Industrial CHB345 45A 3-Pole 240 V Circuit Breaker Potential Transformer

Industrial CHB345 45A 3-Pole 240 V Circuit Breaker is engineered for demanding power environments, delivering dependable overcurrent protection for three-phase systems. With a 45 A rating and a 240 V operating range, this part (Part Number CHB345) helps keep motors, pumps, and control circuits safe from faults and surges.

Key specifications

• Current rating: 45 A
• Poles: 3
• Voltage rating: 240 V
• Part Number: CHB345

In industrial settings, protecting three-phase equipment matters. The CHB345 disconnects all live conductors quickly when fault current exceeds the rating, preventing damage to motors, controllers, and wiring and helping reduce costly downtime. Its 240 V rating aligns with common plant distributions, making it a practical fit for a wide range of manufacturing environments.

Ideal applications

• Motor control centers and drives in manufacturing lines
• Conveyor systems, pumps, and fans in processing facilities
• Industrial automation panels requiring reliable three-phase protection
• Replacement part for existing CHB345 installations

Practical guidance

• Pair with protection schemes that utilize potential transformers for monitoring and metering in larger plant environments.
• Regularly inspect connection points and ensure proper torque according to your panel standards.
• Keep spare CHB345 units on hand to support proactive maintenance and fast replacements.

Choose the CHB345 for a dependable, clearly defined three-pole, 240 V circuit protection solution that keeps industrial processes safe and productive.
