MARS 61624 Auxiliary Switch
The MARS 61624 Auxiliary Switch is a heavy-duty, side-mounted electrical component designed for seamless integration with MARS 780 series definite purpose contactors. Engineered for 75-90 amp applications, this 1 NO auxiliary contact provides a reliable secondary control circuit that activates precisely when the primary contactor coil is energized. As a veteran-grade OEM HVAC replacement part, it ensures stable performance in demanding commercial refrigeration, air conditioning, and electric heating systems. The snap-on design allows for rapid field installation without additional hardware, facilitating immediate interlocking or status signaling. With a 6 amp inductive and 10 amp resistive rating at 50/60 Hz, the MARS 61624 manages secondary loads like indicator lights or alarms while preventing system overloads. Its robust construction features high-performance copper and brass conductors to maximize current carrying capacity, ensuring your 75-90 amp contactor switch operates efficiently under high-cycle conditions in industrial environments.
Key Benefits- Direct Compatibility: specifically engineered for 75-90 FLA MARS 780 and 910 series contactors.
- Normally Open Logic: provides a 1 NO configuration that closes upon primary actuation for reliable position feedback.
- Simplified Installation: features a snap-on side-mount design to reduce downtime during field service.
- Thermal Efficiency: high-grade copper and brass internal components minimize resistance and heat buildup.
- Versatile Signaling: rated for both inductive (6A) and resistive (10A) pilot duty, ideal for alarms and control interlocks.
Can I use this switch on a 40 amp contactor?
No, the MARS 61624 is physically and mechanically sized specifically for the larger frames of 75-90 amp contactors, typically the 780 series. For smaller contactors, a different MARS auxiliary block is required.
Does this provide both normally open and normally closed contacts?
No, this specific model (61624) is a single-pole, 1 NO (Normally Open) configuration. If your logic requires a NC contact for a "breaker open" signal, you will need to source the corresponding NC or dual-pole auxiliary block.
How many auxiliary switches can be mounted to a single contactor?
Most 75-90 amp contactors in this series support one auxiliary block on each side of the main housing, allowing you to stack or mirror controls depending on your specific bridge or interlocking requirements.
