| Description | ABB auxiliary contact accessory designed to provide electrical status feedback from compatible Emax 2 devices to external indication, monitoring or control circuits. |
This component provides auxiliary status signalling for compatible Emax 2 switching devices. Its contacts can be incorporated into control, indication and monitoring circuits to communicate the operating state of the main device.
It is designed for Emax 2 devices in frame sizes E2.2 through E6.2. The complete switch configuration should be checked before installation to confirm mechanical and electrical compatibility.
The 4Q designation identifies an auxiliary contact arrangement with four contacts for signalling the position or operating state of the associated switching device.
Yes. The 24 V designation indicates that 1SDA073754R1 is configured for use in low-voltage auxiliary signalling and control applications.
Yes. The auxiliary contacts can transmit device status to remote indicators, control panels, interlocking circuits or a central monitoring system, subject to the electrical design of the installation.
Typical applications include industrial switchboards, power distribution assemblies, automation panels and DC combiner systems used in battery energy storage installations.
No. It is an auxiliary signalling accessory rather than a main current-switching device. The associated Emax 2 unit performs the principal switching function.
Yes. Its auxiliary contact outputs may be used within appropriately designed electrical interlocking and control circuits to indicate or respond to the state of the associated device.
Yes. ABB documentation lists this accessory as an optional component in a DC combiner configuration for utility-scale battery energy storage systems, alongside compatible Emax 2 equipment.
Confirm the Emax 2 frame size, the required number and type of auxiliary contacts, the 24 V control-circuit requirements, available mounting provisions and the wiring arrangement specified for the assembly.
No. It is intended to operate as part of a compatible Emax 2 assembly and requires the corresponding switching device and correctly designed auxiliary circuitry.
Installation and wiring should be completed by a suitably qualified electrical professional in accordance with the equipment documentation and applicable local electrical regulations.
