Electricals category on EnvMart can further assist in completing your control panel solutions.
