Siemens ED63A001 - 1 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Siemens ED63A001 is a compact yet robust 1 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to deliver reliable branch-circuit protection in panelboards and load centers. Built for environments where vibration or movement is a factor, the secure bolt-on mounting creates a rigid, low-impedance bus connection that helps minimize arcing and ensure consistent protection performance over time.

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection that stays put through office, workshop, or field conditions.
• Thermal-magnetic trip unit combines slow, thermal overload protection with instantaneous magnetic response for stable, repeatable protection across varying loads and startup surges.
• 3-pole configuration provides comprehensive protection across all conductors in 3-phase systems, making it suitable for modern commercial and light industrial panel setups.
• OEM-compatible design engineered to pair with matching Siemens OEM load centers and panelboards, simplifying replacements and future upgrades.
• Versatile application ideal for residential, commercial, and light industrial environments where precise low-amperage protection is required on branch circuits.
