What is ul489?
UL 489 circuit breakers are “intended for installation in a circuit breaker enclosure or as parts of other devices, such as service entrance equipment and panelboards.” They are regularly required on panel designs, per the National Electrical Code.
What is drawout switchgear?
Low-voltage switchgear is a metal-enclosed assembly with three-position, draw-out power circuit breakers engineered to monitor and protect low-voltage electrical systems.
What is series rated?
Series rated is a combination of circuit breakers or fuses and circuit breakers that can be applied at available short-circuit levels above the interrupting rating of the load side (protected) circuit breaker, but not above the interrupting rating of the main or line-side device.
Where are Eaton circuit breakers made?

What is MCCB circuit breaker?
A moulded case circuit breaker (MCCB) is a type of electrical protection device that is used to protect the electrical circuit from excessive current, which can cause overload or short circuit.
What UL 1558?
UL 1558 – Standard for Metal-Enclosed Low-Voltage Power Circuit Breaker Switchgear defines safety tests for switchgear assemblies that service circuits operating at nominal ac voltages of not more than 1,000 volts. UL 1558 testing evaluates switchgear that is designed in accordance with ANSI C37.
What is medium voltage switchgear?
Eaton’s medium-voltage switchgear provides centralized control and protection of medium-voltage power equipment and circuits in industrial, commercial, and utility installations involving generators, motors, feeder circuits, and transmission and distribution lines.
What is a AIC rating?
AIC: Ampere Interrupting Capacity The AIC rating indicates the maximum available fault current (in amps) that an overcurrent protection device (circuit breaker, fuse, etc.) will safely clear when a fault is applied at the load side of the overcurrent protection device.
What is Series rating panelboard?
Series rating is the combination of two or more OCPDs (over current protective devices) connected in series where the interrupting current rating of the downstream device/s is less than the interrupting current rating of the system.
