Siemens E2N1S - 100 A, 600 V, 2-Pole Circuit Breaker | AmpState

Siemens E2N1S is a 2-pole molded-case circuit breaker engineered to protect branch circuits in panelboards and load centers. With a 100 A rating and a 600 V maximum, it delivers dependable overcurrent and short-circuit protection where reliability matters most.

• Compact molded-case design optimizes panel space, making it easier to route conductors and leave room for future expansions.
• Thermal-magnetic trip unit provides stable, repeatable protection: the thermal element handles sustained overloads, while the magnetic element delivers fast response to short circuits.
• 2-pole configuration protects two conductors in a single device, suitable for typical panelboard and loadcenter setups.
• OEM-compatible designed to pair with matching Siemens OEM load centers and panelboards for a seamless, uniform protection system.
• Versatile applications ideal for residential, commercial, and light industrial environments requiring reliable branch-circuit protection.

Why it matters: choosing the E2N1S helps you consolidate protection in a compact footprint without sacrificing safety or performance. The combination of space efficiency and a robust thermal-magnetic trip means predictable behavior across a range of loads and switching events, reducing downtime and simplifying maintenance in busy electrical rooms.
