Miniature Circuit Breaker

1.Application

TFDZ47_100 is such features as delicate appearance, light weight, excellent and reliable performance, high breaking capacity, rapid tripping and mounted by rail. Its Enclosure and components adopts high fire-retarding and shockresistance plastic of long durability. It mainly serves for protecting the circuits of AC 50Hz, 230V of single pole, 400V of two poles or three or four poles from overload or short circuit, and also for unfrequented making and breaking electrical apparatus and lighting circuit. It conforms to the standards of IEC60947-2.


2. The over-current protection property

Ambient Temperature	Initial Status	Test Current	Expected Result	Expected Result	Note
40±2℃	Cold position	1.05In(In≤63A)	t≤1h	Non-release	--
	Cold position	1.05In(In＞63A)	t≤2h	Non-release	--
	Carried out immediately after previous test	1.30In(In≤63A)	t≤1h	Release	Current smoothly rises to specified value within 5s
		1.30In(In≤63A)	t≤2h	Release
-5 - +40℃	Cold position	8.00In	t≤0.2s	Non-release	--
	Cold position	12.00In	t≤0.2s	Non-release	--
