Description
PowerPact M-, P-, and R-frame and Compact NS630b–NS3200 electronic trip molded case circuit breakers are designed to protect electrical systems from damage caused by overloads, short circuits, and ground faults. All circuit breakers are designed to open and close a circuit by nonautomatic means and to open the circuit automatically on a predetermined overcurrent. Electronic trip molded case circuit breakers use an electronic trip system to signal the circuit breaker to open automatically. The PowerPact M-frame (800 A frame size), P-frame (1200 A frame size) and R-frame (3000 A frame size) circuit breakers are dual rated to UL489 and IEC 60947-2. The Compact NS630b–NS1600 (1600 A frame size) and NS1600b–NS3200 (3200 A frame) circuit breakers are rated to IEC 60947-2 only. M-frame molded case circuit breakers are equipped with a basic ET1.0 electronic trip system, which has a fixed long-time (overload) setting and an adjustable instantaneous (short-circuit) trip setting. P-frame, R-frame and NS630b–NS3200 molded case circuit breakers are available with either a basic ET 1.0I electronic trip system or with a more advanced Micrologic trip system. Electronic trip motor circuit protectors (trip system ET 1.0M), which trip on short circuit only, and automatic molded case switches, which trip at a predetermined self-protection level only, are also available for special applications. All of these circuit breakers are available labeled as Square D or Schneider Electric (formerly Merlin Gerin, Federal Pioneer, or Federal Pacific). This stacking connectors is for Compact breakers. This product is a communication accessory and is compatable with Compact & PowerPact devices. This product has a rated current of 0-630A and comes in a set of 10. This product comes with an 18 months warranty.
