KC34200 - 200 Amp Circuit Breaker

KC34200 - 200 Amp Circuit Breaker

The KC34200 200A Circuit Breaker is engineered to deliver dependable, high-capacity circuit protection for commercial or industrial environments. Combining thermal-magnetic protection with a molded-case housing, this 3-pole breaker provides both overload and short-circuit defense in one compact unit. With interrupting ratings of 65 kA at 480 VAC and 100 kA at 240 VAC, the KC34200 is built to safeguard even high-demand systems with confidence.

Key Features and Benefits

• High interrupting rating: 65 kA @ 480 VAC and 100 kA @ 240 VAC ensures the breaker can safely interrupt fault currents in demanding systems.
• Thermal-magnetic protection: combines heat-based overload trip with magnetic short-circuit trip for fast, reliable response.
• Molded-case construction: durable and built to resist wear, impact, and environmental stresses.
