Data Sheet DIN Rail Miniature Circuit Breakers Ex9 Series B Ex9BE3C0 Ex9BHC6 www.noarkus.com
NORK Ex9 Series B NORK Miniature Circuit Breakers offer these advantages: highperformance, small size, exemplary protection, easy DIN rail installation, fast wiring utilizing double terminal technology and ring tongue terminals. The integrated captive connecting screws simplify the connection process. The NORK BN/BH/B series is UL listed for 489 and 489 applications, as well as CS C. No.. The NORK BE Series is UL 077 for Supplemental Protector applications while also complying with both CS C. No. 3 and IEC 60947 and UL 486 standard for connection terminals which allows the user to apply field wiring directly to the breaker. NORK MCBs fulfill North merican and global approval requirements. Our global circuit breakers are a perfect fit for OEMs building global equipment.
