FAQs
The MPSC163WEAXXSW uses a drawout vertical mounting style and a standard-frame configuration, which simplifies installation in existing switchgear and panelboards. This design allows quick cartridge-like replacement during preventive maintenance and enables easier alignment with adjacent modules in space-constrained enclosures, reducing commissioning time and field labor costs.
The MPSC163WEAXXSW is a three-pole device rated for 1600 A with a 100 kA short-circuit interrupting capacity. It is designed for drawout installation and does not include an internal trip unit, meaning coordination with external protection relays or trip units must be planned during panel design and commissioning.
Yes. This model carries CE Marked and UL Listed certifications, along with NEMA compliance. These certifications support European and North American safety and performance requirements, enabling broad deployment across multinational facilities and helping meet regulatory procurement standards.
Recommended for high-current feeder protection in panelboards and motor control centers, particularly where a rugged standard-frame breaker is needed and external protection coordination is planned. It is well-suited for industrial distributions, batch processing lines, and renewable or chemical processing facilities that require reliable protection with straightforward maintenance.
Consider total cost of ownership including reduced downtime from robust interrupting capability, simplified maintenance due to drawout mounting, and lower field complexity from using an external protection scheme rather than an internal trip unit. Availability of spare parts and established certifications further support predictable maintenance cycles and long-term reliability.
