Siemens ED42B025 - 25 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Siemens ED42B025 is a 25A, 480V, two-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built to endure demanding installations, it combines robust hardware with precise protection to keep electrical systems safe and reliable. Secure, vibration-resistant installation - Bolt-on mounting provides a rigid bus connection, reducing loosening and movement in busy electrical environments. This means fewer service calls and steadier performance in commercial spaces, multi-metered panels, and industrial setups. Stable, responsive protection - Thermal-magnetic trip unit delivers repeatable protection by combining a thermal element for sustained overloads with an instantaneous magnetic trip for rapid response to short circuits. This dual-action protection helps prevent damage to wiring and connected equipment while minimizing nuisance trips. Designed for compatibility and versatility - Compatibility with matching OEM Siemens load centers and panelboards simplifies replacement and upgrades, ensuring seamless integration into existing Siemens installations. - Suitable for residential, commercial, and light industrial applications, making it a versatile choice for a range of panel configurations and electrical demands. What makes it stand out - Two-pole design ensures simultaneous disconnection of both hot lines, maintaining proper line-to-line protection for 480V circuits. - Molded case construction delivers durable insulation and reliable performance in environments subject to vibration, temperature swings, and routine maintenance. - The ED42B025 is a purpose-built solution from Siemens, engineered to work as part of a coherent protection strategy across Siemens panelboards and accessories. Use cases and practical scenarios - Upgrading an aging panel to provide reliable 25A protection for a dedicated 480V circuit in a light commercial setting. - Replacing a failed breaker in a Siemens load center or panelboard with a compatible bolt-on unit to restore circuit protection without compatibility concerns. - Expanding a panel’s capacity for new equipment in a workshop or small manufacturing space, while maintaining consistent protection characteristics.
