PowerPact R-frame electronic trip circuit breakers are designed to protect electrical equipment from damage caused by overload, short circuit and ground fault. All circuit breakers are designed not to automatically turn a circuit off and on and to automatically open the circuit at a predetermined overcurrent. Electronic trip circuit breakers use an electronic trip system to signal automatic circuit breaker opening. PowerPact R-frame circuit breakers (3000A frame size) are dual rated to UL489 and IEC 60947-2. P-frame and R-frame circuit breakers are available with either a simple ET 1.0I electronic trip system or a more advanced Micrologic trip system. ET 1.0M electronic trip system that trips only on short circuit and automatic molded case circuit breakers that only trip at a predetermined self-protection level are also available for special applications. This PowerPact R circuit breaker has a current rating of 1600A and a rated operating current of 600V AC with a breaking capacity of 65kA@600V AC. This 3 pole switch is a panel mount switch and has a continuous current rating of 80%. This switch features electronic trip technology and an ET 1.0I trip. This product conforms to UL listings, CSA and IEC standards. The dimensions for this product are 419.9mm (H), 412.5mm (W), 368.0mm (WxHxD). This product comes with an 18 month warranty.
