Product description
Shipping
Siemens JXD63H400L is a 400A, 600V, 3-pole molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers.
What makes it stand out
- Compact molded-case design maximizes panel space and simplifies layouts in both new installations and upgrades.
- Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element handles sustained overloads while the magnetic element quickly responds to high-magnitude faults, reducing nuisance trips and wear on wiring.
- OEM-compatible fit engineered to work with matching Siemens OEM load centers and panelboards, ensuring reliable mounting, optimal contact performance, and warranty alignment.
- Three-pole configuration ideal for 3-phase systems, providing comprehensive protection for feeders and main disconnects in commercial and light industrial settings.
- 600V rating appropriate for a range of commercial, light-industrial, and select residential applications requiring higher-voltage protection.
