M13 Moulded Case Circuit Breaker

Wholesale M13 Moulded Case Circuit Breaker manufacturer specialized in production and R&D M13 Molded Case Circuit Breaker (M13, hereinafter referred to as MCCB), is new circuit breakers which have been designed and developed by the company using international advanced technology. The circuit breakers are of the following characteristics: compact size, high breaking capacity, short arc-over distance and shakeproof, is ideal products applied on land or ships.


Scope of Application

XUCKY Electric is a large M13 Moulded Case Circuit Breaker manufacturer and supplier in China. For many years, we have been specializing in Modular Electrical Terminal Equipment, our products have good price advantage and cover most of the European and American markets. We are looking forward to being your long-term partner in China.

The rated insulation voltage of the circuit breaker is 800V (500V for M13-63), it is suitable for the distribution network of AC 50Hz / 60Hz, rated working voltage of 690V and rated current of 1250A, to distribute power and protect circuit and power equipment from being damaged caused by overload , short-circuit, under-voltage and other fault. Also for protection infrequent conversion of the circuits and infrequent start of motor and overload, short circuit, under voltage.

M13circuit breaker can be mounted vertically (upright) or horizontally (transverse).

M13MCCB is suitable for isolation and the symbol is " ".

M13MCCB meets the standard: GB14048.2 "low-voltage switchgear and control equipment, Part 2: circuit breakers."


Model and meaning


Note:

According to the pole, it classifies four types:

Type A: N-pole without over-current release components, and N-pole has been connected all along, and does not act with other three poles to turn on or off;

B-type: N-pole without over-current release components, and N-pole could act with other three poles (N-pole turn-on prior to turn-off);

Type C: N-pole fixed with over-current release components, and N-pole could act with other three poles (N-pole turn-on prior to turn-off);

D-type: N-pole fixed with over-current release components, and N-pole has been connected all along, and does not act with other three poles to turn on or off.

Circuit breaker for distribution without code, circuit breaker for motor protection with 2

No code for direct operation with handle; P for electric operation; Z for turning handle.


Classification according to rated current of over-current release:

M13-63 MCCB has nine: 6,10,16,20,25,32,40,50,63 A;

M13-100 MCCB has nine: 16,20,25,32,40,50,63,80,100 A;

M13-225 MCCB has seven: 100,125,140,160,180,200,225 A;

M13-400 MCCB has five: 225,250,315,350,400 A;

M13-630 MCCB has three: 400,500,630 A;

M13-800 MCCB has three: 630,700,800A;

M13-1250 MCCB has three: 800,1000,1250A.

Note: 6A only has electromagnetic (instantaneous) type, is not recommended specifications.

According to the wiring method: wiring in front of board, wiring on back of board, insertion type of the board.

According to over-current release pattern: thermodynamic-electromagnetic (double) type, electromagnetic (instantaneous) type.

According to the outfit, it has two types: with or without outfit.

The outfit include inner accessories and outside accessories: The inner accessories have shunt release, under-voltage release, auxiliary contact and alarm contact. The outside accessories are turning handle operation mechanism, power-driven operation mechanism and so on.

According to the breaking capacity: L-standard breaking type; M-second high breaking type; H-high breaking type


Normal operating conditions

■ Ambient air temperature: -5℃~+40℃, and average temperature in 24h is below +35℃.

■ Altitude: The altitude of the installation site is not more than 2000m.

■ Atmospheric conditions: The air relative humidity in the highest temperature +40℃ is not more than 50%; In the low temperature can have higher relative humidity. The maximum average relative humidity is 90%, while the average monthly minimum temperature is +25℃, and consider the temperature changes in product on the surface of the gel.

Accessories of circuit breakers

1.Internal accessory of circuit breakers

1.1 Shunt release

Rated control supply voltage of the shunt release: AC50Hz, 230V, 400; DC110V, 220V, 24V; When between 70%~110%, can break the circuit breaker reliably.

When rated control supply voltage of the shunt release is DC24V, the maximum length of copper wire should meet the following requirements

If the requirements of the above table are not met, it is recommended to design the shunt release control circuit using the following figure


1.2 Under-voltage release

When the power supply voltage drops to under-voltage release rated voltage of 70% to 35% of the range, the under-voltage release circuit breaker reliable break; when the supply voltage is below the rated voltage undervoltage release 35% , Under-voltage release to prevent the circuit breaker is closed; when the supply voltage is higher than 85% of the rated voltage of the under-voltage release, the under-voltage release ensures that the circuit breaker is closed. The undervoltage releases are rated at AC50Hz, 230V, 400V.

Special Note: The circuit breaker with undervoltage release, only in the under-voltage with rated voltage, which can open and close normally.


1.3 Pre-paid meter dedicated release

The rated operating voltage Ue of the pre-paid meter dedicated release is AC230/50Hz, it can worknormally in the range of (65% ~ 110%) Ue. When the Ctrl is cut off, the circuit breaker will delay 0.5s ~ 2s to be opening.Wiring diagram of pre-paid meter dedicated release
