TRA4-12VDC-S-H
TRA4 10A power relay with 12V DC coil, TV-5 rating for appliance applications
Product Overview
Description
The TRA4 is a 10A power relay designed for appliance, HVAC, CTV, monitor, and emergency lighting applications. It features UL TV-5 rating for enhanced safety in appliance applications.
With 1 Form A (SPST-NO) contact arrangement and silver alloy contacts, the TRA4 provides reliable switching of resistive loads up to 10A at 250VAC or 30VDC. The TV-5 rating (5A at 120VAC) ensures safe switching of tungsten lamp loads.
The relay features high dielectric strength of 4000VAC between contacts and coil, with 900VAC between open contacts. Available in sealed (S) and flux-tight (C) versions for different environmental requirements.
