NEB2B025B - 25 Amp Circuit Breaker

NEB2B025B - 25 Amp Circuit Breaker

The Siemens NEB2B025B circuit breaker is built to deliver dependable, adequate electrical protection for your low‑voltage panelboards — whether in commercial or industrial setups. This EG‑frame breaker is fitted with a thermal‑magnetic trip unit that keeps overcurrent events in check, helping prevent overloads and short circuits before they can cause damage. Designed to handle hefty loads, it’s a solid choice when you need consistent performance and peace of mind under demanding conditions. Rated at 25 amps, this two‑pole unit offers high interrupting capacities: 22 kAIC at 600Y/347V and 35 kAIC at 480V — in other words, it’s ready to stand up to high‑fault situations without compromise.

Key Features and Benefits

• Thermal‑Magnetic Trip Unit: Delivers dependable overcurrent protection to safeguard wiring and equipment when overloads or short circuits occur.
• High Interrupting Capacity: With 22 kAIC at 600Y/347V and 35 kAIC at 480V, the breaker handles severe fault conditions confidently, reducing the risk of damage or downtime.
• Two‑Pole, 25 Amp Rating: Offers straightforward, stable protection for 25A circuits, suitable for many commercial and industrial electrical applications.
