Description :
Modular contactors are used for installation into home switch cabinets with a number of different purposes, such as:
- switching-on electric lighting
- switching-on all types of pumps
- switching-on electric heating appliances
- switching-on electric motors
The basic types of the above mentioned modular contactors are R20, R25, R40 and R63, intended for installation on
standard mounting rails with a width of 35 mm (EN 50022).
The contactors can be leaded by means of a lead cover, also available is an auxiliary contactor block RH 11.
A great advantage of our contactors is a relatively silent operation, long lifetime of the mechanism, and high-quality
manufacturing of the mechanism itself.
Technical specifications according to:
EN60947-4-1; EN60947-5-1; VDE 0660, IEC 947-4-1; IEC 947-5-1

EMR4-A Unbalance Relay – Reliable Phase Loss Detection
Unbalance Relay Protecting the motor from destruction
The EMR4-A unbalance relay with its 22.5 mm module width is the ideal protective device for phase loss protection. The detection of phase loss on the basis of phase shift means that reliable phase loss detection is ensured and overloads, even when large amounts of energy are regenerated to the motor.
The relay can be used for protecting motors with a rated voltage of UN = 380 V – 415 V at 50 Hz.
Features of the EMR4-A
* Phase loss detection even with 95 % phase regeneration
* Phase sequence detection
* On-delay 0.5 s
* LED status indication
* The relay has its own power supply, i.e. an additional supply voltage is not required.

Circuit-Breakers and Switch-Disconnectors up to 6300 A
Intelligent and capable of communication
The IZM was the realisation of an idea for air-break circuit-breakers which has now become the standard worldwide. The compact circuit-breaker in the rated current range 630 to 6300 A utilises the very latest protective measures from the field of panel building – new technology which, in many respects, has set new standards: in terms of performance with higher switching capacities; in terms of function through the increased signalling and information features; and in terms of handling through front access to the operating components and in terms of installation through the identical connection positions for fixed or withdrawable installation.
The IZM is available in three frame sizes up to 6300 A. The new compact frame size 1 from 630 A to 1600 A only requires a 400 mm wide area in the control panel – and that saves space. Frame size 2 covers the wide range from 800 – 3200 A, simplifying both engineering and handling. The new frame size 3 up to 6300 A is even more compact and now has its operating panel situated in the centre. The same door cutout fits all breaker sizes.
Accessories and auxiliary equipment are identical for the entire range, thus enabling retrofitting to be carried out on site for all versions. Each size of IZM is also available as an IN switch-disconnector. Both accessories and operation are identical to those of the IZM circuit-breaker.
The IZM: Crammed with good ideas.

Multi-Switch improves electrical supply continuity. The principle of operation guarantees a higher reliability level than that achieved using a single UPS (on-line with automatic bypass) or several UPS in parallel.
PRINCIPLE OF OPERATION
The Multi-Switch provides electrical distribution and remote management for up to eight network users, powered from either one or two direct mains supplies or UPS or a combination of both.
Multi-Switch can connect each user (up to eight, each with a maximum power demand not greater than 3A), to either of the two power sources (A and B). Load demand is shown on the LCD. See “principle of operation” diagram.
PROTECTION AGAINST POWER SUPPLY FAILURES
If one of the two power sources fails or falls outside specification, Multi-Switch will transfer the connected loads to the second power source (switching is instantaneous even if the two sources are in phase).
PROTECTION AGAINST FAULTS WITH THE LOAD
If a fault occurs with one of the loads (for example due to a short-circuit or overload), Multi-Switch will disconnect the load to prevent disruption to the others.
Multi-Switch protects sensitive installations from both power and hardware faults.
