KAL361251021 - 125 Amp Circuit Breaker

KAL361251021 - 125 Amp Circuit Breaker

When you're tracking down a KAL361251021, the 120VAC shunt is one detail you don't want to overlook. This 125-amp, three-pole Type KAL molded-case circuit breaker combines the shunt configuration with thermal-magnetic protection, 60 Hz operation, and a 40°C rating. The KAL361251021 is built to last, but the key to selecting it is simple: make sure its ratings, shunt voltage, connections, Type KAL configuration, and dimensions align with the equipment already in place.

Key Features and Benefits

• 125A, 3-pole design: Makes it easy to compare the basic electrical configuration to that of the breaker being replaced.
• 120VAC shunt: A key identifying feature for installations requiring this specific shunt voltage.
• Type KAL configuration: Provides a clear reference point when sourcing a form-fit-and-function replacement for compatible equipment.
• Thermal-magnetic protection: Uses the specified thermal-magnetic trip design.
• Line and load lugs included: Both sides are supplied with lugs, removing any guesswork about the stated connection configuration.
• 60 Hz, 40°C rated: Two additional specifications that can be checked directly against existing system requirements.

Material Compliance and Certifications

Specific UL, CSA, IEC, RoHS, REACH, or other certification and material-compliance information was not provided for the KAL361251021. Those approvals should not be assumed from the product type or electrical ratings. If a particular standard or certification is required for the installation, confirm it for this exact part number.

Where It Works Best

The KAL361251021 is best suited for compatible existing and legacy electrical equipment that calls for a 125A, three-pole Type KAL molded-case circuit breaker with a 120VAC shunt. Its included line and load lugs, thermal-magnetic protection, interrupting ratings, and physical dimensions give you a solid checklist for determining whether it matches the existing installation.

Before installation, compare the complete specification—not just the 125A rating. Confirm the KAL361251021 part number, Type KAL configuration, three-pole arrangement, 120VAC shunt, A.I.C. ratings, 60 Hz frequency, 40°C rating, lug arrangement, and dimensions against the requirements of the equipment already in service.
