ABB Low Voltage Products is pleased to announce the new line of non-fusible & fusible disconnect switches 600-1200 amps. The existing OETL/OES offering was redesigned in an effort to help maintain ABB's competitive position in the marketplace. The new design allows ABB to improve cost effectiveness, enhance inventory management efficiency, and ultimately provide a better product for the customer.
In March of 2011, ABB will launch the new non-fusible and fusible switches. In general these products will replace the OETL and OES three and four pole open-style rotary disconnect switches 600-1200 amps. The OS1200L is a completely new offering for the fused disconnect switches. There is no transition necessary for this switch. Non-stock items have an approximate lead of 4-6 weeks as standard.
Features within the range of ABB switch fuses include single pole to four pole versions. The switch fuse mechanism located in any position, increasing the ease of installation and adaptability to different types of cubicle designs. A wide selection of accessories improve the usability of the switch fuses; 6 and 8- pole, changeover, by-pass and mechanically interlocked switch combinations can be built up by means of conversion kits.
The switch fuses are available for all types of fuse links, DIN, BS, NFC, UL, CSA. Switch fuses are also suitable for remote control by the motorized OSM versions. The switch fuse ensures safe operation, protecting both people and equipment. Designed and based on substantial experience of electrical safety, the switch fuse eliminates the risk of electrical accidents.
Having ground fault protection is like having insurance for unforeseen electrical problems. ABB's Ground Fault Equipment Protector can give you the peace of mind that if things go wrong, your equipment will be protected.
The F200 Ground Fault Equipment Protector is the ideal solution to protect equipment against damaging line-to-ground currents by disconnecting all ungrounded conductors of the faulted circuit.
Ground faults can cause serious problems to electrical systems and equipment, since most short circuits initially manifest as undetected ground faults. By adding a ground fault equipment protector (GFEP) to the system, ground faults are detected immediately, preventing serious damage.
There are many applications for GFEP in commercial and industrial segments:
- Oil & gas
- Water/wastewater treatment
- Pharmaceutical industry
- Semiconductor facilities
- Outdoor installations such as ice melting and heat trace
- Water pumps (e.g. fountains, irrigation)
- Heating equipment
A solution always begins with a need. In this case, the engineer of a company who had not previously been ABB Group's Low Voltage Division customer was in the midst of a new design update for an induction machine.
He was requesting a quotation for a Tmax main circuit breaker with a cable operated flange handle mechanism, a design solution similar to that which his company had been using for years. ABB provided a 70% savings in cost, greater competitiveness and higher profits.
ABB's Business Development Management Team understood that to just offer the customer the same solution that he had used in the past might suffice to solve the problem, but greater cost savings Value-Added Solutions were possible.
Not wanting to disappoint the customer, ABB gave them a quote for the requested solution, as well as an interesting alternative solution: an ABB Tmax molded case breaker with a through-the-door handle mechanism. Not only did the ABB alternative save money on the ABB provided components, it also allowed for savings on the panel, by enabling the engineer to use a different, smaller and less expensive panel. The customer really liked the cost savings and the extra thought ABB had given to his needs. He understood that ABB wanted to solve his problem, not just sell a product. The customer was able to achieve an overall savings of 70% over his previous design. He made his company more competitive and more profitable. By offering solutions, ABB gained a satisfied, long-term customer, while the end-user gained a design partner he could count on. The new TMAX series has a hologram on the front, obtained using special anti-imitation techniques, which guarantees the quality and that the circuit breaker is an original ABB product.
The ABB Low Voltage Products division has released the OVR NE12 enclosed surge protective device (SPD), designed for a long service life protecting valuable equipment from damage caused by transient surges from lightning strikes, and surges from upstream equipment and utility load switching. The OVR NE 12 is a multistage protector with fast acting metal oxide varistors (MOV) and an EMI/RFI noise attenuation filter to limit overvoltage to values compatible with the sensitive equipment connected to the network. Extensive damage and expensive repairs can result from transient surges if surge protection is not present. The OVR NE12 is ideal for critical power facilities such as hospitals and data centers, renewable energy installations, water and wastewater systems, and other surge-sensitive manufacturing and commercial operations.
The OVR NE12 is a UL 1449 3rd Edition certified Type 2 SPD contained within a NEMA Type 12 enclosure, designed for installation indoors on the load side of the main breaker or fuse. The new SDP uses MOV technology to achieve a high level of protection performance, and allows for ease of module replacement. Each OVR NE12 comes standard with status lights, alarm, auxiliary contacts, EMI filtering and a fused disconnect. An additional benefit is an optional surge counter/diagnostic LCD display that records the date and time of surges 2kA and above, in addition to providing enhanced information on unit status.
The OVR NE12 is available in three service voltage versions - 240/120 V ac Split Phase, 480 V ac Delta, and 480Y/277 V ac; and two protection levels - 160 and 320 kA per phase (Imax). It is optimally used in addition to ABB OVR DIN rail SPDs at branch panels and equipment, creating a multi-level approach to protection.
Red Lion Controllers
Optional Alarm(s) can be configured to activate according to a variety of actions (Absolute HI or LO, Deviation HI or LO, and Band IN or OUT) with adjustable hysteresis. A standby feature suppresses the alarm during power-up until the process stabilizes outside the alarm region. The second alarm can be configured as a secondary PID output (heat/cool applications). Optional main linear DC output (10 V or 20 mA) can be used for
Marathon Fuse Holder
The Semi-Conductor Fuse Holders (FSM Series) accommodate semi-conductor and high-speed specialty fuses that come in various sizes. This new FSM series is UL approved up to 1200 Amps and 1000 Volts. The high electrical ratings make the Semi-Conductor Fuse Holders ideal for applications such as lithium-ion battery packs, inverters, industrial panels and other energy storage devices.
