Eaton Cutler-hammer HT8JAH3A 2-position Selector Switch

Product Description

The EATON CUTLER-HAMMER HT8JAH3A is a 2-position maintained selector switch designed for industrial control panel applications. The switch uses a black knob operator and holds its selected position without spring return, making it suitable for circuits that require a stable on or off state without operator input. Both positions are maintained, meaning the knob stays where it is set until manually moved. The unit carries an IP65 ingress protection rating and meets NEMA 12, 13, 3, 3R, 4, and 4X enclosure standards, providing oil-tight and water-resistant performance in demanding environments. It is non-illuminated and rated to UL 508 and CSA C22.2 No. 14 standards.

This selector switch is used in industrial and commercial control panels where a durable, manually operated switching element is required. Typical applications include machine control stations, motor control centers, and automation panels exposed to dust, coolant, or wash-down conditions. The NEMA 4X rating makes it appropriate for corrosive or wet environments such as food processing, chemical handling, and outdoor industrial enclosures. Licensed electricians and controls technicians are the typical installers for this type of device.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and the panel manufacturer's documentation. De-energize and lock out the control panel before removing or installing the switch. Verify that the panel cutout dimensions match the switch operator footprint before mounting. Do not defeat the IP65 sealing features during installation, as doing so will compromise the ingress protection rating.
