LC1-D40008

Schneider Electric's part LC1-D40008 is a contactor engineered for use with resistive loads and includes 4 poles. This device manages the rated operational voltage efficiently, handling up to 690 V AC within the frequency range of 25 to 400 Hz and 300 V DC. The rated operational current is 60 A when the operating temperature is below 60 °C, making it valuable for various electrical applications.

The control circuit requires 48 V AC at 50 or 60 Hz for proper functionality. This contactor has a configuration of 2 normally open (NO) contacts and 2 normally closed (NC) contacts. With a conventional free air thermal current rating of 60 A at 60 °C, the contactor ensures reliability in power management.

In terms of building capacity, the contactor features a rated making capacity of 800 A at 440 V and an average impedance of 1.5 mOhm at the Ith rating of 60 A at 50 Hz. Each pole dissipates approximately 5.4 W under AC-1 conditions, contributing to effective energy management. The heat dissipation during operation is noted as 4 to 5 W at 50/60 Hz, ensuring that the device remains within acceptable thermal limits.

Notably, the contactor is designed to meet overvoltage category III and pollution degree 3 specifications, making it suitable for various environmental conditions. Opening times span from 4 to 19 milliseconds, while closing times range from 12 to 26 milliseconds, facilitating swift operation in control applications.
