( Brand: Ferraz-shawmut ), ( Manufacturer Part Number: MPDB67461 )
The Ferraz-Shawmut MPDB67461 Mersen PDB 380A 1-pole hole 500-4 2-14 is a circuit breaker designed for use in industrial and commercial electrical applications. This breaker is manufactured by Ferraz-Shawmut, a leading provider of electrical power distribution equipment.
The Mersen PDB 380A 1-pole hole 500-4 2-14 is specifically designed to meet the requirements of NEMA MG-2 Standard for Industrial Control and Motor Circuits. It is a 1-pole breaker, which means it is designed to control the flow of current to a single circuit. The breaker is rated for a continuous current of 500 Amps and a maximum interrupting current of 4,000 Amps.
The breaker features a Mersen Type 380A frame, which is designed to provide superior protection against short-circuit currents. The breaker also includes a trip unit with a 2-14 time-delay setting. This allows the breaker to delay its tripping action for a specific period of time after the current surge, which can help prevent nuisance tripping and reduce the load on the electrical system.
The breaker is designed with a copper bussing system, which provides excellent conductivity and durability. The breaker also includes a mechanical trip mechanism, which provides reliable and accurate tripping action. The breaker is suitable for use in industrial and commercial electrical systems where high currents are required.
The Ferraz-Shawmut MPDB67461 Mersen PDB 380A 1-pole hole 500-4 2-14 is a high-quality circuit breaker designed to provide reliable protection against electrical overloads and short-circuits in industrial and commercial electrical applications. Its advanced features, including the Mersen Type 380A frame and the 2-14 time-delay setting, make it an excellent choice for applications where precise control over electrical current is essential.
The Ferraz-Shawmut MPDB67461 and MERSEN PDB 380A 1-pole holes are circuit breaker distributor boxes used in electrical systems. Both products have their unique features, advantages, and disadvantages.
Ferraz-Shawmut MPDB67461: Pros:1. UL and CSA listed, ensuring safety and compliance with North American electrical codes.
2. Suitable for installations with 500-4 kVA transformers.
3. Designed for use with Type B and Type C circuit breakers.
4. Features a compact design for easy installation.
5. Made of die-cast aluminum, providing durability and resistance to corrosion.
Cons:1. Limited compatibility with specific circuit breaker types and transformer ratings.
2. Higher price point compared to some other options on the market.
MERSEN PDB 380A 1-pole holes: Pros:1. UL and CSA listed, ensuring safety and compliance with North American electrical codes.
2. Suitable for installations with 380A current ratings.
3. Designed for use with various types of circuit breakers, including molded case, insulated case, and low voltage.
4. Lightweight and easy to install due to its plastic construction.
5. Offers a lower price point compared to some other options on the market.
Cons:1. Not suitable for use with transformers larger than those rated for 380A.
2. The plastic construction may not provide the same level of durability and resistance to corrosion as metal options.
Conclusion:Both the Ferraz-Shawmut MPDB67461 and MERSEN PDB 380A 1-pole holes are reliable options for electrical system applications. The choice between the two primarily depends on the specific transformer rating and circuit breaker type requirements of the project.
If the project involves a 500-4 kVA transformer and Type B or C circuit breakers, the Ferraz-Shawmut MPDB67461 would be the better choice due to its compatibility and durability. However, if the project involves a 380A current rating and various circuit breaker types, the MERSEN PDB 380A 1-pole holes would be a more cost-effective solution.
Recommendation:Based on the given information, I would recommend the Ferraz-Shawmut MPDB67461 for projects requiring a 500-4 kVA transformer and Type B or C circuit breakers, and the MERSEN PDB 380A 1-pole holes for projects involving a 380A current rating and various circuit breaker types. Always ensure that the selected distributor box complies with local electrical codes and regulations.
