Siemens EQG660D - 60 A, 240 V Circuit Breaker | AmpState

The Siemens EQG660D is a 60A, 240V molded-case circuit breaker designed to deliver dependable branch-circuit protection in panelboards and load centers. Built to interrupt fault currents quickly and cleanly, it helps protect wiring, devices, and occupants by preventing electrical fires and equipment damage.

• Compact molded-case design maximizes panel space and simplifies installation, so you can fit more circuits without crowding the enclosure.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining a thermal element for overloads with a magnetic element for short circuits, reducing nuisance trips while safeguarding downstream conductors.
• OEM-compatible reliability engineered to be compatible with matching Siemens load centers and panelboards for a seamless fit, consistent performance, and easier service in the field.
• Versatile application suitable for residential, commercial, and light-industrial electrical systems, making it a practical choice for upgrades and new installations alike.

• Protection you can trust protects branch circuits from overcurrent and short-circuit conditions, helping prevent damage to wiring, outlets, and connected equipment.
• Consistent performance the thermal-magnetic design delivers predictable trip behavior across load variations and fault scenarios.
• Long-term reliability built to withstand typical panelboard environments, reducing the need for frequent replacements and maintenance.
