Compact Motor Starter

MANUAL MAGNETIC Motor Starter-

The PumpBiz 66-2162A Manual Magnetic Motor Starter (MPW18-3-U016, see chart below) comes in an IP66 watertight enclosure (NEMA 4X), making it ideal for harsh environments. Designed for manual start/stop control of single-phase motors such as sump pumps and transfer pumps, this unit combines compact design with reliable protection.

The WEG MPW Series Manual Motor Protectors provide a complete solution for motor control applications. According to NEC standards, a combination motor starter must provide four key functions:

1. Motor Disconnect
2. Branch Circuit Protection
3. Motor Controller
4. Motor Overload Protection

The WEG MPW meets all of these requirements and complies with UL standards for Self-Protected Motor Controllers in Type-E and Type-F applications.

Standard Features:

• High short-circuit interrupting ratings – up to 50kA @ 480V
• Phase-loss sensitivity protection
• UL Type-E self-protected combination starter
• Suitable for motor disconnect applications
• Adjustable thermal overload protection with reset – includes ambient temperature compensation
• Corrosion-resistant PVC enclosure with two cable entry knockouts (top and bottom)
• Rated for DC applications

Protection of electric circuits + operation and protection of motors

The MPW Motor-protective Circuit-breakers are a compact solution for the protection of electric circuits, and operation and protection of motors up to 10HP (460V). With high breaking capacity, thus allowing the installation in specific applications with high short-circuit current. They assure complete protection for electric circuits and motors through thermal and magnetic releases, where the thermal protection may be set to protect against overloads and is equipped with a differential mechanism with phase-loss sensitivity, and the magnetic protection is set at 13xIn for short-circuit protection.

ON-OFF through pushbuttons (MPW18) have trip indication, which allows the operator to visualize the status of the breaker.
