[Universal circuit breaker]ME630 type universal circuit breaker

2026-6-10 10:06:40

Purpose:
The ME630 universal circuit breaker is a product imported from AGE GmbH in the Federal Republic of Germany. The circuit breaker is suitable for rated working voltages ranging from A.C to 380V, 660V, 50Hz; The distribution circuit with a rated working current of 630A-3900A is used for infrequent conversion and protection against overload, undervoltage, and short circuit of the line and electrical equipment. And it has graded selection protection. It can directly start the motor and protect the motor, generator, rectifier device, etc. from abnormal conditions such as overload, short circuit, and undervoltage.
The ME series universal circuit breaker (intelligent type) is based on the ME series universal circuit breaker and is composed of an intelligent trip unit with a microprocessor. It has selective three-stage protection, easy debugging, and reliable operation.

characteristic
The ME630 universal circuit breaker has a compact structure, small size, light weight, and strong series. Good interchangeability of components, complete protection system, high technical and economic indicators, and easy maintenance and use.
Technical standards and normal working conditions
Compliant with IEC947, VDE0660, GB14048.2
type
Installation method: fixed type, drawer type
Number of poles: three poles, four poles
Operation method
The ME630 universal circuit breaker has a right-hand manual direct operation mode; Direct manual operation on the front side; Front manual quick operation; Quick operation of electric motor; There are five ways to operate electric motors for energy storage.
The operation of the electric motor with energy storage and release is divided into two processes: the first process is energy storage, which can be completed by simply operating the energy storage button. The second process is the closing operation. When the circuit breaker needs to be closed, simply turn on the closing operation button to complete it. The time from receiving the closure order to completing the closure operation is about 100ms.

[Universal circuit breaker]RMW15HH series universal circuit breaker

2026-6-10 10:06:23

The RMW15HH series universal circuit breaker is a product developed by the factory in the 1990s, with a rated voltage of AC 50HZ, 400V, and a rated current of 630-4000A. It is used in distribution networks to distribute electrical energy and protect lines and power equipment from overload, undervoltage, short and neutral, single-phase grounding and other faults. Under normal conditions, it can also be used for infrequent switching of lines. Selective protection with high precision improves power supply reliability.

Usage and classification
2.1 Purpose
The DW15HH series universal circuit breaker has a rated current of 630A to 4000A and a rated working voltage of AC 400V, 50HZ. Mainly used in distribution networks to distribute electrical energy, protect lines and power equipment from the hazards of overload, undervoltage, short circuit, single-phase grounding and other faults. Under normal conditions, it can also be used for infrequent switching of lines. It can achieve selective protection and precise action to avoid unnecessary power outages, improving the reliability of power supply.
2.2 Classification
1. Rated current meter of circuit breaker

Inm(A)	two thousand	four thousand
In(A)	630, 800, 1000, 1600, 2000	2000, 2500, 3200, 4000

2. Table of rated working voltage, rated short-circuit breaking capacity, arcing distance and incoming line method of circuit breaker

Inm(A)	Ue=400V			flying arc distance	incoming line method
Icu	Isc	Icw 1-second delay 0.4s o-oc
two thousand	50(cos��=0.25)	40(cos��=0.25)	40(cos��=0.25)	50mm	Up line or bottom entry
four thousand	80(cos��=0.25)	60(cos��=0.25)	60(cos��=0.25)
Note: When Inm=2000A and Ue=690V, the rated ultimate short-circuit breaking capacity Icu=30KA, Cos ��=0.25, the arcing distance and incoming line method are the same as above. If the user needs a circuit breaker with Ue=690, they can negotiate with us.
