## Description

The TE Connectivity MPN 1415035-1 (Model MT 78 750) is an 11-pin general-purpose relay socket engineered for the MT Series multimode relay ecosystem. Designed for secure snap-on mounting onto standard DIN-rails or screw mounting in control panels and industrial automation enclosures, this socket features a logical input-and-output connection layout that streamlines panel wiring and maintenance procedures. The integrated screw-type terminals utilize Pozidrive screws equipped with rising clamps, accommodating single wires, fine wires, and bootlace crimps up to 2 x 2.5 mm² per terminal. 

Electrically, the MT 78 750 socket is rated for a continuous operating current of 10 A with a maximum switching voltage of 400 VAC (240/400 VAC rated voltage system). It delivers robust dielectric strength characteristics, offering 2500 Vrms between the coil-contact and adjacent contact circuits, and 1500 Vrms across open contact circuits. Compliance with IEC 60664-1 establishes a rated insulation voltage of 250 V within Overvoltage Category III and Pollution Degree 2. With a creepage and clearance distance of ≥ 2.8/4 mm between the coil and contact circuits, along with an operational ambient temperature range of -20°C to +80°C, this relay accessory provides reliable performance in demanding industrial power distribution and switching applications.
