NEB2B015B - 15 Amp Circuit Breaker

NEB2B015B - 15 Amp Circuit Breaker

The Siemens NEB2B015B gives you dependable, compact protection for panelboard electrical systems. Designed for low‑voltage, two‑pole installations, this breaker delivers precise overload and short‑circuit response through a built-in thermal‑magnetic trip unit. With a 15 amp current rating and high interrupting capacity — 22 kAIC at 600Y/347 V and 35 kAIC at 480 V — this breaker fits a wide variety of residential and light commercial panelboard applications. Its modest footprint and secure mounting make it an easy choice when space is limited but protection cannot be compromised. Whether you’re wiring a new panel or replacing an existing breaker, the NEB2B015B brings solid performance with minimal fuss.

Key Features and Benefits

• Thermal‑Magnetic Trip Mechanism: Combines slow thermal response and fast magnetic action to guard against overloads and short-circuits — ideal for mixed-load environments.
• High Interrupting Capacity: Rated at 22 kAIC (600Y/347 V) and 35 kAIC (480 V), giving you reliable protection even under heavy fault conditions.
• Two‑Pole, 15 Amp Rating: Perfect for controlling 240 V circuits or dual-phase loads with dependable performance.
• Flexible Wiring Support: Equipped with load-side lugs that accept 8 to 1/0 AWG (copper or aluminum), allowing for a variety of wiring setups and easy panel retrofits.
• Compact, Panelboard‑Ready Design: Its small dimensions and easy mounting make installation quick and clean — ideal when space inside the panel is limited.
