Square D EJB24025 - 25 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

The Square D EJB24025 is a 25A, 480V, 2-pole bolt-on molded case circuit breaker designed to safeguard branch circuits in panelboards and load centers. Built for dependable overcurrent and short-circuit protection, it combines rugged construction with precise operating performance to keep electrical systems running smoothly.

Key advantages that set it apart

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, minimizing loose contacts in environments subject to movement or vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection by pairing a thermal element for gradual overload response with a magnetic mechanism for rapid short-circuit isolation.
• OEM-compatible design ensures reliable fit and performance with matching Square D load centers and panelboards.
• Versatile installation suitable for residential, commercial, and light industrial applications where 480V two-pole protection is required.
