In Low Voltage industrial installations, capacitors are mainly used for reactive energy correction (raising the power factor).
When these capacitors are energized, overcurrents of high amplitude and high frequencies (3 to 15 kHz) occur during the transient period (1 to 2 ms).
The amplitude of these current peaks, also known as "inrush current peaks", depends on the following factors.
The network inductances.
The transformer power and short-circuit voltage.
The type of power factor correction.
The presence of harmonics and the network's voltage tolerance lead to a current, estimated to be 1.3 times the nominal current ln of the capacitor, permanently circulating in the circuit.
Type DP contactors provide high performance with flexibility and reliability, designed to match numerous applications.
ABB has additionally performed definite purpose testing for air conditioning (h.r.c.) applications with AF and AS/ASL series contactors.

Type TBC, TAL, TAE & TNL Ring-Tongue Termination
Rolling stock applications necessitate compliance to national and international standards tailored to railway environments.
In order to improve reliability and durability, most railway applications employ specific connection methods, such as ring-tongue termination.
Coil surge suppression is also popular among rail applications.
ABB's AF Series contactors are equipped with integral surge suppression in the form of a free-wheel diode, eliminating the need for additional accessories.
AF Series devices are also immune to short time voltage interruption (or voltage dips) up to 20 ms.
Control networks typically utilizing DC (battery source) with wide voltage ranges: 0.7 Uc to 1.25 Uc (Operating limits included as Uc)
Type GA/E GAF AF DC Circuit Switching
The new GAF range contactors are the latest addition to ABB's well established A/AF range.
This further extends our offering of contactors for DC switching at voltages up to 1000 V DC.
The GAF contactors utilize all the well known features of the existing A/AF range such as modern and compact design.
In addition all the benefits from the AF coil technology and reliability of a proven contactor design.
These contactors are rated for DC-1 or DC general purpose applications according to IEC 1000V DC or cULus 600V DC.
The new GAF contactors share the external dimensions of its corresponding standard AF contactor.
50 to 5000 A Bar Mounted
R contactors with variable number of poles and their variants (contactors with N.C. + N.O. poles, couplers) are used for controlling power circuits up to 1000 V AC or 1500 V DC.
They are designed with common standard components.
With the combination of these elements and the adaptation possibilities, special versions can be provided.

B Miniature Non-Reversing, Mechanically Interlocked, 3-Pole
ABB miniature contactors, Type B6 and B7, are designed for commercial and light industrial applications where panel space is at a premium.
The mechanical interlock between the two contactors mechanically prevents switch-on of one contactor for as long as the other contactor is still on and vice versa.
If reversing contactors are switched over too quickly, this involves the risk of a phase-to-phase short-circuit.

Flexible overload protection
Type T, TF & TA Thermal Overload Relays
Thermal overload relays are electromechanical protection devices for the power circuit.
They offer reliable protection for motors in the event of overload or phase failure.
The thermal overload relays are three pole relays with bimetal tripping elements.
The motor current flows through the bimetal tripping elements and heats them directly and indirectly.
In case of an overload (over current), the bimetal elements bend as a result of the heating.
This leads to a release of the relay and a change of the contacts switching position (95-96 / 97-98).

TURCK's MK13-UNF-Ex0/24VDC and MK13-UPF-Ex0/24VDC are single channel switching amplifiers with intrinsically safe input circuits. They are used to isolate and transfer discrete signals from a hazardous location to a non-hazardous location. Inputs are typically NAMUR sensors or dry contacts, although devices providing a variable resistance conforming to DIN 19234 may be used - e.g. variable resistors, thermistors, etc.
