Product Description

MCB Nova DAB7-63 10ka 3p Mini Circuit Breaker

Introduction
 

Miniature circuit breakers NOVA DAB7-63 are intended for providing automatic power source cut-off under excess currents.They are recommended for use in group panels (apartment and floor) and distribution boards of residential, domestic, public and administrative buildings. 64 items per 8 rated currents ranging from 6 to 63 A. This MCB has been obtained ASTA, SEMKO,CB,CE certificate.

Advantages
 

• Two types of overcurrent protection - thermal and electromagnetic.
• Independent contact position indicator.
• DIN rail latch with a double fixed position.
• Wide range of operating temperatures from -40 to +50° С.
• Wide engagement lever with improved contact area.

Notches on terminal clamps lower thermal losses and boost the mechanical stability of connection.
