Siemens B245H00S01 45A 2-Pole 240 V Circuit Breaker

Siemens B245H00S01 stands as a robust 45 Amp, 2-pole, 240 V circuit breaker designed to guard your 240-volt electrical circuits. As a Siemens‑manufactured component, it brings precise trip characteristics and dependable performance to residential and light commercial breaker panels.

• Current rating: 45 A
• Poles: 2
• Voltage rating: 240 V
• Part number: B245H00S01
• Manufacturer: Siemens
• Application: 2-pole breaker for protecting 240 V circuits

Why this matters: a 2-pole design protects both hot legs of a 240 V circuit, delivering reliable overcurrent protection for high‑draw appliances and equipment. The 45 A rating provides a balanced choice for circuits that require more amperage without compromising conductor safety, helping prevent overheating and potential faults.

Ideal use cases:

• Protect 240 V circuits powering large appliances (such as air conditioning units and water heaters) or other high‑draw equipment.
• Replacement part for Siemens panels that require a B245H00S01 or compatible 2-pole breaker.
• On-hand stocking for routine electrical maintenance in homes or light commercial environments.

Installation and compatibility notes: Designed for Siemens panels that accept this breaker style. For proper performance and safety, verify panel compatibility with your specific model and refer to professional electrical guidance if needed.
