Why Choose the ABB 1SAL103355R9906 MARN413AR Auxiliary Contact?
The ABB 1SAL103355R9906 (MARN413AR) is a compact and reliable front-mounted auxiliary contact block designed for switching auxiliary and control circuits in industrial automation applications. Featuring 1 normally open (NO) and 3 normally closed (NC) contacts, it provides four additional instantaneous contacts for expanding the control, signalling and interlocking capabilities of compatible ABB mini contactors and mini contactor relays.
As part of ABB's M mini contactor accessory range, the MARN413AR is designed for front mounting on ABB MCR mini contactor relays and MC1 and MC2 mini contactors. Its clip-on construction provides straightforward installation, while the four-pole contact arrangement is particularly useful for control circuits requiring multiple normally closed contacts for interlocking, status monitoring and sequencing functions.
The MARN413AR uses ring tongue terminal connections for secure industrial wiring and features contacts designated in accordance with EN 50005. With a conventional free-air thermal current of 10 A and a rated operational current of 6 A at 230 V AC in AC-15 applications, it provides dependable auxiliary switching for industrial control systems.

Reliable Auxiliary Switching for Industrial Control
Auxiliary contact blocks such as the ABB MARN413AR expand a contactor or contactor relay with additional electrical contacts for control and signalling purposes. These contacts can be incorporated into interlocking, indication, sequencing and monitoring circuits, enabling sophisticated machine control without requiring separate switching devices for every auxiliary function.
The MARN413AR provides one normally open and three normally closed instantaneous contacts in a compact front-mounted assembly. Its compatibility with ABB MCR mini contactor relays and MC1 and MC2 mini contactors makes it a practical accessory for machine builders, panel builders and automation engineers requiring additional control contacts while maintaining a compact installation.
Typical Applications
- Industrial control and automation panels.
- Motor starter and contactor control circuits.
- Electrical interlocking systems.
- Contactor status and position signalling.
- PLC and machine control interfaces.
- OEM machinery and production equipment.
