DAB7-63H series Miniature Circuit breaker(MCB)

Introduction

image002.jpg10KA 

Miniature circuit breakers DAB7-63H 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.

•High Breaker capacity 10KA

•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.

Design Features
