Product Overview
D-Curve MCCB Circuit Breaker for Power Distribution - 400 Amp - Three Pole - 480V AC Max - Fixed Thermal Fixed Magnetic Trip - NEMA 3R Enclosure is a product intended for professional commercial and industrial applications.
Key Specifications
- Trip Curves: Circuit breakers are classified according to their trip curves. A trip curve is a representation of how a circuit breaker is expected to behave. In other words, a trip curve specifies when a circuit breaker should activate during overcurrents and short circuits. In order to avoid nuisance tripping, circuit breakers need different trip curves to account for variances in the balance between adequate overcurrent protection and optimal machine performance.
- UL 489 vs UL 1077: Circuit breakers will typically be rated either UL 489 or UL 1077. There is a distinct difference between these two ratings and the scenarios in which they should be used. Circuit breakers that are rated UL 489 can be used for branch circuit protection and for providing protection for service, feeder, and branch circuit equipment. UL 489 devices are usually used on main panels, panelboards, control panels, motor control panels, and switchboards.
- Enclosure: The weatherproof enclosure of the MPD-XX-CB-489-480V-3P-400A-D-N3R is made from code gauge low carbon steel and features a NEMA Type 3R rating which means that it is intended for outdoor use. It provides a degree of protection against rain, sleet, and snow as well as damage from external ice formation. This enclosure also features external mounting brackets, a continuous hinge, a padlockable pull down hasp, and an ANSI 61 light gray powder coated finish.
- Mounting: The MPD-XX-CB-489-480V-3P-400A-D-N3R is equipped with external mounting brackets.
This item is grouped with Power Distribution Accessories and Replacement Parts.
Before ordering: Verify ratings, dimensions, compatibility, and installation requirements before ordering.
