Struthers-Dunn M35A-120VAC Power Relay

The Struthers-Dunn M35A-120VAC Mercury Displacement Power Relay is a hermetically sealed, mercury-wetted power relay rated for 35 A with a 120 VAC coil (coil voltage nominally 120 VAC). It supports AC or DC coil options with nominal coil power of 7–28 VA (AC) or 3–9 W (DC), and operate/release times up to 50 ms / 80 ms. The device can switch up to 3PST with resistive ratings of 35 A at 120/240 VAC and 28 VDC, and it can drive motors up to 5 hp at 120 VAC (5 hp at 240 VAC) with continuous duty. It features a dielectric strength of 2650 Vrms across open contacts and between insulated points, insulation resistance of 1000 MΩ at 500 VAC, operating temperatures of -34 to 74 C (-30 to 165 F), storage from -40 to 105 C (-40 to 221 F), and an optional DIN rail adapter (16-MDRDIN-1) for mounting. Weight varies by configuration.
