Schneider Electric LA7D03F Remote Trip Accessory

Product Description

The SCHNEIDER ELECTRIC LA7D03F is an electrical remote trip accessory designed for use with TeSys series thermal overload relays and circuit breakers. It allows remote electrical actuation of a trip signal, enabling the connected device to be tripped from a separate control point without direct mechanical intervention. This is especially useful in panel or machine control applications where remote shutdown capability is required. Licensed electricians and industrial control panel builders typically install this component as part of a motor protection or control assembly. The LA7D03F ships as a single unit and is a compact, low-profile accessory.

The LA7D03F is used in industrial and commercial electrical control panels where TeSys overload relay assemblies are employed for motor protection. It is compatible with LR2D, LR3D15, LR3D33, LR3D35, LR3D43, LRD15, LRD33, and LRD43 series overload relays, as well as the broader TeSys product family. Typical installation scenarios include conveyor systems, pump controls, HVAC motor starters, and other motor-driven equipment requiring reliable remote trip or emergency stop functionality.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements and the panel manufacturer guidelines. De-energize the control panel and verify the absence of voltage before attaching or removing this accessory. Ensure the accessory is fully seated and secured to the host relay before restoring power. Do not exceed the electrical ratings of the host overload relay when wiring the remote trip input.
