MCB Nova DAB7-63 10ka 1p 2p 3p 4p Micro 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.
