Schneider 31114 Compact INS630 Switch Disconnector 3P 630A

The Schneider Electric 31114 is a Compact INS630 three-pole switch disconnector rated 630 A, suitable as a main or auxiliary on-load isolator in AC and DC distribution boards. It is operated by a direct front rotary handle (black) and provides full isolation with a positive contact-position indicator, conforming to IEC 60947-3 / IEC 60947-1. Rated for AC-23A duty up to 690 V AC and 125 V DC service, it delivers a short-time withstand of 20 kA for 1 s and 11.5 kA for 3 s, and is suitable for fixed mounting on rail or plate.
