Voltage and suppression type
The LA4KE1B suppressor module from Schneider's TeSys K series uses a varistor to clamp transients on 12 to 24 V AC/DC circuits — the voltage range that covers most PLC and relay outputs in industrial control panels.
Panel-fit dimensions
At 6 mm wide, 22 mm deep, and 25 mm tall, this module clips directly onto a DIN rail without stealing extra space — a practical choice when you're packing contacts into a crowded enclosure.
Environmental limits
Rated for -25 °C to 50 °C ambient, the LA4KE1B holds up in unheated cabinets or rooftop installations where temperature swings are a real concern.
