Telemecanique 9036DW31R Open Tank Float Switch Nema 4

Product Description

The TELEMECANIQUE 9036DW31R is an open tank float switch designed to control pump motors and liquid-level applications in industrial and commercial environments. It features a single-lever operator with a 2NO-DPST (double-pole single-throw, normally open) contact configuration, providing reliable level sensing in wet or wash-down conditions. The enclosure is rated NEMA 4 and constructed from cast aluminum, making it suitable for demanding service where moisture and corrosion resistance are required. Terminal connections use a screw-clamp design for secure field wiring. The motor power rating is 3.7 kW at 230 VAC 3-phase, and the switch is listed under UL 50, UL 508, and CE approvals.

This float switch is intended for open tank installations in industrial pump control, water and wastewater systems, sump applications, and process liquid management. It is appropriate where a NEMA 4 rated enclosure is specified for indoor or outdoor use with exposure to hose-directed water or similar wash-down conditions. Licensed electricians and industrial maintenance technicians are the typical installers. The operating temperature range of -22 to 220 degrees F makes it suitable for a broad range of process fluid temperatures.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Disconnect and lock out all power to the circuit before wiring or servicing the switch. Screw-clamp terminals should be torqued only to the terminal manufacturer specification indicated on the device or documentation supplied with the unit. Verify the float arm orientation and trip point adjustment match the required liquid level setpoint before returning the system to service.
