Introduction to Eaton N1-125 Isolation Switch
The Eaton N1-125 is a 3-pole molded case switch disconnector from the Eaton NZM series. It features a compact N1 frame with a rated current of 125A, engineered specifically for low-voltage AC power distribution. This switch allows on-load switching without shutting down loads in advance and delivers robust electrical isolation. It is widely used as the main incoming switch and maintenance safety disconnect in control cabinets and distribution panels. When paired with NZM series circuit breakers, it forms a tiered, more reliable power distribution protection system.

Q1: Does the N1-125 feature overload and short-circuit protection?
A1: No. The N1-125 is a switch disconnector. Its core functions are circuit switching and electrical isolation, without automatic tripping protection against overload and short circuits. If protection functions are required, it can be used together with NZM series molded case circuit breakers installed downstream.
Q2: Can accessories be fitted to realize remote signal feedback?
A2: Yes. A variety of standard accessories including auxiliary contacts, door interlocks and padlocking devices are optional. They enable extended functions such as remote feedback of ON/OFF status, cabinet door safety interlock, lockout-tagout and more.
Q3: How about the breaking capacity of the Eaton N1-125?
A3: This series offers high short-circuit breaking capacity. It can cope with fault current conditions likely to occur in industrial power distribution systems and effectively protect the safety of upstream circuits.
Q4: How can I place an order or apply for bulk purchase discounts?
