Square D 9038AG1 alternator liquid level switch is designed to monitor and control liquid levels in various industrial applications. It is used in tanks, reservoirs and other liquid storage systems to prevent overflows or shortages. This CSA-certified switch features screw clamp electrical connections for easy installation and secure connections. It is suitable for operation within a voltage range of 120VAC to 600VAC. This switch offers open tank mounting to allow easy installation onto open tanks and streamlining setup. It is designed to handle a maximum current of 10A. It features a DPST (double pole, single throw) contact configuration, ensuring reliable control and switching capabilities. This NEMA rating 1 switch can operate effectively in temperatures ranging from -22 to 220 degrees F and has a close-on-rise switch function. It features steel construction to ensure robustness and longevity in industrial environments.

Working Mechanism:

• This switch utilises a float mechanism that rises or falls with the liquid level.
• When the level reaches a certain point, the switch activates, triggering pumps, alarms or other related systems.
• This maintains optimal liquid levels, prevents equipment damage and ensures efficient processes.
• Its versatility and reliability make it a preferred choice in industries, such as water management, manufacturing and chemical processing.

Frequently Asked Questions:

Q. What does close on rise mean for this switch?

A. Close on rise refers to the switch's function where the electrical contacts close (make contact) when the liquid level rises and reaches the preset level. This action triggers associated systems, such as pumps or alarms.

Q. Can this switch handle different motor types and sizes?

A. Yes, the switch is adaptable to different motor types and sizes. It supports motors up to 2 HP at 120VAC (single-phase), 3 HP at 240VAC (single-phase) and 5 HP at 240VAC (three-phase).

Q. Can the switch be used with different conduit sizes?

A. Yes, this switch is compatible with conduit sizes of 4-1/2 and 4-3/4 inches, offering flexibility in conduit selection during installation.

Q. What is the purpose of the NEMA 1 rating?

A. The NEMA 1 rating indicates that the switch is suitable for indoor use & provides protection against solid foreign objects, making it ideal for indoor industrial settings.
