Square D 9013FHG52J59 Pressure Switch 100-200 Psi

Product Description

The SQUARE D 9013FHG52J59 is an electromechanical pressure switch rated for 100 to 200 psi operation with a fixed differential pressure setting of up to 40 psi. Designed for use with Square D Pumptrol pump control systems, this switch monitors system pressure and opens or closes the circuit based on preset cut-in and cut-out thresholds. It is rated for 575 VAC and uses L1-T1 and L2-T2 terminal connections. Licensed electricians and pump service technicians install this switch in water pump systems where reliable pressure-based control is required. It carries NEMA 1 and NEMA 3R enclosure ratings, making it suitable for both indoor and protected outdoor installations.

This pressure switch is intended for use with Square D Pumptrol pump control applications, including residential and light commercial water well and booster pump systems. The NEMA 3R rating allows installation in locations subject to falling rain or sleet, which is common in pump house and utility room environments. It is a direct-fit replacement for existing Pumptrol-compatible installations requiring an electromechanical pressure switching solution with a fixed differential setting and a 100 to 200 psi pressure range.

• Rated for 575 VAC with L1-T1 and L2-T2 terminal configuration
• Electromechanical switching mechanism for reliable pressure-based pump control
• Meets CE, CSA LR25490, UL 508, UL Listed File E12158, and RoHS compliance standards
• Designed for use with Square D Pumptrol pump control systems

Compatibility

Designed for use with Square D Pumptrol pump control systems. Verify existing pressure range, differential setting, voltage rating, and terminal configuration before installation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and relieve system pressure completely before removing or installing any pressure switch. Confirm that the system operating pressure falls within the 100 to 200 psi range of this switch before commissioning. Do not adjust the fixed differential setting, as this switch is factory-set and not field-adjustable.
