Overview
The LAERCN is a Schneider Easy TeSys suppressor module, order code LAERCN, built as an RC circuit rated for 380-415 V coil voltage. It is designed for front mounting, measures 33 mm deep by 44 mm wide, carries an IP20 rating, and complies with IEC 60947-5-1.
Function & operation
This suppressor module uses an RC circuit to damp voltage transients across the contactor coil, reducing electromagnetic interference and extending contact life. The 415 V coil voltage rating matches the control supply of LC1E06...E95 contactors in the Easy TeSys range. The RC circuit is a passive snubber — no polarity concerns, and it dissipates stored coil energy as heat rather than a voltage spike. The module carries GOST certification and conforms to TH protective treatment per IEC 60068, indicating suitability for tropical environments. The IP20 enclosure allows installation inside a standard panel enclosure.
Applications
Suppressor modules of this type are used across industrial control panels, motor control centers, and OEM machinery where AC contactors switch inductive loads. The RC circuit suppresses arcing at contact opening, which is critical for maintaining contactor reliability in high-cycle applications such as conveyor systems, pump stations, and packaging lines.
Lifecycle & availability
The LAERCN is officially discontinued by Schneider, with a discontinuation date of 2024-12-01. This means the part is no longer in active production and is not available through standard distribution channels. Buyers needing this module should source from surplus or broker inventories. No official successor part number is listed in the available documentation.
