Product Information
Full details
This Schneider Electric TeSys Surge Suppressor (LAD4RCE) is designed for users of LC1D09-D38 and LC1DT20-DT40 contactors and CAD control relays. Its key benefit is protecting these components from transient voltage spikes, thereby extending their service life and the life of connected devices. A potential caveat is its specific operating voltage range of 24-48V AC, requiring careful compatibility checks. This module offers crucial protection against high-frequency interference and voltage surges, ensuring reliable operation in demanding environments.

Extended Product Information
FAQs
What is the primary function of the LAD4RCE surge suppressor?
The LAD4RCE is designed to protect compatible contactors and control relays from damage caused by transient voltage spikes and high-frequency interference, thereby extending their operational lifespan.
What is the compatible control voltage for this surge suppressor?
This surge suppressor is compatible with control voltages in the AC range of 24 to 48 Volts (V AC).
Which Schneider Electric contactors and relays can this module be used with?
It is designed for use with LC1D09-D38 and LC1DT20-DT40 contactors, and CAD control relays.
How is the LAD4RCE installed?
The module features a simple snap-on design for easy side mounting onto compatible contactor or relay units.
What is the operating temperature range for this device?
The LAD4RCE can operate reliably in ambient temperatures ranging from -25°C to +55°C.
Does this surge suppressor offer protection against sustained overvoltage?
No, this RC suppressor is designed specifically to limit transient voltage spikes (short-duration surges). It does not provide protection against sustained overvoltage conditions.
What does the IP2x rating mean for this product?
The IP2x rating signifies that the device is protected against solid objects larger than 12.5 mm (like fingers) and is touch-proof, but it does not provide protection against dust or water ingress.
Troubleshooting
Module not suppressing voltage spikes.
Verify the module is correctly installed on a compatible contactor or relay. Ensure the control voltage supplied is within the 24-48V AC range and matches the module's specifications. Check for any visible damage to the module or wiring.
Contactor or relay failing prematurely despite module installation.
Confirm the module is functioning by checking its connection and ensuring it's not overloaded. The issue might stem from voltage spikes exceeding the suppressor's capability (beyond 3 Uc) or other environmental factors. Consult the contactor's manual for combined usage limitations.
Module overheating.
Ensure the ambient temperature is within the -25°C to +55°C range. Check for proper ventilation around the contactor and module. Overheating may indicate a fault within the module or excessive, sustained voltage issues that the suppressor is not designed to handle.
Pros and Cons
Pros
- Provides essential protection against damaging voltage transients.
- Easy to install with a snap-on mechanism, saving time.
- Compact design maintains the original footprint of the contactor.
- Operates across a wide temperature range for industrial reliability.
- Protects both the contactor and connected equipment, enhancing longevity.
Cons
- Limited to specific LC1 and LC2 series contactors and CAD relays.
- Requires a 24-48V AC control voltage, limiting universal application.
- Does not offer protection against sustained overvoltage, only transient surges.
Setup, Compatibility & Care
Setup:
The LAD4RCE surge suppressor is designed for straightforward clip-on side mounting. It attaches directly to the side of compatible LC1D09-D38, LC1DT20-DT40 contactors, and CAD control relays. Ensure the control voltage is within the 24-48V AC range before installation.
Compatibility:
- Contactors: LC1D09-D38, LC1DT20-DT40 series.
- Control Relays: CAD series.
- Control Voltage: 24-48V AC at 50 or 60 Hz.
Care:
This is a passive component with no user-serviceable parts. No specific cleaning or maintenance is typically required beyond ensuring connections remain secure and free from dust or debris. Avoid exposing the unit to conditions outside its specified operating temperature range (-25°C to +55°C). Its IP2x rating provides protection against finger contact but it is not sealed against dust ingress or water.
