Eaton - Cutler Hammer - GLS4400AAG MOULDED CASE CIRCUIT BREAKER (MCCB), 4 POLE, 400 AMP GL FRAMED, 50 KA BREAKING CAPACITY, G SERIE

Moulded Case Circuit Breaker (MCCB), 4 Pole, 400 Amp GL Frame, 50 kA breaking capacity, G Series

This 4 Pole, 400A, G Series Moulded Case Circuit Breaker from Eaton (MCCB) provides high-end performance in less space than standard circuit breakers or comparable fusible devices. Built-in ground fault protection down to 20 Amperes. Typical applications include machine tool control panels, motor control, panel boards, feeder pillars, switchgear, Bus Bar trunking tap-offs and more.

Circuit Breaker has a toggle handle operating mechanism, which also serves as a switching position indicator. The indicator shows the positions of: ON, OFF and TRIPPED. The toggle handle snaps into the TRIPPED position if the breaker encounters an overcurrent or short circuit. Before the MCCB can be reclosed following a trip, the toggle handle must be moved beyond the OFF position (RESET).

The contact assembly of this circuit breaker has a high-speed blow-open action when it encounters the electromechanical forces produced by high-level fault currents. For additional safety, the toggle handle is mechanically trip-free so that the contacts cannot be held closed against short circuit currents. Tripping due to overload or short circuits is indicated by the position on the handle.

The GLS4400AAG MCCB is current limiting because of its high repulsion contact arrangement and incorporation of state-of-the-art arc extinguishing technology. Eaton Series G Circuit Breakers meet applicable UL 489 and IEC 60947-2 standards.
