ABB EH04-20N Series Auxiliary Contact, 6A Operational Current, 500V Rated Insulation Voltage - 1SAE901901R1020


This auxiliary contact is a side-mounted switching accessory designed to extend the signalling and control capabilities of installation contactors in electrical panels. It provides additional changeover functionality for AC auxiliary circuits at supply frequencies used in industrial automation, enabling clear state indication and auxiliary switching without modifying the main contactor.

Features & Benefits


• 2NO configuration adds two independent normally open contacts for signalling
• Rated insulation voltage500V supports higher-voltage control circuits
• Conventional thermal current6A permits modest auxiliary loads
• Screw Terminal connections enable secure wiring with stranded conductors
• DPST arrangement supplies two-pole switching for dual-circuit control
• Operational range -25°C to55°C suits typical plant ambient conditions

**Applications**


• Suitable for expanding contactor control circuits in factory automation
• Used with installation contactors to provide remote status signalling
• Ideal for integration into control panels requiring two-pole auxiliary switching
• Can be used for motor starter interlocks and control logic feedback

What mounting method is required for installation?


It fits to the side of compatible installation contactors and secures without tools during assembly.

Which conductor sizes are supported on the terminals?


Top and bottom terminals accept single and dual conductors

common capacities include 1x1.5mm², 1x2.5–4mm² and 2x1.5mm² for typical panel wiring.

How does the device behave under transient overvoltage?


The unit is specified with a rated impulse withstand of4kV, providing resilience against standard transient events in control circuits.

Are there torque recommendations for Terminal fastening?


Tightening torque values are provided for reliable electrical contact and vary by Terminal type, with auxiliary circuit torques specified for correct clamping.
