Schneider Electric (Square D) LA4DA2G Contactor/Relay Suppressor

Description

Schneider Electric (Square D) LA4DA2G Contactor/Relay Suppressor Overview

The Schneider Electric (Square D) LA4DA2G is a plug-in suppressor module engineered to protect contactor and relay coil circuits from damaging voltage transients and electromagnetic interference. Designed for use with TeSys series contactors and control relays, this suppressor mounts directly onto compatible coil terminals — no additional wiring or hardware required. By absorbing voltage spikes generated at coil de-energization, the LA4DA2G extends the service life of both the contactor/relay and surrounding control components, reducing nuisance trips and costly downtime in HVAC and industrial control panels.

Key Features

• Plug-in suppressor module for fast, tool-free installation on compatible TeSys contactors and relays
• Suppresses voltage spikes and transients generated during coil switching to protect sensitive control circuits
• Reduces electromagnetic interference (EMI) that can disrupt nearby electronic components
• Extends operational life of contactors, relays, and associated control wiring
• Compact, low-profile design fits within standard control panel enclosures
• Manufactured by Schneider Electric (Square D), a globally recognized leader in electrical control and automation

Applications

• HVAC control panels utilizing TeSys contactors and relays
• Motor control centers (MCCs) and industrial automation panels
• Commercial and light industrial electrical control systems
• Any application requiring coil transient suppression on compatible Schneider Electric TeSys devices

Why Choose the LA4DA2G?

Voltage transients produced when a contactor or relay coil is switched off can reach many times the nominal coil voltage, stressing insulation and shortening component life. The LA4DA2G suppressor clamps these spikes at the source, safeguarding programmable logic controllers (PLCs), building automation systems, and other sensitive electronics connected to the same control circuit. Its plug-in design means installation takes seconds, and its compatibility with the TeSys product family makes it the factory-recommended solution for Schneider Electric contactor and relay protection.
