PJA36080CU44A - 800Amp Circuit Breaker

PJA36080CU44A - 800Amp Circuit Breaker

The PJA36080CU44A is an 800-amp, 3-pole PJA circuit breaker for commercial and industrial electrical distribution applications. It is rated at 65 kA at 480 VAC and uses a MicroLogic 6.0 A electronic trip unit with LSIG protection. LSIG covers Long-Time, Short-Time, Instantaneous, and Ground-Fault protection, giving the breaker several ways to respond to overload and fault conditions. This model also has a 100% continuous current rating, which is important when you're working with a system designed for continuous loading. The breaker measures 12.86 inches high, 8.27 inches wide, and 8.05 inches deep. If you're replacing an existing PJA breaker, it's worth checking every specification rather than simply matching the 800A rating. The full PJA36080CU44A part number, number of poles, interrupting rating, trip unit, dimensions, and equipment requirements all matter when determining whether this is the right breaker for the application.

Key Features and Benefits

• 800-amp rating for higher-current electrical distribution applications.
• 3 poles for use in compatible three-phase systems.
• 65kA interrupting rating at 480VAC for applications requiring this level of fault-current interruption.
• MicroLogic 6.0 A electronic trip unit provides adjustable electronic protection functions.
• LSIG protection includes Long-Time, Short-Time, Instantaneous, and Ground-Fault functions.
• 100% continuous current rating for applications designed around the breaker's full continuous-current capability, when installed according to applicable requirements.
• PJA configuration for compatible electrical distribution equipment.

Material Compliance and Certifications

• For compliance information, refer to the applicable manufacturer documentation for the PJA36080CU44A and confirm the requirements of the equipment in which the breaker will be installed. Certifications, listings, electrical ratings, and installation requirements should be checked before putting any replacement circuit breaker into service.
• It's also important to verify the available fault current, system voltage, conductor requirements, and applicable electrical codes. Installation and service should be performed by qualified electrical personnel.

Where It Works Best

• The PJA36080CU44A makes sense in commercial and industrial electrical systems that specifically call for an 800A, 3-pole PJA breaker with LSIG protection. Typical settings may include larger commercial properties, manufacturing facilities, institutional buildings, and other three-phase power distribution applications.
• The MicroLogic 6.0 A trip unit is a particularly useful part of this model. Instead of providing only basic overcurrent protection, it incorporates Long-Time, Short-Time, Instantaneous, and Ground-Fault functions. For a system that requires those protection characteristics along with an 800A rating, that's an important distinction.
