UP1 Undervoltage Release Switch for Operators Safety

The new UP1 undervoltage switch monitors the supply voltage and actuates a trip release when there is an intense drop in voltage or when the supply voltage is interrupted. As soon as the supply voltage returns in full, the machine or equipment does not automatically restart in an uncontrolled manner, but must be consciously switched on again. Using this function, dangerous situations for operating personnel as well as for the surroundings of the device itself can be prevented.

The UP1 is a 2-pole circuit breaker with additional undervoltage monitoring actuates a trip re-lease with a loss of voltage or an intense voltage drop. The breaker is available with rocker actuation for snap-in mounting or with push-button actuation for both snap-in mounting as well as screw fitting. Protection covers against the ingress of dust and spray water make the use of the breaker in harsh environments such as wood-, masonry- or metal-workings possible.

The requirement for the use of undervoltage protection is in existence for applications such as gardening equipment, gardening shredders, floor cleaning and sanding devices, electrical tools such as circular saws, band saws, grinding machines and drills. Further examples are fuel pumps, coffee-milling devices, fruit juice squeezing machines and fruit juice centrifuges.

The UP1 undervoltage circuit breaker is configured differently in its hardware for various net-work supply voltages und must be therefore ordered for the appropriate supply voltage. Rated switching category is AC-1 16A / AC-3 14.5A @ AC 240 V. The breakers are approved to IEC 60947, UL 508, CSA 22.2 No.14-95 and also contain a horsepower rating.

Finder has introduced surge protection devices (SPD) designed specifically for photovoltaic (PV) panel installations.  Additions to its popular 7P Series of SPDs, three new Type 2 surge arresters will protect PV systems from the effects of lightning strike and electrical switching transients.  The products are already supporting the company’s own PV panels at its primary manufacturing plant.

Featuring encapsulated spark gap and/or replaceable varistor modules, the three devices protect the more vulnerable DC side of commonly used earth free and mid point earthed PV systems.  The range includes: the 7P.26.9.420, providing 2 varistors and 1 spark gap for 420V DC systems; the 7P.23.9.700, providing 3 varistors for 700V DC systems and the 7P.23.9.000, providing 3 varistors for 1000V DC systems.

Each device integrates both a visual indicator and a signalling contact to warn when a varistor module needs replacing.  Connection to the signalling contact is via a convenient plug-in terminal block.  The SPDs comply with EN 61643-11 standard and can be 35mm rail (EN 60715) mounted.

Finder’s introduction of a range of SPDs tailored to the needs of PV installations comes at a time when UK government Feed-In Tariffs (FITs) appear to have stimulated a step increase in interest in PV system in the country.  The UK is now the fastest growing market for PV solar energy installations, estimated to produce 96MW of electricity in 2010 compared with 6MW in 2009.

At the same time, a prospective revision of the UK wiring regulations, placing far more emphasis on the provision of protection from electrical surges, has meant there is a resurgence of interest in associated products, in particular varistor and spark gap type SPDs.

PV panels at Finder’s prime manufacturing site in Almese near Turin in North West Italy have been producing an output power of 55kW since early 2009, equating to 61,000 kWh/year.  So pleased with the performance, the company has this month commissioned a further 60kW of PV panels, which of course will be protected by the new 7P Series surge arresters.

Constructed using multicrystalline silicon PV modules, Finder’s initial PV system is calculated to have reduced CO2 emissions by about 37 tons/year, achieving annual cost savings of around 11 TOE (tonnes of oil equivalent).
