Characteristic
TOBIZ-63 DC circuit breaker is made up of case, operation mechanism, thermal overloading trip, electromagnetic trip
contact system, arc system etc. It has overloading and short circuit protection, unique-design structure and strong
permanent magnetism arc system make the product has 6KA short circuit capability. Long mechanical life over 20000
times and beautiful shape. It can be connected with din rail named TH35-7.5 standard stainless type and has the below
personality: the handle is designed on the top of the front, people will feel safe and comfortable when operating. When
connecting, pay attention to “+, -” poles; The power goes in from the top and comes out from the underside which is
applied with power entrance character. Convenient for installation and saving cables. It is used for 440V circuit 3 poles
circuit breaker to connect front loop for two poles serial connection.
B Curve (3-5In) protection for people and big length cables in TN and IT systems
C Curve (5-10In) protection for resistive and inductive loads with low inrush current.
D Curve (10-14In) protection for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps)
