Product Description

Siemens 3KX3582-1YC Auxiliary Switch – 1NO + 1NC for Superswitch 3KL84/3KA84

The Siemens 3KX3582-1YC is an Auxiliary Switch with 1NO + 1NC contacts for the Siemens Superswitch 3KL8/3KA8 switch-disconnector range. Siemens accessory documentation identifies this exact article for the 3KL84 and 3KA84 switch-disconnector families.

Unlike several other Superswitch SKUs in this series, the supplied product title is correctly identifying this article as an auxiliary switch. The Siemens accessory table specifically lists 3KX3582-1YC under Auxiliary Switch (1NO+1NC).

For SB Smart, this product is positioned as a Siemens industrial electrical accessory for switch-position indication, auxiliary signaling, control circuits and replacement requirements.

Siemens 3KX3582-1YC Auxiliary Switch

The 3KX3582-1YC is designed to operate as an auxiliary contact device alongside compatible Siemens Superswitch switch-disconnectors.

The auxiliary switch provides additional electrical contacts that change state according to the operating position of the associated switch-disconnector. This allows the main power switching device to provide an auxiliary signal to another circuit.

Siemens' accessory documentation identifies 3KX3582-1YC specifically for the 3KL841/842/843 and 3KA843/844/845/846 configurations.

1NO + 1NC Contact Configuration

The exact 3KX3582-1YC provides:

• 1 Normally Open (NO) contact

• 1 Normally Closed (NC) contact

This combination allows one auxiliary signal to be generated through a normally open circuit and another through a normally closed circuit.

The contacts can be used for compatible:

• Switch-position indication

• Control circuits

• Status signaling

• Interlocking circuits

• Remote indication

• Electrical monitoring

The actual contact behavior depends on the position of the associated Superswitch and the wiring arrangement.

Normally Open Contact

The NO contact is open in its normal condition and closes when the auxiliary mechanism is actuated by the associated switch-disconnector.

It can be used for compatible applications such as:

• “Switch ON” indication

• Auxiliary control

• Remote status signaling

• Control-circuit interlocking

• Panel indication

Normally Closed Contact

The NC contact is closed in its normal condition and opens when the auxiliary mechanism is actuated.

It can be used for:

• “Switch OFF” indication

• Interlocking

• Control-circuit logic

• Status feedback

• Monitoring circuits

The exact electrical function depends on the wiring and operating position of the main switch.

Designed for Superswitch 3KL84/3KA84

The 3KX3582-1YC is specifically associated with the larger Siemens Superswitch family:

• 3KL841

• 3KL842

• 3KL843

• 3KA843

• 3KA844

• 3KA845

• 3KA846

Siemens accessory documentation groups these devices under the same auxiliary-switch article.

The exact installed switch-disconnector should be checked before purchasing the accessory.

Auxiliary Signal from a Power Switch

A Superswitch auxiliary contact allows the status of the main switching device to be represented electrically in another circuit.

For example, when integrated correctly into a panel:

Superswitch position → Auxiliary contact changes state → Control/indication circuit receives the signal

This can be useful where a machine or electrical panel requires a local or remote indication of switch status.

Suitable for Industrial Electrical Panels

The 3KX3582-1YC can be relevant for compatible:

• Industrial distribution panels

• Switchboards

• Low-voltage switchgear

• Superswitch assemblies

• Electrical control panels

• Power-distribution equipment

• Maintenance and replacement applications

The auxiliary switch must be installed with its compatible Siemens Superswitch and wired according to the applicable electrical documentation.

Control and Interlocking Applications

The 1NO + 1NC arrangement provides flexibility for auxiliary logic.

The contacts can be used in compatible control circuits for:

• Electrical interlocking

• Status feedback

• Indication lamps

• Remote monitoring

• Circuit-permissive signals

• Panel control logic

The actual use should be determined by the circuit design and the electrical ratings of the auxiliary contacts.

Compatibility with Larger Superswitch Range

Siemens uses different auxiliary-switch articles for different Superswitch sizes.

The published accessory table shows:

This size-specific selection is important when ordering replacement accessories.

Auxiliary Switch Compared with Other Accessories

The 3KX3582-1YC is an electrical auxiliary-contact accessory and should not be confused with mechanical Superswitch accessories such as:

• Fuse cover

• Terminal cover

• Phase barrier

• Fuse-cover phase-barrier kit

• Front drive/handle

For example, Siemens lists 3KX8430-0AC as a fuse cover and 3KX8431-0AC as a terminal cover, while 3KX3582-1YC is the auxiliary switch.

Replacement Accessory

The 3KX3582-1YC is useful where an existing auxiliary contact on a compatible 3KL84/3KA84 Superswitch needs replacement or where auxiliary indication is being added to an existing installation.

Before ordering, verify:

• Exact Superswitch model

• Switch series

• Number of poles

• Auxiliary-contact requirement

• Mechanical mounting arrangement

• Contact function

• Electrical contact ratings

This helps avoid selecting a visually similar accessory intended for another Superswitch size.

Standardized Siemens Accessory Range

The Siemens accessory range also includes a 2NO + 2NC version for the same larger Superswitch family:

3KX3582-1YD – Auxiliary Switch (2NO + 2NC).

This provides an alternative where a larger number of auxiliary contacts is required.

Standard Package Quantity

Siemens pricing documentation lists the 3KX3582-1YC with a standard package quantity of 1 piece.

This makes it suitable for individual maintenance, replacement and accessory procurement.

Industrial Procurement Applications

The 3KX3582-1YC is relevant for:

• Electrical panel builders

• Industrial buyers

• Maintenance departments

• Electrical contractors

• Switchgear assemblers

• Electrical product dealers

• Replacement-part procurement

• Industrial electrical maintenance teams

For SB Smart, the product is positioned around industrial electrical product supply and procurement, without claiming automation integration or automation-service work.
