1SAL100988R9906 ABB MARN413AT Mini Contactor Relay 1NO 3NC Control Relay

Why Choose the ABB MARN413AT 1SAL100988R9906 Auxiliary Contact?

The ABB MARN413AT 1SAL100988R9906 is a compact and reliable four-pole auxiliary contact block designed for switching auxiliary and control circuits in standard industrial environments. As part of ABB's miniature contactor accessory range, it provides 1 normally open (NO) and 3 normally closed (NC) contacts for signalling, interlocking and control functions.

Designed for front mounting, the MARN413AT uses screw terminals to provide secure electrical connections. The contact arrangement follows EN 50005, helping provide standardised terminal identification for industrial control and automation installations.

With a conventional free-air thermal current of 10 A and a rated operational current of 6 A at AC-15, 230 V, the MARN413AT is suitable for a wide range of industrial auxiliary and control circuit applications. Its compact 27 × 45 × 35 mm dimensions make it well suited to control panels and machinery where installation space is limited.

Key Advantages

• Compact four-pole auxiliary contact block for industrial control circuits.
• 1NO/3NC contact configuration for flexible signalling and interlocking.
• Front-mounted design for straightforward installation.
• Secure and familiar screw terminal connections.
• 6 A rated operational current at AC-15, 230 V.
• Contact designation compliant with EN 50005.

Key Features

• ABB MARN413AT auxiliary contact block.
• 1 normally open and 3 normally closed contacts.
• 10 A conventional free-air thermal current.
• 6 A rated operational current at AC-15, 230 V.

• 0.8 N·m auxiliary circuit tightening torque.
• Maximum permitted operating altitude of 3000 m.

Reliable Auxiliary Control for Industrial Applications

Auxiliary contact blocks provide additional switching contacts for control, signalling and interlocking functions within electrical control systems. They allow the operating state of contactors and control circuits to be incorporated into machine logic without using the main power contacts for signalling duties.

The ABB MARN413AT combines four auxiliary contacts in a compact front-mounted format. Its 1NO/3NC configuration is particularly useful where multiple normally closed signals are required for control logic, status indication or electrical interlocking.

Typical Applications

• Industrial control and auxiliary circuits.
• Contactor status signalling.
• Electrical interlocking circuits.
• Machine control panels.
• Industrial automation systems.
• Motor control and switching assemblies.
