SND69120ANT - 1200Amp Circuit Breaker

SND69120ANT - 1200Amp Circuit Breaker

The Siemens SND69120ANT is a SENTRON molded case circuit breaker for your compatible commercial and industrial electrical distribution equipment that requires a 1200A, 3-pole, 600V breaker with LSI electronic trip functions. Built on the Siemens ND frame, this standard 40°C breaker uses an electronic trip unit (ETU) with Sensitrip functions for long-time, short-time, and instantaneous protection. For maintenance teams working with existing electrical equipment, the catalog number, frame size, amperage, voltage, trip configuration, lug arrangement, and physical dimensions provide the information needed to evaluate form, fit, and functional compatibility.

Key Features and Benefits

• 1200A, 3-pole configuration: Designed for compatible three-phase electrical distribution equipment requiring a 1200-amp molded case circuit breaker.
• 600V rating: Suitable for applications designed around the breaker's specified voltage and interrupting ratings.
• LSI electronic trip functions: Provides long-time, short-time, and instantaneous protection functions.
• Sensitrip functions: Uses Siemens Sensitrip electronic trip technology for the specified LSI protection functions.
• ND frame construction: Maintains the physical frame configuration needed for compatible equipment designed around the Siemens ND frame.
• TA4N8500 lugs: Line- and load-side lugs support 250–500 kcmil copper or aluminum conductors.
