Description

TeSys Deca suppressor module, for contactors LC1D09-D38, LC1DT20-DT40 and control relays CAD. To be used with 5-600V DC control circuit voltage, it provides a flywheel diode protection ensuring no transient overvoltage. Clip-on side mounting, overall size of the contactor is unchanged.

Features

Engineered with high-efficiency flywheel diode technology, the LAD4DDL safely suppresses the massive transient counter-EMF spikes generated when a contactor coil is de-energized. By strictly limiting peak voltage to 1 U_c, it safeguards nearby solid-state automation equipment, PLCs, and digital I/O modules from electrical noise interference or terminal breakdow
Boasting an ultra-wide operational footprint from 5V to 600V DC, this versatile suppressor module seamlessly integrates with standard 12V, 24V, 48V, or high-voltage DC control circuits. This broad compatibility eliminates the need to source and stock multiple voltage-specific surge arresters, drastically simplifying your control panel bill of materials (BOM)
This module is purpose-built for a perfect mechanical fit with Schneider Electric 3-pole LC1D09 to LC1D38 contactors, 4-pole LC1DT20 to LC1DT40 contactors, and CAD32/CAD50 control relays. This targeted architectural integration prevents mechanical misfits and ensures robust, reliable terminal alignment across your entire motor control lineup.
Designed with an innovative, snap-on clip mechanism, the module mounts securely to the side of the contactor without requiring screws or specialized tools. This rapid interface architecture reduces field wiring labor costs while keeping the overall front footprint of your TeSys Deca device completely unchanged, optimizing high-density DIN rail spacing.
Fully certified to UL 60947-5-1, CSA C22.2, IEC 60947-5-1, and CE standards, this suppressor module meets the strict safety benchmarks required for heavy industrial deployment. Incorporating an IP2X touch-safe housing, it guarantees reliable risk mitigation against accidental finger contact while keeping your automation panels completely
