Contactors Ex9C
Ex9C Series contactors are primarily intended for industrial applications. They comply with the requirements of IEC / EN 60947-4-1. These contactors are provided in three sizes. Size 18 covers nominal currents of 9, 12 and 18 A in utilisation category AC-3. Size 38 is intended for 25, 32 and 38 A versions. Size 100 is then available with nominal currents of 80 and 100 A. Thus, application to three-phase motors up to 45 kW can be fully covered. The agreed-on Ith thermal current of these contactors is 125 A.
Contactors Ex9C up to 500A
Contactors Ex9C series are intended mainly for industrial applications. They comply with the requirements of IEC / EN 60947-4-1. Splitting into next three frame sizes brings optimization of electrical parameters and mechanical dimensions. Thus, application to three-phase motors up to 400 kW can be fully covered. The agreed-on Ith thermal current of these contactors is up to 610 A
Capacitor contactors Ex9CC
Capacitor contactors Ex9CC are used mainly for switching of power factor correction blocks. These types of contactors are fitted and delivered with special front mounted block of series resistors which ensures early making of auxiliary poles and connect the capacitor to the network via the set of resistors, when the coil is energized. The contactor with this current suppression block can effectively reduce the current impact of the capacitors and operational overvoltage. Utilization category of these contactors is AC-6b.
Mini reverse contactors Ex9CSR
Miniature reversible contactors Ex9CSR brings excellent electric parameters in the form of very compact device. These contactors are used mainly for switching of asynchronnous motors with possibility of change of rotation direction. They can also be used for switching of two circuits when it is necessary to ensure that maximum one circuit is connected.
Overload relays Ex9R
Ex9R thermal overload relays serve to protect motors from overloading. They can be applied either separately with AD5 adapters or in combination with Ex9CS mini contactors or Ex9C contactors. Thermal current is adjustable. The relays are designed with tripping class 10A. Relays are designed as three-phase relays with integrated opening and closing contact.
Accessories for Ex9C
AX41 auxiliary contact units and CCU41 surge suppressor blocks are designed in order to match miniature version of contactors Ex9CS or Ex9CSR. Auxiliary contact units are available with four contacts with all posible contact combinations. Contactors Ex9C line (Ex9C, Ex9Ci, Ex9CR) share accessories, i.e. available portfolio can be used for all sizes of contactors (except miniature ones). Contactors can be equipped with one front-mounted unit (AX42 or TDD4), two units of side-mounted contact AX43/44 (one from the left, the other from the right) and surge suppressor block CCU42/43.
Air Circuit Breakers Ex9A
The new line Ex9A offers very complex functional devices range. They provide not only the basic function of circuit breakers or switch disconnectors, but also a complete networks analysis with the ability to communicate with advanced control systems, alarm function and power switching relays. The circuit breakers and switch disconnectors are available in three frame sizes as fixed and withdrawable version of 3P and 4P devices.
MCCB Ex9M
Moulded Case Circuit Breakers Ex9M TM are intended for varying applications in the sector of residential and office premises, commercial and administrative centres but also for highly demanding industrial applications. Testing according to IEC / EN 60947-2 standards ensures functions and reliability for wide variety of applications including isolation.
Disconnectors Ex9MSD
AC versions of MCCB based Switch Disconnectors Ex9MSD are used as a main switch in many various circuits. They are intended primarily for applications in power distribution.
Accessories for Ex9M
Accessories suitable for Moulded Case Circiut Breakers Ex9M. It is possible to supplement or modify function of basic circuit breaker by installing of suitable accessories
