Siemens ED23B025 - 25 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens ED23B025 is a 25A, 240V, 3-pole bolt-on molded case circuit breaker purpose-built to protect panelboards and load centers from overcurrent and short circuits. Its robust bolt-on mounting creates a rigid, vibration-resistant bus connection, so you’re less likely to experience loose connections or intermittent trips in demanding environments. The thermal-magnetic trip unit combines precise overload protection with fast magnetic tripping on a short circuit, delivering stable, repeatable performance when it matters most. Why this breaker stands out

• Secure bolt-on mounting: engineered for a solid, vibration-resistant connection that stands up to real-world panel installations.
• Thermal-magnetic protection: dependable response to both sustained overloads and instantaneous short circuits, helping minimize equipment damage.
• OEM-compatible design: designed to work seamlessly with matching Siemens OEM load centers and panelboards, simplifying replacements and upgrades.
• Versatile 3-pole configuration: ideal for three-phase systems and multi-pole protection across residential, commercial, and light industrial applications.

Practical applications and use cases

• Upgrade or replace aging breakers in Siemens panelboards to restore reliable overcurrent and short-circuit protection.
• Install in new or existing 3-pole distribution circuits within residential complexes, commercial offices, or light industrial facilities.
• Use in panelboards where a secure bolt-on fit and dependable thermal-magnetic trip performance are critical for steady operation.
• Maintain system safety in environments where vibration or equipment start-up stresses require a rugged mounting solution.
