MARS
Frequently asked questions
Common questions about MARS from 3G Electric.
What are the electrical specifications of MARS air curtain motor control panels?
MARS air curtain motor control panels are available in several electrical configurations. They are rated for three-phase power at 208/230V AC, 460V AC, or dual-rated 208/230/460V AC. Current ratings range from 1.6 A to 24.9 A, depending on the specific model. For example, the 19-102 panel is rated 460V AC, 3 Ph, 1.6 A, while the 19-114 panel is rated 208/230V AC, 3 Ph, 24.9 A. All panels feature a steel NEMA 1 enclosure suitable for indoor use. The correct panel must be selected based on the voltage and current requirements of the air curtain motor it will control.
What is the difference between MARS motor control panel part numbers 19-101 and 19-102?
The MARS 19-101 and 19-102 motor control panels differ primarily in their voltage and current ratings. The 19-101 is rated for 208/230V AC, three-phase, 3.3 A, while the 19-102 is rated for 460V AC, three-phase, 1.6 A. Both use a steel NEMA 1 enclosure and have dimensions of 6 3/8 in x 10 3/8 in x 10 3/8 in. They are designed for different air curtain models and electrical supply configurations. When replacing a control panel, verify the voltage and current ratings match the original equipment specifications to ensure compatibility and safe operation.
Are MARS air curtain motor control panels compatible with all MARS air curtain models?
No, MARS motor control panels are designed for specific air curtain models and electrical requirements. Compatibility depends on the voltage, phase, and current rating of the air curtain motor. Each control panel has a defined current range and voltage rating, and must be matched to the air curtain it controls. For instance, a panel rated 460V AC, 3.2 A (19-115) is not interchangeable with a panel rated 208/230V AC, 24.9 A (19-114). The product documentation lists compatible part numbers for each panel. Always consult the air curtain's nameplate data and the control panel specifications to ensure proper selection.
What enclosure type do MARS motor control panels use?
MARS motor control panels for air curtains use a NEMA 1 enclosure made of steel. NEMA 1 enclosures are intended for indoor use and provide protection against limited amounts of falling dirt and dust. They are not rated for outdoor or wet locations. The panels are available in two sizes: 6 3/8 in x 10 3/8 in x 10 3/8 in and 6 3/8 in x 12 3/8 in x 12 3/8 in. The enclosure houses the switching components, overload protection, and voltage regulation elements. For installations requiring higher environmental protection, additional enclosures or modifications may be necessary.
What replacement parts does 3G Electric offer for MARS air curtains?
3G Electric supplies a range of replacement parts for MARS air curtains, including motor control panels and motor fan assemblies. Motor control panels are available in multiple part numbers (e.g., 19-101, 19-102, 19-112, 19-114, 19-115, 19-116, 19-117, 19-118) with various voltage and current ratings. Motor fan assemblies include the motor, fan blade, and housing, and are specific to air curtain models. These components allow for repair and maintenance of existing installations. 3G Electric provides specifications and compatibility information to help identify the correct replacement part. For assistance, contact 3G Electric with the air curtain model and serial number.
