Hammond 1437a Pushbutton Enclosure Nema 12 13 Steel Gray

Product Description

The HAMMOND 1437a is an extra-deep, single-hole pushbutton enclosure designed for industrial control applications where protection against dirt, dust, oil, and water is required. Formed from 16-gauge mild steel with a powder-coated finish over a phosphatized surface in ANSI/ASA 61 gray, this enclosure meets NEMA 12 and 13 ratings along with IP65 certification. It measures 4 inches wide by 4 inches tall by 4.75 inches deep, providing 76 cubic inches of interior capacity. Licensed electricians and industrial maintenance technicians install this unit in panel shops, machine tool installations, and similar indoor environments where fluid and particulate ingress protection is essential.

This enclosure is suited for residential and commercial indoor control stations housing pilot lights, pushbuttons, and selector switches. The single vertical device hole is sized at 1.21 inches in diameter to accept 30.5mm operators. It is part of the Hammond 1437 Series and is intended for applications where condensing oils or coolant mist exposure demands a sealed housing. The bracket-mount configuration allows direct wall or panel surface installation without requiring a subpanel cutout.

Key Features

• Extra-deep housing at 4.75 inches depth provides additional wiring room behind the operator

• Powder-coated finish over phosphatized surface resists corrosion in industrial environments
• Oil-resistant gasket with adhesive backing ensures a sealed, gasketed screw-on cover
• Captive cover screws fasten into threaded, sealed wells to prevent hardware loss during service
• Grounding stud on enclosure body and bonding stud on door included for electrical safety compliance

Compatibility

Designed as an OEM-style replacement or new-install enclosure for single-operator 30.5mm pushbutton, pilot light, or selector switch applications in NEMA 12 and 13 rated indoor industrial control stations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits and lock out the power source before opening or wiring the enclosure. Use appropriate conduit fittings rated for NEMA 12 or 13 service to maintain the enclosure's ingress protection rating at all entry points. Do not field-drill additional holes without verifying that proper sealing methods are applied to preserve the rated protection level.
