MA3800 - 800 Amp Circuit Breaker

MA3800 - 800 Amp Circuit Breaker

When you're matching a breaker for existing electrical equipment, the small details matter just as much as the amp rating. The MA3800 is an 800-amp, 3-pole MA thermal-magnetic circuit breaker with an interchangeable trip unit and load-side terminals. When the MA type, 800A rating, three-pole configuration, trip-unit style, A.I.C. ratings, terminals, and dimensions match the application, the MA3800 can be considered a form, fit, and functional replacement candidate. Its solid construction is built to last when selected, installed, and maintained correctly.

Key Features and Benefits

• 800 Amp, 3-Pole Configuration: Clearly defined electrical ratings make it easier to determine whether the MA3800 matches an existing application.
• Thermal-Magnetic Circuit Breaker: Uses the specified thermal-magnetic configuration for applications requiring this breaker type.
• Interchangeable Trip Unit: An important feature to confirm when replacing an existing MA breaker with the same trip-unit configuration.
• Load-Side Terminals Included: The supplied product information specifies that load-side terminals are included.
• 40°C Rated: Provides another specific operating detail to compare with the requirements of the existing electrical equipment.

Material Compliance and Certifications

The supplied specifications for the MA3800 did not include specific agency certifications, electrical listings, or material-compliance information. Therefore, do not assume UL, IEC, RoHS, REACH, or other certification and compliance status.

Where a particular certification or material standard is required, confirm the applicable breaker markings and supporting technical documentation before installation.

Where It Works Best

The MA3800 800 amp circuit breaker is best suited to existing electrical equipment that specifically calls for an MA-type, 3-pole, 800A thermal magnetic circuit breaker with an interchangeable trip unit. That makes it particularly relevant when maintaining legacy electrical equipment, and the objective is to match the required form, fit, and electrical function rather than change the equipment configuration.
