MA3250 - 250 Amp Circuit Breaker

MA3250 - 250 Amp Circuit Breaker

The MA3250 is a 250-amp, three-pole MA thermal magnetic circuit breaker designed for electrical applications that require matching the existing breaker's specifications and physical setup. It has an interchangeable trip unit, is rated at 40°C, and includes load-side terminals. Instead of relying solely on the part number, purchasers can use these electrical and dimensional specifications to determine whether your breaker matches the equipment already in service.

Key Features and Benefits

• The 250A rating ensures the specified 250-amp rating is available for use with compatible electrical applications.
• The three-pole design gives technicians a key specification to compare with the existing breaker and equipment.
• The device is MA type, which means technicians can easily verify it during replacement work.
• The thermal-magnetic operation uses the specified thermal-magnetic circuit breaker configuration.
• The interchangeable trip unit is a crucial feature when verifying compatibility with an existing installation.
• The specified configuration includes the load-side terminals.
