Siemens 5SP4180-7 Molded Case Circuit Breaker

Siem­ens 5SP4180-7 is a SENTRON single‑pole molded‑case circuit protector rated for 80 A and designed for 230/400 V AC mains, delivering up to 10 kA short‑circuit interrupting capacity. This thermal‑magnetic device uses a Curve C trip characteristic to respond to both overloads and short circuits, providing long‑time and instantaneous protection for a single live conductor in compact panel layouts. With a 70 mm depth, it is sized for space‑constrained installations and is UL1077‑listed for use as a supplementary protector in residential or light commercial electrical systems. Part of Siemens’ 5SP family, the 5SP4180‑7 is commonly employed to protect feeders and branch circuits that require reliable, precise overcurrent protection in a compact form factor.
