Ls BK63H - 20A, 240VAC, 3-Pole, Circuit Breaker

Introducing the LS BK63H 20A, 240VAC, 3-Pole Circuit Breaker — a trusted safeguard for three-phase electrical systems. With a 20-amp rating and 240-volt capability, this breaker provides reliable overcurrent protection where it matters most: panelboards, switchboards, and control panels in industrial, commercial, and OEM setups.

Built for the demands of modern distribution and motor control centers, the BK63H's 3-Pole design ensures all three phases trip together, preventing uneven phase protection and reducing equipment risk. This means safer operation, easier panel wiring, and quicker fault isolation.

Key specifications

• Current rating: 20A
• Voltage rating: 240VAC
• Poles: 3-Pole
• Breaker type: Circuit Breaker

Why it matters

In busy electrical environments, dependable overcurrent protection is essential. The LS BK63H helps protect motors, drives, and other three-phase equipment from overloads and short circuits, safeguarding wiring, control circuits, and connected loads. Its 3-pole configuration simplifies wiring and ensures balanced protection across all phases, which can improve system reliability and reduce the risk of nuisance trips from single-phase faults.

Ideal applications

• Industrial panelboards and switchboards requiring three-phase protection
• Motor control centers and machine control panels
• Commercial electrical distribution where compact, reliable protection is needed
• OEM equipment that requires standardized, scalable overcurrent protection

Practical tips

Install BK63H in accordance with electrical codes and panel design best practices. Use it to create clear separation between power and control circuits in your distribution panels. Regularly verify torque on terminals and replace after any fault event to restore optimal protection. For OEM setups, ensure the breaker rating aligns with the connected motor or load to maintain coordinated protection across your system.
