MARS 61610 Auxiliary Switch

The MARS 61610 Auxiliary Switch is a high-performance side-mount auxiliary contact engineered for seamless integration with 25-60 amp definite purpose contactors. Built for the rigors of commercial refrigeration and industrial HVAC systems, this 1 N/O (Normally Open) interlock switch provides reliable mechanical linkage to the main contactor armature. This allows for precise signaling and control logic, such as confirming the contactor's state to a PLC or managing a secondary circuit without adding significant electrical stress to the primary control components.

Constructed with durable materials to withstand harsh environments, the MARS 61610 features a snap-on design that ensures a secure fit on the side of 3-pole contactors, significantly reducing field installation time. With a current rating of 25/60A, it effectively handles auxiliary loads across a variety of HVACR motor control applications. Whether you are implementing interlocking safety protocols or monitoring system status for remote diagnostics, this auxiliary interlock switch delivers the mechanical precision required by veteran technicians and electrical contractors.

• Universal Compatibility: Designed specifically for use with 25A to 60A 3-pole definite purpose contactors.
• Snap-On Installation: Side-mounting configuration allows for rapid, tool-free field attachment to existing HVACR contactors.
• Reliable Signaling: The 1 N/O (Normally Open) contact configuration provides a clean circuit closure for system feedback and secondary load control.
• Enclosed Construction: Totally enclosed switch housing protects internal contacts from dust and environmental contaminants commonly found in mechanical rooms.

What is the primary function of the MARS 61610 in a control circuit?
It serves as a secondary signaling device that changes state simultaneously with the main contactor, allowing you to trigger interlocks, indicator lights, or low-voltage control signals without drawing through the main power poles.

Is the 61610 compatible with all contactor brands?
This auxiliary switch is engineered for MARS 780 series and comparable professional-grade definite purpose contactors in the 25A to 60A range. Always verify physical mounting patterns before installation.

Can this be used for a normally closed (N/C) application?
No, the 61610 is specifically a 1 N/O configuration. For applications requiring a normally closed circuit, the MARS 61611 should be utilized.
