RMMZ11

RMMZ11 series trip relays are highly reliable products providing top performance, suitable for applications in particularly harsh and unsettled environments, such as high voltage electricity distribution stations and medium voltage substations:

The typical application is

• for interfaces between protections or automation systems and HV / MV breakers, for alarm transmission and very rapid trip operations.
• multiplication of trip contacts in minimal time intervals

Equipped with 8 changeover contacts for exceptional flexibility of configuration.

Switching time < 8ms (first contact) + 5ms (bounces)

Knurled contacts to provide lower ohmic resistance thanks to the multiple electrical connection points: extended electrical life expectancy of the component, optimal performance for strongly inductive DC loads and for very low loads, such as in the case of interface signals.

High breaking capacity for controlling very heavy duty DC loads, also with intensive switching frequency.

Elevated production versatility. Nominal voltage available from 12 to 220VDC/440VAC, with multiple operating ranges. Facility to adapt the products to meet specific application requirements.

The typical application sectors are among the most demanding, such as electricity generating stations, electrical transformer stations, fixed equipment for railways, or industries using continuous production processes (chemical and petrochemical, rolling mills, cement works, etc.).
