SWM1 Molded Case Circuit Breaker

SWM1 moulded case circuit breaker with rated insulation voltage 800V, applied in the power system of AC50(60)Hz, rated voltage 690V and below, rated current 1250A and below as the transfer not frequently. The circuit breaker has the protection devices of over load, short circuit and under voltage ,it can protect the circuit and power equipment from broken.

The mccb can be sorted to C type (basic),L type (standard),M type (high breaking), H type(higher breaking) according to its rated limit short circuit breaking capacity.

The mccb has the features small volume, breaking capacity high, electric arcing short ,anti-vibration. It is the ideal product for application in land and ship.

The installation can be vertical or level and the standard conforms to IEC60947-2 and GB14048.2.

Working Temperature: -5℃ to +40℃
Utilization Category: A

Q1: What is the difference between SWM1 and standard MCBs?

Answer: The SWM1 Molded Case Circuit Breaker (MCCB) is designed for higher current capacities (up to 800A) and higher breaking capacities (up to 70kA) compared to Miniature Circuit Breakers (MCBs). It is typically used for main circuit protection in industrial and commercial switchboards.

Q2: Does the SWM1 series support motor protection?

Answer: Yes. The SWM1 series includes specialized versions for motor protection. These are calibrated to handle the high inrush currents typical of motor starting while providing reliable thermal-magnetic protection against overloads and short circuits.

Q3: What are the available pole configurations for SWM1 MCCBs?

Answer: The SWM1 series is available in 3-pole (3P) and 4-pole (4P) configurations. The 4P version is ideal for systems requiring a neutral disconnection for enhanced safety and grounding management.

Q4: Can I install SWM1 MCCBs horizontally?

Answer: Yes, the SWM1 is designed for flexible installation. It can be mounted vertically or horizontally without affecting its tripping characteristics, making it suitable for compact distribution boards.

Q5: Is the SWM1 compliant with international safety standards?

Answer: Absolutely. The SWM1 is fully compliant with the IEC 60947-2 international standard. It has passed rigorous testing to obtain CE, CB, and CCC certifications, ensuring its reliability in global engineering projects.
