Moulded Case Circuit Breakers
Moeller's NZM1, 2, 3 and 4 moulded case circuit breakers and PN & N main switches have a uniquely uniform approach to mounting, operation and switching with accessories saving time and money.
Available in four frame sizes, with toggle or rotary handle options, the NZM1 - 4 are suitable for a wide variety of applications. Contacts from the RMQ-TiTan range of control circuit devices simply clip in from the front of the circuit-breakers to provide remote status indication.
The optional data management interface for the breakers with electronic trips improves diagnostics and allows rapid fault analysis, so minimising downtime.
