KAL362251021 - 225 Amp Circuit Breaker

Introducing the KAL362251021 circuit breaker, a heavy-duty 3-pole thermal magnetic molded-case breaker built for reliable protection in demanding electrical systems. With a 225 A rating and an interrupting capacity of up to 42 kA at 240 V, this breaker delivers dependable fault interruption where safety and stability matter most. It includes an integrated 120 VAC shunt and both line/load lugs to simplify integration into existing installations—all while helping reduce downtime and maintenance.

Key Features and Benefits

• Thermal + Magnetic Protection: Offers both overload and short-circuit protection, so your system is safeguarded across a wide fault range.
• Integrated 120 VAC Shunt: Allows remote tripping or control without extra accessories, giving you greater flexibility in system design.
• Line and Load Lugs Included: Straightforward installation means less labor, fewer compatibility worries, and faster deployment.
• Molded Case Construction: Tough outer shell resists impact, moisture, and industrial wear, ideal for harsh environments.
• High Interrupting Capacity: Handles up to 25 kA at 480 V or 22 kA at 600 V (and 42 kA at 240 V) to tackle major fault events safely.
• Consistent Performance Under Load: Maintains reliability even with frequent cycling or heavy-duty use.

Each feature translates into tangible benefits: less risk of system outages, simpler control options, quicker installation, and long-term peace of mind.
