Introduction
DZ47-63 high breaking miniature circuit breaker has the
characteristics of advanced and reasonable structure, reliable
performance, high breaking capacity, beautiful and compact
appearance, etc.
Point, shell and other components are made of impact-resistant,
highly flame-retardant materials. Suitable for AC 50Hz or 60Hz,
rated working voltage 400V or less
The rated current is below 6A to 63A. Mainly used for lighting,
distribution lines and office buildings, residential and similar
buildings
The overload and short circuit protection of the equipment can also
be used for infrequent breaking and conversion of the line under
normal circumstances.
This product conforms to standards: IEC60898 and GB 10963.
Structural characteristics
DZ47-63 high breaking miniature circuit breaker is composed of
plastic shell, operating mechanism, contact arc extinguishing
system, trip mechanism, etc. Shell used
High-flame-retardant, high-strength special plastics with strong
impact resistance and light weight.
The parts of the circuit breaker operating mechanism are made of
high-strength plastic products, which ensure the sensitivity and
reliability while obtaining the lowest moment of inertia.
The time from the start of the short-circuit fault to the tripping
mechanism is very short. The tripping mechanism consists of a
bimetallic overload, inverse time tripping mechanism and
short-circuit transient action
The electromagnetic mechanism is composed of two parts. The contact
arc extinguishing system uses a special arc guide angle and arc
extinguishing chamber, which has significant current limiting
characteristics.
