MARS compact open construction transformers are less than 2-1/4" in height. This makes them ideal as replacements within existing equipment. MARS control transformers are available with various outputs and voltages for special applications.
Features:
- UL class 2 recognized
- Low heat rise
- Primary color coded leads
- Secondary color coded leads, or 1/4" male quick connects
- Foot-mount
Â
Compatibility & Applications:
- Intended for use in air conditioners, heat pumps, and other HVAC equipment requiring a 2-pole, 40 amp, 24V coil contactor
- Suitable for residential and light commercial outdoor units, air handlers, and other equipment within the contactor's ratings
- Used as a replacement where equipment specifications call for a 2-pole contactor with similar electrical ratings and coil voltage
Installation & Operation Notes:
- Disconnect power at all sources and verify that all circuits are de-energized before starting work
- Mount the contactor securely in the control compartment or electrical panel as directed by the equipment manufacturer
- Move line, load, and control wires from the existing contactor to the new contactor, matching wiring diagrams and terminal markings
- After energizing the system, verify that the contactor pulls in and opens cleanly, with proper operation during system start and stop cycles
- Confirm that all terminations are tight and that wiring is supported to prevent strain at the terminals
Maintenance & Troubleshooting:
- Inspect the contactor during routine HVAC maintenance for pitted or burned contacts, coil discoloration, or mechanical binding
- Replace the contactor if the coil fails to energize, if the contacts do not close fully, or if there is evidence of overheating or excessive humming
- If repeated contactor issues occur, verify that load current and control voltage are within specification and that short cycling is not overstressing the contactor
Certifications & Compliance:
- Meets ARI 780/790 Standard
User Reviews & Q&A Summary:
- Common theme is "correct part" for the intended replacement, with users reporting it worked as expected after installation
- Review feedback frequently mentions straightforward installation for a direct replacement
- Value and fulfillment are recurring positives (good deal/price and fast shipping)
